Setting OnItemClickListener for RecyclerView

noreply@blogger.com (Awesome Idiot) — Fri, 11 Jul 2014 12:49:00 +0530

In our previous example we saw how to use RecyclerView instead of ListView.

Let's see how to set OnItemClickListener in RecyclerView.

Adding OnItemClickListiner to Recycler View.
By default, RecyclerView doesn't have onItemClickListiner similar to ListView.

1. Implement onItemClickListener in ViewHolder.

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
       
    @Override
        public void onClick(View v) {

        }
  
    }

2. Create an Interface OnItemClickListener

3. Create an empty method

public void onItemClick(View view , int position);

public interface OnItemClickListener {
   public void onItemClick(View view , int position);
 }

4. Pass view and position from onClick


    @Override
    public void onClick(View v) {
       mItemClickListener.onItemClick(v, getPosition()); //OnItemClickListener mItemClickListener;
    }

5. SetOnItemClickListiner from adapter.

    adapter.SetOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(View v , int position) {
            // TODO Auto-generated method stub

        }
    });

Creating Animated, Horizontal, Vertical ListView using Recycler View.

noreply@blogger.com (Awesome Idiot) — Fri, 11 Jul 2014 12:36:00 +0530

Recylcer view is an updated version of ListView.

Recylcer View can also be used to create Horizontal ListView by setting LinearLayoutManager's Orientation to HORIZONTAL, it can be done either by setting it in a method or while creating an instance.


    LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(getApplicationContext());
    mLinearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);


    LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);

Initilize Recycler View


        RecyclerView mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);

fragment_main.xml


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="vee.android.sample.recycler.view.MainActivity$PlaceholderFragment" >

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true"
        android:background="#FFE5E5E5"
        android:scrollbarStyle="insideOverlay" />

</RelativeLayout>

Setting hasFixedSize to true will increase the performance of Recylcer, but one has to careful while using it, It has to be set to true only if the size of the adapter doesn't change.

mRecyclerView.setHasFixedSize(true);

Set LayoutManager that Recycler View will use. This has lot of other benifits which will be cover later.
Using this we can set the RecyclerView to Horizontal or Vertical.

mRecyclerView.setLayoutManager(mListLayoutManager);

Sets the ItemAnimator that will handle animations involving changes to the items in this RecyclerView.

mRecyclerView.setItemAnimator(new DefaultItemAnimator());

Hence,

        mRecyclerView.setHasFixedSize(true);
        mListLayoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(mListLayoutManager); 
        ListAdapterHolder adapter = new ListAdapterHolder(mActivity);
        mRecyclerView.setAdapter(adapter);
        mRecyclerView.setItemAnimator(new DefaultItemAnimator());

Creating an adapter for RecyclerView. This is bit different from before.
Recycler view's adapter accepts RecyclerView.Adapter<VH extends ViewHolder> only

ListAdapterHolder

public class ListAdapterHolder extends RecyclerView.Adapter<ListAdapterHolder.ViewHolder>{

    public class ViewHolder extends RecyclerView.ViewHolder {

    }

}

Extend your ListAdapterHolder with RecylcerView.Adapter and pass your ViewHolder extending RecyclerView's ViewHolder.

Add Unimplemented Methods and a constructor.


import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.view.ViewGroup;

public class ListAdapterHolder extends RecyclerView.Adapter<ListAdapterHolder.ViewHolder> {

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent , int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder , int position) {

    }

    @Override
    public int getItemCount() {
        return 0;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        public ViewHolder(View view) {
            super(view);
        }

    }
}

Return the number of list Items "getItemCount"

    @Override
    public int getItemCount() {
        return count;
    }

Inflate your view "onCreateViewHolder"

Inflate the view. To know which overloaded method to be used while inflating, do have a look at the best article.


    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent , int viewType) {
        final LayoutInflater mInflater = LayoutInflater.from(parent.getContext());
        final View sView = mInflater.inflate(R.layout.single_list_item, parent, false);
        return new ViewHolder(sView);
    }

Declare and intiate views in "ViewHolder"

        public ViewHolder(View view) {
            super(view);
            vName = (TextView) view.findViewById(R.id.list_name);
            vSex = (TextView) view.findViewById(R.id.list_sex);
            vId = (TextView) view.findViewById(R.id.list_id);
            vAge = (TextView) view.findViewById(R.id.list_age);
         }

Layout for ListView/RecyclerView

single_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:padding="5dp"
    android:weightSum="4" >

    <TextView
        android:id="@+id/list_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/list_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/list_sex"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/list_age"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

</LinearLayout>

Add data to your view "onBindViewHolder"

    @Override
    public void onBindViewHolder(ViewHolder holder , int position) {
        holder.vId.setText("ID: " + mUserDetails.get(position).getId());
        holder.vName.setText("Name: " + mUserDetails.get(position).getName());
        holder.vSex.setText("Sex: " + mUserDetails.get(position).getSex());
        holder.vAge.setText("Age: " + mUserDetails.get(position).getAge());
    }

That's it.

Using Simple SharedPreferences in Android.

noreply@blogger.com (Awesome Idiot) — Sun, 15 Jun 2014 04:37:00 +0530

SimpleSharedPreferences on GitHub

Shared preferences are used to save values permanently within the app. It is saved in an XML file using Key-Value pair.

SharedPreferences provide API's to read and write these Key-Value pairs.

mContext = getApplicationContext();
// mContext = getActivity().getApplicationContext(); // In Fragment
SharedPreferences mPreferences = PreferenceManager.getDefaultSharedPreferences(mContext)
SharedPreferences.Editor mEditor = mPreferences.edit();

mEditor.putString("STRING_KEY", "STRING_VALUE"); // mEditor
mEditor.commit(); // mEditor
...
...
...
mEditor.putInt("INTEGER_KEY", 50); // mEditor
mEditor.commit(); // mEditor
...
mPreferences.getString("STRING_KEY", "STRING_DEF_VALUE");  // mPreferences
...

To put a Value an Editor has to be created. After Putting the values, editor has to be committed.
Editor Object is used to put values & SharedPreferences Object is used to get Values.

This is quite confusing.

If an key is wrongly used to fetch values then ClassCastException is thrown.

Let try SimpleSharedPreferences to do the same.


SimpleSharedPreferences mPreferences = new SimpleSharedPreferences(mContext);
mPreferences.putString("STRING_KEY", "STRING_VALUE");  // Put String
mPreferences.putInt("INTEGER_KEY", 50);  // Put Int
mPreferences.getString("STRING_KEY", "STRING_DEF_VALUE"); // Get String

No need to create multiple Objects.

If an key is wrongly used to fetch values then ClassCastException is thrown. Clearly stating the type.

mPreferences.getString("INTEGER_KEY", "STRING_DEF_VALUE"); // Get String with Integer Key

Error:
==========================================================
ClassCastException : INTEGER_KEY's value is not a string
==========================================================

Other APIs in SimpleSharedPreferences

public boolean incrementAppOpenedCount() // Increment's App opened count

public int getAppOpenedCount() // Get the number of times app opened

public boolean isLogEnabled() // Log Status

public void setLogEnabled(boolean enableLog)// default false

Refer SimpleSharedPreferencesDemo for all the available API's

In this, putStringSet / getStringSet is back ported to API-1 & hence can be used pre API level 11

All APIs are available as in `SharedPreferences` and `SharedPreferences.Editor` including registerOnSharedPreferenceChangeListener & unregisterOnSharedPreferenceChangeListener

No Edit, No Commit, Only Put & Get.

Custom ListView with CheckBox & Header, with Select-All / DeSelect-All functionalities

noreply@blogger.com (Awesome Idiot) — Fri, 6 Dec 2013 02:02:00 +0530

In our last post we saw how to create simple custom listview, It does not have any state to save when scrolled. But implementing ListView with check boxes & saving the selected items are little tricky. since listview elements are destroyed & recreated.

ListView Model

To handle selected items, we need a variable to save the selected state of each items. Hence we will be using SparseBooleanArrays (I have no clue how I came across this)

This post is a continuation of prev post, so please refer prev post incase if you have any queries.

Create a ListView in the View of our current layout. "activity_main.xml" (refer last post)

Create a customView "custom_list_view.xml"

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:background="#EEE"
 android:minHeight="90dp"
 android:padding="4dp"
 tools:ignore="HardcodedText,ContentDescription" >

    <TextView
 android:id="@+id/textView"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_centerVertical="true"
 android:layout_marginLeft="31dp"
 android:layout_toRightOf="@+id/imageView"
 android:text="Content"
 android:textSize="21sp" />

    <ImageView
 android:id="@+id/imageView"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentLeft="true"
 android:layout_centerVertical="true"
 android:layout_marginLeft="15dp"
 android:maxHeight="60dp"
 android:maxWidth="60dp"
 android:scaleType="fitXY"
 android:src="@drawable/ic_launcher" />

    <CheckBox
 android:id="@+id/checkBox"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentRight="true"
 android:layout_centerVertical="true"
 android:focusable="false"
 android:focusableInTouchMode="false"
 android:padding="16dp" />

</RelativeLayout>

we get this with the above code.

Inflate this layout as adapter to ListView (refer last post)

Inflating header to custom listView.

This time let's add header to listview (this will scroll with list view, this will be useful when header is different from that of contents.)
Inflate header similar to that of custom listview. Add header before setting adaper to listview.

Create a customView "custom_list_view_header.xml"

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:background="#EEE"
 android:minHeight="90dp"
 android:padding="4dp"
 tools:ignore="HardcodedText,ContentDescription" >

    <TextView
 android:id="@+id/textView1"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_centerHorizontal="true"
 android:layout_centerVertical="true"
 android:layout_marginLeft="31dp"
 android:text="Content"
 android:textSize="21sp" />

    <CheckBox
 android:id="@+id/checkBox_header"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentRight="true"
 android:layout_centerVertical="true"
 android:focusable="false"
 android:focusableInTouchMode="false"
 android:padding="16dp" />

</RelativeLayout>

ListView Header

    @Override
    protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mListView = (ListView) findViewById(R.id.list_view);
CustomAdapter adapter = new CustomAdapter(this);
final View headerView = getLayoutInflater().inflate(R.layout.custom_list_view_header, mListView, false);
checkBox_header = (CheckBox) headerView.findViewById(R.id.checkBox_header);
mListView.setAdapter(adapter);

    }

when activity is recreated, header is added again to avoid this, header is added inside custom if else.

if (isNotAdded)
 {
    final View headerView = getLayoutInflater().inflate(R.layout.custom_list_view_header, mListView, false);
    checkBox_header = (CheckBox) headerView.findViewById(R.id.checkBox_header);
    isNotAdded = false;
 }

Create a sub class CustomAdapter extending BaseAdapter, add unimplemented methods

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    View mView = convertView;

    if (mView == null) {

/*
 * LayoutInflater
 */
final LayoutInflater sInflater = (LayoutInflater) sActivity.getSystemService(
Context.LAYOUT_INFLATER_SERVICE);

/*
 * Inflate Custom List View
 */
mView = sInflater.inflate(R.layout.custom_list_view, null, false);

    }

    /* **************CUSTOM LISTVIEW OBJECTS**************** */

    /*
     * DO NOT MISS TO ADD "mView"
     */
    final TextView sTV1 = (TextView) mView.findViewById(R.id.textView);
    final ImageView sIMG = (ImageView) mView.findViewById(R.id.imageView);
    final CheckBox mCheckBox = (CheckBox) mView.findViewById(R.id.checkBox);

    /* **************CUSTOM LISTVIEW OBJECTS**************** */

    /* **************ADDING CONTENTS**************** */
    sTV1.setText(MainActivityjacobe.textviewContent[position]);
    sIMG.setImageResource(R.drawable.logo);

    /* **************ADDING CONTENTS**************** */

    /*
     * Return View here
     */
    return mView;
}

Add "OnCheckedChangeListener" to check box.

Set each checkbox, to checked/unchecked from SparseBooleanArray

  SparseBooleanArray mChecked = new SparseBooleanArray();

    mCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if (isChecked) {

/*
 * Saving Checked Position
 */
mChecked.put(position, isChecked);

    } else {
/*
 * Removed UnChecked Position
 */
mChecked.delete(position);

    }

}
    });

    /*
     * Set CheckBox "TRUE" or "FALSE" if mChecked == true
     */
    mCheckBox.setChecked((mChecked.get(position) == true ? true : false));

To select all the CheckBoxes in listview, when header CheckBox is selected & vice-versa

Set "setOnClickListener" NOT "setOnCheckedChangeListener" for CheckBox in header "checkBox_header"

  
    /*
     * Select All / None DO NOT USE "setOnCheckedChangeListener" here.
     */
    checkBox_header.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

    /*
     * Set all the checkbox to True/False
     * here reference for `i` is count, do not use `mChecked.size()`
     */
    for (int i = 0; i < count; i++)
    {
mChecked.put(i, checkBox_header.isChecked());
    }
    /*
     * Update View
     */
    adapter.notifyDataSetChanged();

}
    });

Set "OnItemClickListener" after adding Adapter

Since header is added position = position - 1 only when position > 0

/*
 * Set "OnItemClickListener" after adding Adapter
 */
mListView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {

/*
 * Use "if else" only if header is added
 */
if (position == 0)
{
    Toast.makeText(getApplicationContext(),
    checkBox_header.getId() + "\n" + checkBox_header.isChecked(),
    Toast.LENGTH_SHORT).show();
} else {
    position = position - 1; // "-1" If Header is Added
    Toast.makeText(getApplicationContext(),
    textviewContent[position] + "\n" + mChecked.get(position),
    Toast.LENGTH_SHORT).show();
}

    }
});

To uncheck header CheckBox when CheckBoxes in ListView are unchecked & check the header CheckBox when all CheckBoxes in ListView are checked manually

    mCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if (isChecked) {

/*
 * Saving Checked Position
 */
mChecked.put(position, isChecked);

/*
 * Find if all the check boxes are true
 */
if (isAllValuesChecked())
{
    /*
     * set HeaderCheck box to true
     */
    checkBox_header.setChecked(isChecked);
}

    } else {
/*
 * Removed UnChecked Position
 */
mChecked.delete(position);

/*
 * Remove Checked in Header
 */
checkBox_header.setChecked(isChecked);

    }

}
    });

/*
 * Find if all values are checked.
 */
protected boolean isAllValuesChecked() {

    for (int i = 0; i < count; i++) {
if (!mChecked.get(i))
{
    return false;
}
    }

    return true;
}

CustomListView with CheckBox on GitHub

Final Required View

A Simple Custom ListView in Android with Images & Text

noreply@blogger.com (Awesome Idiot) — Thu, 5 Dec 2013 16:39:00 +0530

Let's start with simple requirement.
A list view containing a image & 2 TextViews as below.
To achieve this one has to create an model of single list in a seperate layout & inflate it to listview.
Let's do it.

Create a ListView in the View of our current layout. "activity_main.xml"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

</RelativeLayout>

we get this with the above code.

Inflate this layout as adapter to our listView.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mListView = (ListView) findViewById(R.id.list_view);
        CustomAdapter adapter = new CustomAdapter(this);
        mListView.setAdapter(adapter);

    }

Create a sub class CustomAdapter extending BaseAdapter, add unimplemented methods

    public class CustomAdapter extends BaseAdapter
    {

        Activity sActivity;

        public CustomAdapter(final Activity mActivity) {
            this.sActivity = mActivity;
        }

        @Override
        public int getCount() {
            /*
             * Length of our listView
             */
            count = MainActivity.textview1.length; //Refer Below
            return count;
        }

        @Override
        public Object getItem(int position) {

            /*
             * Current Item
             */
            return position;
        }

        @Override
        public long getItemId(int position) {
            /*
             * Current Item's ID
             */
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            View mView = convertView;
            if (mView == null)
            {
                /*
                 * LayoutInflater
                 */
                LayoutInflater sInflater = (LayoutInflater) sActivity
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                /*
                 * Inflate Custom List View
                 */
                mView = sInflater.inflate(R.layout.custom_list_view, null, false);

            }

            /* **************CUSTOM LISTVIEW OBJECTS**************** */

            TextView sTV1 = (TextView) mView.findViewById(R.id.textView1);
            TextView sTV2 = (TextView) mView.findViewById(R.id.textView2);
            ImageView sIMG = (ImageView) mView.findViewById(R.id.imageView1);

            /* **************CUSTOM LISTVIEW OBJECTS**************** */

            /* **************ADDING CONTENTS**************** */
            sTV1.setText(MainActivity.textview1[position]);
            sTV2.setText(MainActivity.textview2[position]);
            sIMG.setImageResource(R.drawable.ic_launcher);
            /* **************ADDING CONTENTS**************** */

            /*
             * Return View here
             */
            return mView;
        }

Add OnItemClickListener to get clicked item

import android.widget.AdapterView.OnItemClickListener;

        mListView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id) {

                Toast.makeText(getApplicationContext(),
                        textview1[position] + "\n" + textview2[position], Toast.LENGTH_SHORT)
                        .show();

            }
        });

Finally with Activity and CustomAdapter.

What's new in Android 4.4

Android 4.4 is designed to run fast, smooth, and responsively on a much broader range of devices than ever before.
Android 4.4 targets to run efficiently, even on low-memory devices. Core system processes are trimmed to use less heap, and they now more aggressively protect system memory from apps consuming large amounts of RAM.
When multiple services start at once — such as when network connectivity changes — Android now launches the services serially, in small groups, to avoid peak memory demands.
New NFC capabilities through Host Card Emulation.
Printing framework
Storage access framework
Low-power sensors
Step Detector and Step Counter Read more about it here.

Get data from URL in Single Line - Android

noreply@blogger.com (Awesome Idiot) — Sat, 31 Aug 2013 07:28:00 +0530

Send httpget request in Android, receive, read response & print result in single line.

Any connection to server has to called inside Async Task.

 <uses-permission android:name="android.permission.INTERNET" />

 /* Single line request with response */ 

  System.out.println(EntityUtils.toString(new DefaultHttpClient().execute(new HttpGet("http://www.VenomVendor.com")).getEntity()));

/* Equivalent for the above */

  String url = "http://www.VenomVendor.com";
  HttpClient httpClient = new DefaultHttpClient();
  HttpGet httpGet = new HttpGet(url);
  HttpResponse response = httpClient.execute(httpGet);
  HttpEntity httpEntity = response.getEntity();
  String res = EntityUtils.toString(httpEntity);
  System.out.println(res);

 /* Best Practice, *****Also Surround with try-catch***** */

  String url = "http://www.VenomVendor.com";
  HttpClient httpClient = new DefaultHttpClient();
  HttpGet httpGet = new HttpGet(url);
  HttpResponse response = httpClient.execute(httpGet);
    if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK && response.getEntity()!=null)
      {
        HttpEntity httpEntity = response.getEntity();
        String res = EntityUtils.toString(httpEntity);
        System.out.println(res);
      }
    else
      {
      Log.wtf("Error in Server","Operation Success, Patient Dead");
      }

 /* OLD J2ME Method *** DIFFRERENCE IS IN CONVERTING THE RESPONSE TO `STRING` *** */
 
 String url = "http://www.VenomVendor.com";
 HttpClient httpClient = new DefaultHttpClient();
 HttpGet httpGet = new HttpGet(url);
 HttpResponse response = httpClient.execute(httpGet);
 HttpEntity httpEntity = response.getEntity();
 InputStream iStream = httpEntity.getContent();

Phonegap API differences

noreply@blogger.com (Awesome Idiot) — Mon, 13 May 2013 15:52:00 +0530

In this post, I will be sharing the differences in invoking phone dialer & mail functions using phonegap API.

What is Phonegap?

It enables software programmers to build applications for mobile devices using JavaScript, HTML5 and CSS3, instead of lower-level languages such as Objective-C/core-java. The resulting applications are hybrid, meaning that they are neither truly native (all layout rendering is done via the webview instead of the platform's native UI framework) nor purely web based (they are not just web apps but packed for appstore distribution, and have access to part of the device application programming interface).

For now, I will be sharing only about Phone-dialer and Emailcomposer api. Before making those api calls in IOS, you need play around with xcode to make it work i.e., copy certain files to project, details below. Whereas, in case of Android, it just invoking a simple dom function. Also, You will have to invoke the API using onclick/tap/touch listener over respective javascript libraries.

PhoneDialer API:

IOS

Copy the .h and .m files to your project.
Copy the .js file to your www folder
Include the .js file with a script tag in your index.html
Add "phonedialer" ----> "PhoneDialer" to your plugins mapping in config.xml
Once done, wrap this function in tap/touch listener.

 window.plugins.phoneDialer.dial('12-345-6789');

Android

Simple, Just wrap this function in tap/touch listener.

document.location.href ='tel: + 12-345-6789';

Email Composer API:

IOS

You will need to add MessageUI.framework to your project if it is not already included.

Just add the EmailComposer.h EmailComposer.m files to your Plugins Folder.

Place the EmailComposer.js file in your app root, and include it from your html.

Add to Cordova.plist Plugins: key EmailComposer value EmailComposer.

Once done, wrap this function in tap/touch listener.

window.plugins.emailComposer.showEmailComposer("","", "john.doe@example.com", "", "",false);

Android

Simple, Just wrap this function in tap/touch listener.

document.location.href ='mailto:john.doe@example.com';

Adding "Comment using Google+" in Custom Blogger Templates

noreply@blogger.com (Awesome Idiot) — Fri, 19 Apr 2013 03:23:00 +0530

Blogger is updating all it's tools, in it timeline, Blogger recently improved Blogger template HTML Editor , now it has introduced "Comment Using Google+" which is similar to "Comment using <OpenID>"

Users can now comment using his/her G+ id, if user does not have G+ id, they will be prompted to create Google+ id.

For developers/blogger upgrading to Google Plus Comment box, Current comments or previous comments, that was commented using blogger profile will remain same. But comments posted using 3rd party widgets such as Disqus will disappear.

To activate Google+ Comment box
Go to
--> Blogger.com
--> Select your blog
--> Select Google+ in the left Panel
--> "Check" Use Google+ Comments on this blog

You might end up in trouble if you are using Custom Templates such as mine.
To activate "Comment using Google+" in Custom Templates, you have to REPLACE your current comment box code with Google+ Comment box.

Plz backup your template incase if anything goes wrong.

To backup your template, go to your blog's dashboard --> templete --> Backup/Restore (in top right) --> Download Full template

Search for

<b:if cond='data:blog.pageType == &quot;item&quot;'>

you might find many, check whether it has code related to comment section, if so delete the code between

<b:if cond='data:blog.pageType == &quot;item&quot;'>

code code code code code code code code code

code code code code code code code code code

</b:if>

and replace it by

<div class='cmt_iframe_holder'
expr:data-href='data:post.canonicalUrl'
expr:data-viewtype='data:post.viewType'/>

Now it should look like


<b:if cond='data:blog.pageType == &quot;item&quot;'>
<div class='cmt_iframe_holder'
expr:data-href='data:post.canonicalUrl'
expr:data-viewtype='data:post.viewType'/>
</b:if>

Save and you are ready to use Comment using Google Plus in your custom template, however there is no guarantee, that this might work until you figure out correct position to replace code.

See demo of Comment box implemented in this blog.

Pinterest layout for Sencha touch 2

noreply@blogger.com (Awesome Idiot) — Sun, 14 Apr 2013 01:10:00 +0530

In this post, I will be sharing my knowledge on implementing pinterest layout on Sencha-Touch 2.

Know How To:

All I did was, mapped the piece of code, that generates pinterest style in jquery. I just ported the jquery methods to corresponding SenchaTouch/Javascript methods. Excellent tutorial on how to create pinterest layout

Demo

Snippet

This is the function that does the magic, snippet at app/controller/PinterestController.js near line 89.


generatePinterest : function() {  
                /**  
                 *This is the function that does the Pinterest Magic!!!   
                 */  
                var colCount = 0;

                Ext.select('.block').elements.forEach(function(element,

                       + margin;  
                })  
             }

At the instance of adding the pinterest layout to the viewport, resize listener checks for the screen height/width and invokes the generatePinterest fn, which preserves the layout.


                generateView : function(showMain) {  
                console.log('i')  
                // console.log(showMain)  
                Ext.getCmp('cardLayout').destroy();  
                Ext.Viewport.add({  
                  // xclass : PinterestStyle.view.Communitypt,  
                  xclass : showMain,  
                  showAnimation : {  
                     type : 'pop',  
                     duration : 1000,  
                     direction : 'up'  
                  },  
                  listeners : {  
                     resize : function() {  
                       console.log(this)  
                       this.generatePinterest();  
                       //resize() listener for viewport width/heigth and the layout is preserved  
                     },  
                     scope : this  
                  }  
                })  
                this.generatePinterest();  
                //call on page invocation

Getting Started with Google MapV2 for Android Apps

noreply@blogger.com (Awesome Idiot) — Mon, 8 Apr 2013 03:45:00 +0530

This is the Tutorial for adding Google Maps V2 to your Android Project.
MapV1 is depracted, you cannot generate Map API - key anymore using MD5.

With the Google Maps Android API, you can add maps based on Google Maps data to your application. The API automatically handles access to Google Maps servers, data downloading, map display, and response to map gestures. You can also use API calls to add markers, polygons, and overlays to a basic map, and to change the user's view of a particular map area. These objects provide additional information for map locations, and allow user interaction with the map. The API allows you to add these graphics to a map:

Icons anchored to specific positions on the map (Markers).
Sets of line segments (Polylines).
Enclosed segments (Polygons).
Bitmap graphics anchored to specific positions on the map (Ground Overlays).
Sets of images which are displayed on top of the base map tiles (Tile Overlays).
Maps are stored in SD Card.
Loads Faster

Step : 1
Before you start generate you API Key

Install Google Play Services in your SDK.

* click of the images to view larger

Step : 2
Import Google Play Service Library into your workspace.

Select File > Import > Android > Existing Android Code Into Workspace and click Next.
Select Browse..., Open <android-sdk-folder>/extras/google/google_play_services/libproject/google-play-services_lib and click Finish.

Step : 3
Create a new Project with GoogleAPIs.

Step : 4
Add Google_Play_Services as a supporting Library to the Project

Open "AndroidManifest.xml"

Add the following before closing </application>

REPLACE YOUR API_KEY

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="YOUR_API_KEY_GOES_HERE" />

Add following permission, changing your "Package Name"

    <!-- Change "vee.mapsv2.demo" with your package name -->

    <permission
        android:name="vee.mapsv2.demo.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="vee.mapsv2.demo.permission.MAPS_RECEIVE" />

    <!-- Change "vee.mapsv2.demo" with your package name -->

Add following permission, directly


    <!-- Access Internet -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

    <!-- External storage for caching. -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <!-- Location -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <!-- Maps API needs OpenGL ES 2.0. -->
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

Now "AndroidManifest.xml" should look like this


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="vee.mapsv2.demo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="17" />

    <!-- Change "vee.mapsv2.demo" with your package name -->

    <permission
        android:name="vee.mapsv2.demo.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="vee.mapsv2.demo.permission.MAPS_RECEIVE" />

    <!-- Change "vee.mapsv2.demo" with your package name -->


    <!-- Access Internet -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

    <!-- External storage for caching. -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <!-- Location -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <!-- Maps API needs OpenGL ES 2.0. -->
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <application
        android:allowBackup="true"
        android:hardwareAccelerated="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity android:name=".MainActivity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="YOUR_API_KEY_GOES_HERE" />
    </application>

</manifest>

Replace the below code in "activity_main.xml"

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"/>

Tasks Performed

✪ Check whether Maps is loaded or not
✪ Once Loaded, Add Marker at Custom "Latitude" & Longitude".
✪ Set the MapType
✪ Use CameraUpdateFactory to Move Camera & zoom to custom level.
✪ Retain current state on Orientation Change.

MapView has been deprecated, instead uses normal Activity.

Maps are encapsulated in the MapFragment class, you can implement them by extending the Android standard Activity class, rather than extending the MapActivity used in version 1.

Replace the below code in "MainActivity.java"


package vee.mapsv2.demo;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends FragmentActivity {
 GoogleMap map;
 double latitude = 12.971689;
 double longitude = 77.594504;

 LatLng latlon = null;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  latlon = new LatLng(latitude, longitude);
  setUpMapIfNeeded(); // Required to check the availability of Maps

 }

 @Override
 protected void onResume() {
  super.onResume();
  setUpMapIfNeeded();
 }

 private void setUpMapIfNeeded() {
  if (map == null) {
   /*
    * I avoid Crashing, if Google_Play_Services is not Updated or
    * Unavailable
    */
   map = ((SupportMapFragment) getSupportFragmentManager()
     .findFragmentById(R.id.map)).getMap();
   /*
    * To make sure map is loaded
    */
   if (map != null) {
    setUpMap();
   }
  }
 }

 private void setUpMap() {
  /*
   * Add a Marker Adding marker at 12.971689,77.594504;
   */
  map.addMarker(new MarkerOptions().position(latlon)

  /*
   * Add Title when clicked on marker
   */
  .title("Title")
  /*
   * Add Snippet when clicked on marker
   */
  .snippet("I am a looooooooooooooong Snippet"));

  /*
   * NormalMapView
   */
  map.setMapType(GoogleMap.MAP_TYPE_NORMAL); // Normal MapView

  /*
   * Move Camera to Snippet Location
   */
  float zoom = 11;
  map.moveCamera(CameraUpdateFactory.newLatLngZoom(latlon, zoom)); // toPosition,
                   // ZoomLevel
 }

 @Override
 protected void onPause() {
  super.onPause();
 }

How to View Source Code of an Android APK file - Part 2.

noreply@blogger.com (Awesome Idiot) — Sat, 12 Jan 2013 03:47:00 +0530

Am writing few words about viewing source code of an android app, to make sure this post appears in Google Search when you search for how to view source code of android apk or view source of apk, view android apk code and purely for nothing else, i am gonna add few more random keywords to make more visibility on android view source code of android apk, Google does not understand grammar, but searches for important keywords such as android, source code, java decompiler, axml printer, JDGUI, smali, which is related to this post, you are here cox i added these words,

when you reverse do reverse engineering for the first time, it will be lil difficult, later it's just a min of wrk. so don't skip any step, finish every step before you go to next one. Tanx for bearing with me. Lets go to the real post. :)

Every one who is reading this post is damn fckg intelligent, but every author has his own way of telling, so go step by step.

Step : 1 Download APK Tool (all OS) & "apk-install-windows" if you are using windows from Android-APKTool
Extract the two files in the same folder (APKTool) you should have the files like this
     APKTool
        |- aapt.exe
        |- apktool.bat
        |- apktool.jar

Step : 2 Download Dex-to-Jar Extract it.
           mirror : Dex-to-Jar

Step : 2a Download JD-GUI written by Emmanuel Dupuy
          mirror : JD-GUI

Step 3 : Download Android ADB

Step 4 : Connect your Mobile to PC with USB Debugging Enabled. How to Enable USB Debugging???

Step 5 : Open unzipped ADB folder, Press Shift + Right Click, anywhere in the folder. --> Select "Open Command Window here"

Step 6 : type

adb devices

You should see your device id. If you dont see some random letters, plz check whether you have connected properly.

Step 7 : type

adb pull system/framework/framework-res.apk

Step 8 :Copy the pulled framework files to APKTool Folder
If you have any issues pulling files, you can use my files >> framework.zip

Step 9 : Now, you should have the following in your APKTool folder

apktool if framework-res.apk

You might get an error

Exception in thread "main" brut.androlib.AndrolibException: Can't create directory
: C:\Users\VeeVee\apktool\framework
        at brut.androlib.res.AndrolibResources.getFrameworkDir(AndrolibResources.j
ava:663)
        at brut.androlib.res.AndrolibResources.installFramework(AndrolibResources.
java:558)
        at brut.androlib.Androlib.installFramework(Androlib.java:497)
        at brut.apktool.Main.cmdInstallFramework(Main.java:228)
        at brut.apktool.Main.main(Main.java:76)

Go to C:\Users\<username>\
Create New Folder Named "apktool" and inside apktool create new folder named "framework"

re-type :

apktool if framework-res.apk

Success if you get this message
I: Framework installed to: C:\Users\VeeVee\apktool\framework\1.apk
(This Step is one time Process only, you need not do this again & again)

Till now we were preparing for gathering reverse engineering apk tools

Let's start Ripping APK,
Copy any *.apk to APK tool folder.
Consider the apk name is "Sample.apk"

Step 11:
type :

apktool d -s -f Sample.apk

d --> Decompile
-s --> only xml
-f --> Force delete folder if already exists.

Step : 12
Open Sample Folder, Copy "classes.dex" to Dex2Jar folder,

Step : 12a
Type :

d2j-dex2jar.bat classes.dex

Step : 12b

Type :

ren classes_dex2jar.jar src_class.zip

Feeling Tough, Copy these files into "dex2jar" folder & just double click, skip 12a & 12b EVERYTIME :)

You will find src_class.zip file, copy src_class.zip back to SampleFolder in APKTool.

UnZip src.zip to src\

Open any file, i.e *.class inside src folder using JD-GUI

File --> Save All Sources --> src.zip

File --> Exit.

Delete Old classes.dex & src folder.
Unzip src.zip to src\

London 2012 Hurdles - The best ever Google Doodle for Olympics 2012

noreply@blogger.com (Awesome Idiot) — Mon, 6 Aug 2012 22:24:00 +0530

Everyone knows about Google Doodle, after the start of the Olympic Games this year, Google is displaying doodles everyday , this one is very exciting, Google Doodle made for hurdles, I played this game hell lot of times, every time it's very interesting, check out the video below. All you have to do is press forward & backward key alternatively, to jump use Up arrow key, complete the hurdle as fast as possible. To get 3Stars you have to finish within 13secs. Fastest finger wins.

Technical Stuff behind this game, It uses HTML5 tag named "Canvas"

<canvas style="position: absolute;" height="207" width="530"></canvas>

Image Format

data:image/png;base64

It means that the DATA inside the PNG image is embedded in the URL which is encoded in BASE64 format, this avoids http requests making no delay in loading the image.

This JavaScript >>> hurdle.js

"Beat my Time if you can"

If you wanna play this doodle you can play it here forever >> Google Hurdle
