How to Uninstall Nokia Connectivity Framework (NCF?) - Cannot Install Nokia SDK 1.0 for Java

2011-09-02T01:21:00.001-07:00

My first attempt at installing Nokia SDK 1.0 for Java failed due to Avira AntiVir detected a malware on it, so I had to "ignore" the Malware and cancel the installation (which it seemed to not undoing it properly) and restart installation.

However the next installation failed while giving the following message:

Nokia Connectivity Framework(NCF) is already installed. Please uninstall NCF and press 'Ok' to proceed with installation.

At this point I am stuck. I've deleted the C:\Nokia\Tools folder entirely, and I can't find the "Nokia Connectivity Framework (NCF)" entry on "Add Remove Programs. There's not even a Cancel button (to close the installer) or Override button on this dialog box. Quite annoying. :-(

If you have a solution for this problem, please help.

How to Setup Qt Quick 4.7.3 / QML Project with Microsoft Visual Studio C++ 2008 Express

2011-08-06T18:58:00.001-07:00

It's possible to configure Qt Quick 4.7.3 / QML Development using Microsoft Visual Studio C++ 2008 Express project.

Quick Start

Install Microsoft Visual Studio C++ 2008 (Express)
Install Qt Library 4.7.x for Visual C++ 2008
Set environment QTDIR to C:\Qt\4.7.x

How to Create A New Qt Project in Visual Studio 2008

Create a new Makefile project
For Debug, set the build command as: qmake && nmake
Set the Debug launch command as: debug\YourApp.exe
For Release, set the build command as: qmake && nmake release-all
Set the Release launch command as: release\YourApp.exe
Add a YourApp.cpp file
Create initial Qt .pro project file by running: qmake -project

You should get this:

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

# Input
SOURCES += YourApp.cpp

You need to update this .pro Qt project file when you add source or header files.

A simple YourApp.cpp would be:

#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QPushButton hello("Hello world");
    hello.resize(100, 30);

hello.show();
return app.exec();
}

You can see how this simple Qt GUI application looks on the screenshot.

How to Add Qt Quick / QML Support

To support QML / Qt Quick, add to .pro file:

QT += gui declarative

Create the .qml file :

import QtQuick 1.0

Rectangle { width: 100; height: 100; color: "red" }

Then load the .qml file from the main .cpp :

#include <QApplication>
#include <QPushButton>
#include <QDeclarativeView>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

    QDeclarativeView view;
    view.setSource(QUrl::fromLocalFile("qmlvs.qml"));
    view.show();

return app.exec();
}

You can see how this QML / Qt Quick application looks on the screenshot.

What about Visual Studio 2010?

It's possible but you'll have to download Qt sources and
build using Visual Studio compiler which can take 3 hours or more.

Download / Clone Sample Projects from Git Repository

To make it easy for you, the sample projects are freely available as Apache Licensed open source projects in my Nokia Developer Projects Git repository:

NewsPopper - Read your favorite news sites and share them! [Early prototypes & sketches]

2011-06-21T23:16:00.001-07:00

With NewsPopper, you can get the latest news easily from favorite sites that interests you, and share among your friends.
Set up alerts so NewsPopper --as it name says-- will "pop" the news for you on your mobile device!
You can get notified when your friend comments on the news they read, or liked.

Sounds interesting ? It should :-)

It's a mobile application I'm currently working on. The app uses the latest powerful Qt 1.1 SDK and will run on all mobile devices that support Qt framework (which means modern Symbian S60, Symbian^3, Maemo/N900, and MeeGo devices like the upcoming Nokia N9/N950).

It will support touch and swipe gestures (on all touch devices and especially on the Nokia N9) and should be very user friendly from the first start.

The images shown are some sketches and how the current prototype looks.

When it's finished (hopefully!) you'll find it in an Ovi Store near you. :-)

I highly recommend you to get these resources to gain skills on Qt Development on desktop and mobile devices :

Nokia E5 Is an AWESOME Phone, But...

2011-03-10T22:42:00.001-08:00

I love my Nokia E5. It's reasonably priced, the keyboard is excellent, the feel and form factor is just great. BUT...

I'll try not to make this sound like bashing Nokia E5..although it probably is. It's definitely more about Nokia E5's software/OS that is Symbian S60 3rd Edition FP2... than it is about Nokia's hardware.

I have 3 "major" problems with Nokia E5 : (as you can see, they aren't destructive, but simply annoying)

SMS Alert Tone Sound Failure. After I reach about 1800 messages in SMS Inbox, my Nokia E5 won't alert me with sound. Practically the only way I can see if there are new text messages is by looking at the blinking keypad white light.
Screen dims under bright sunlight. I don't know if this is by (mal-)design or there is a setting that I mistakenly set, but it's very annoying that when I use my Nokia E5 under bright sunlight, the screen goes completely dark and I can't see anything. The phone UI itself is still working (invisibly) and when I press keys, it actually makes actions. Now it gets annoying and dangerous (e.g. I could mistakenly delete a message).
Exchange ActiveSync / Google Contacts regularly wipes my phonebook. This is probably more to do with Exchange ActiveSync than with Nokia E5 or Symbian, but I need this functionality to work well, because it's convenient for me to sync my Gmail address book with Nokia E5's phonebook (and I've been doing this since my BlackBerry days). However at times the sync will fail and it will wipe my Nokia E5 phonebook and for some time I'm left with completely empty phonebook before the next resync is successful. It's not dangerous, because all the data in Google Contacts is intact, but it's annoying because I have to re-specify default phone numbers and add members to groups all over again.

There are also slight annoyances :

Push mail / Nokia Messaging is not actively updating (i.e. "always on"). I'm not sure why it doesn't work now, but it did work a few months ago. I tried to set it to update a few hours, but it never updates unless I Synchronize ("Z") manually from Email. I also tried setting to "Always On", but it's never on... I'm using WiFi and most of the time I'm within WiFi area.
Email application in Nokia Messaging is slow. It's about an order of magnitude slower than my old BlackBerry Curve 8520's. From displaying a picture to composing it in an email takes about 5-10 seconds. After composing the email, sending it takes about another 5 seconds until it goes back to the previous screen. Email application is probably the slowest messaging application in Nokia E5, Contacts and Text Messages is sometimes slow (but usually just OK), and I have about 600 contacts and ~2000 text messages which I don't consider "huge" for today's smartphone standards (like Nokia E5).

Despite these shortcomings, Nokia E5 is still a great phone. Seriously. :-)

Being a Forum Nokia Champion again until 2012! :-)

2011-02-24T08:00:00.001-08:00

I got a really pleasant news from Forum Nokia tonight:

We are pleased to announce that due to your active participation in the field of mobile development and service to the Forum Nokia community in the past year, you have been re-selected to the Forum Nokia Champion program. Congratulations!

I'm currently the only Forum Nokia Champion from Indonesia, which is both sad (where's everybody?) and great (I'm special :-)

SMS Message Alert Tone not playing on Nokia E5

2011-02-09T20:35:00.001-08:00

I got the same problem again: SMS message alert tone is not playing on my Nokia E5. No sound at all, just the blinking light.

My previous suggestion, changing the home screen to another and then back, is not foolproof.

So I tried deleting messages fromSMS inbox and now it's working again. Right now I have 1825 messages and SMS alert notification sound is working. It seems the threshold is about 2000 messages and it starts to "silence" itself.

After deleting messages to about 1800 or under, if you still can't get SMS alert tone playing, restart the phone and then switch the home screen theme. It should work.

Qt Developer Workshop by Nokia - Bandung, Indonesia

2011-02-06T20:00:00.001-08:00

Forum Nokia invites mobile developers all around Bandung, Indonesia to attend Nokia-sponsored Qt Developer Workshop, held in Aston Primera Hotel, Pasteur, Bandung, Indonesia.

This session is presented by Eileen Khoo, Snr. Technology Expert at Nokia.

I met a few familiar faces, particularly smart people from ITB and iComm Bandung. Of course, ALL faces are familiar in some way in any developer event. ;-) (hint: it's not a Salsa dance course!)

How to Fix Nokia E5 Problem: Text/SMS Message Tone Not Working

2010-12-14T03:24:00.001-08:00

For the last few days (or weeks?) my Nokia E5 has an annoying problem: the text/SMS message tone is not played when receiving SMS. It won't vibrate either.

After searching through the Internet, seems like this has happened with other Nokia phones, especially Symbian S60 ones, like X6, E75, E72. I tried changing the message tone to Nokia default, but didn't work. I also tried deleting all text messages in my Inbox, but also didn't work.

I have restarted my phone numerous times.
I was about to reset my phone settings (by using *#7780#) but I remember something...

I once had a similar problem with email message tone. The solution was to change my home screen theme to 'Active'. My home screen was already 'Active', so I switched it to another home screen theme and tada! My Nokia E5 text message tone works again!

So, the solution is:
1. Go to Control Panel > Settings > General > Personalisation > Standby mode > Home screen theme.
2. Choose another theme. You can go back to your favorite theme after making sure the message tone works again.

Good luck!

Note: this bug dates back to around 2003 or probably earlier. Ironic that it still occurs with a modern 2010 device.

I'm Now Posting on Forum Nokia Blogs!

2010-11-30T07:05:00.001-08:00

Great news!

I'm now also posting articles on Forum Nokia Blogs titled Hendy Irawan on Mobile Qt.

I will still be posting here, though I'm not sure which articles should be on Forum Nokia and which ones should be here.

Or perhaps I will just cross-post. We'll see.

Anyway, it's good to have one more channel to share my experiences with Nokia, Qt and mobile applications development

fatal error: alsa/asoundlib.h: No such file or directory - building Qt Mobility 1.1.0

2010-11-29T10:56:00.001-08:00

If you get this error message while compiling Nokia's Qt Mobility 1.1.0 :

In file included from audio/qaudiodevicefactory.cpp:60:

audio/qaudiodeviceinfo_alsa_p.h:57: fatal error: alsa/asoundlib.h: No such file or directory

Sign Symbian/Qt SIS Apps with Qt Creator on Linux (Bonus: Qt+Qt Mobility Smart Installer for Nokia)

2010-11-28T09:15:00.001-08:00

The latest version of Qt Creator 2.0+ (included in Nokia Qt SDK) can now easily sign Qt/Symbian applications (.SIS files) with your Symbian Signed certificate and key files.

The best part of it is that it can also be used with Linux operating systems (e.g. Ubuntu). And you don't have to install Wine!
(See my previous article on how to use makesis.exe to sign SIS files on Linux for more details.)

To build a Qt/Symbian application on Linux and also sign the generated SIS file with your developer certificate and key, first you must install the Nokia Qt SDK Remote Compiler.

Open your Qt/Symbian project, go to Projects facet and add "Remote compiler" configuration.

Under Build Steps, expand "Compile at Server" details and you will see Sis Type and Symbian Signing settings.

There you only need to specify certificate file, certificate key file, and password/passphrase (if any).

As a bonus, you can not only sign the SIS file, but also automatically package it with Nokia Smart Installer!
Therefore, your Qt and Qt Mobility application now complies with Ovi Publish requirements and can be published to the Nokia Ovi Store! :-)

Signing Symbian/Qt Application in Linux

2010-11-28T04:29:00.001-08:00

Signing Symbian/Qt Mobile Applications conventionally has to be done on Windows.
The good news is now it's possible to sign Symbian/Qt mobile applications in Linux-based operating systems such as Ubuntu, with the help of wine.

First you need to get a Symbian certificate and key.
You can get your applications Symbian signed for free and get developer certificates from Ovi Publish.
Extract the signsis.exe file from this zip file.
Source: FExplorer thread
I recommend to make this file executable so you can run it directly with Wine and not having to prefix "wine" command for launching.
Running this command on Terminal:
chmod +x signsis.exe
Install Wine.
In Ubuntu, open Terminal and type:
sudo apt-get install wine

Now you can sign your unsigned SIS application files.

Type this command in Terminal:

wine path/to/signsis.exe <application-file.sis> <certificate.crt> <certificate.key>

If you make signsis.exe executable you can simply type:

wine path/to/signsis.exe <application-file.sis> <certificate.crt> <certificate.key>

Now you can sign any SIS file at will. :-)

For example in my system this is how it looks:

$ /opt/signsis/signsis.exe -s -v messagemerge_qt-4_6_3_m1_0_2_s60_3_1.sis messagemerge_devsigned.sis OVI_10-29-2010.crt OVI_10-29-2010.key

Nokia Qt SDK Remote Compiler - Available Environments

2010-11-17T10:49:00.001-08:00

Here are the list of build environments provided by Nokia Qt SDK Remote Compiler :

(see attached image)

It's pretty exhaustive. And covers about all the most common options (or *all* possible options???)

I've tried building with Qt 4.6.3 + Mobility 1.0.2 on Symbian 3rd Edition Feature Pack 1 and it builds fine!!! :-)

Really cool!

Installing Nokia Qt SDK Remote Compiler

2010-11-17T10:09:00.001-08:00

If you want to compile Qt Symbian/S60 applications on Linux/Ubuntu, you have to install Nokia Qt SDK Remote Compiler.

During Nokia Qt SDK installation, do not choose "Full", but choose "Custom" installation.
Then you can choose to install Experimental > Remote Compiler.

However, if you've already installed Nokia Qt SDK in "Full install" mode, you don't have to uninstall it.

On panel, click Applications > Programming > SDK-Maintenance-Tool
Now you can choose to install Experimental > Remote Compiler

Compiling Qt Symbian S60 applications on Ubuntu/Linux !

2010-11-17T10:03:00.001-08:00

I've just found a (very) hidden gem in Nokia Qt SDK : ability to compile/build Qt Symbian S60 applications on Ubuntu/Linux !

It uses a feature called Nokia Qt SDK Remote Qt Compiler.

Nokia Qt SDK has made it possible to simulate/run Symbian applications in a simulator (not emulator!) environment in Windows, Linux, or Mac OS X.

However, by using Nokia Qt Remote Qt Compiler, it's possible (and practical) to build Symbian/S60 applications on Linux/Ubuntu as well.
(Note that you still need to run the generated SIS files on a device, because Symbian/S60 emulator is not available for Linux, at least not with straightforward installation.)

I'm still on my way to installing the required stuff, but the steps are outlined here :

Installing Qt Mobility Final Libraries on Windows 7

2010-06-10T20:30:00.000-07:00

By following this article, you should be ready to develop Qt Mobility applications on Windows.

Note: This is only for Qt for Windows installation. If you want to develop Qt applications for Symbian on Windows, click here.

Install Qt SDK 4.6.3 + Qt Creator 1.3.1 for Windows.
Install Strawberry Perl for Windows (~ 32 MB). The reason why Perl is needed is covered in the later in this article.
Download Qt Mobility library sources.
Unpack Qt Mobility source distribution into a drive, e.g. C:\. This will create C:\qtmobility\qt-mobility-opensource-src-1.0.0
Launch Qt Command Prompt.
IMPORTANT: You cannot use regular Command Prompt!
Set the PATH to Strawberry Perl : (do not skip this!)
```
set PATH=%PATH%;C:\strawberry\perl\bin
```
Go to your Qt Mobility source folder and run configure:
```
cd \qt-mobility-opensource-src-1.0.0
configure
```
This will configure Qt Mobility build with default target directory: C:\QtMobility
Build Qt Mobility:
```
mingw32-make
mingw32-make install
```
Add C:\QtMobility\lib folder (the target folder) to your PATH environment variable (more on this below).
To add Qt Mobility documentation in Qt Creator: Go to Tools -> Options -> Help -> Add. Then browse C:\QtMobility/doc/qch/qtmobility.qch.

Now you're ready to develop with Qt Mobility on Windows. Check out Qt Mobility Quickstart App for an example.

Setting Environment Variables

In order to use Qt Mobility some environment variables need to be extended to locate the libraries, which are placed in the lib directory of the install path.

On Windows: PATH should be extended to include: C:\%TARGET_DIR%\lib

On my setup this folder is: C:\QtMobility\lib

PATH can be extended through Start -> Settings -> Control Panel -> System -> Advanced -> Environment variables. Under System variables, select "PATH", click "Edit..." and append your Qt Mobility lib folder.

Reboot your system to apply your changes to system environment variables.

You're now ready to develop Qt Mobility applications in Windows. :-)

How to Set Qt Application Icon and Title in Symbian S60

2010-03-30T21:05:00.001-07:00

Set Symbian S60 Application Title/Caption:

Alter project.loc file as necessary. Backup as project.loc.manual for future use (or if overwritten).
In Qt Creator, go to Projects panel. Remove QMake from Build Steps.
You can run QMake manually. Afterwards, replace the project.loc file with the one you backed up.

Set Symbian S60 Application Icon (in Launcher and in Task Manager):

Create icon using Inkscape or Adobe Illustrator. If using Adobe Illustrator, export directly to SVG-Tiny. Otherwise, export to SVG (Basic) format.
You need to convert SVG to SVG-Tiny format. Go to <S60 SDK>\S60tools\svg2svgt\installer and run the installer (SVG2SVGTConverter.exe) using the following settings:
- Compatibility: Windows XP Service Pack 3
- Run as administrator
Use the installed SVGT Tool to convert your SVG to SVG-Tiny format. Refer to this Forum Nokia Wiki article for more information.
Add the following to your project.pro : (make sure to use the SVG-Tiny file)
ICON = project-icon.svg

After changing your application icon, you may need to restart the phone to clear the icon cache so the updated icon will be shown. This problem happens at least in Nokia E71.

For detailed Symbian development resource, check out Developing Software for Symbian OS 2nd Edition (Symbian Press).

Update: Starting from Qt 4.7.2 (which is "currently unusable" for Symbian applications, since Ovi Store doesn't yet accept Qt 4.7 apps), QTBUG-13917 provides a better way:

If developer specifies "CONFIG += localize_deployment" in .pro file, the generated .loc and .pkg will now use translatable strings from .ts files defined in TRANSLATIONS. The .ts files must have an underscore and Qt language code at the end of the filename body to be compatible with deployment localization. E.g. myapp_en.ts.
Running lupdate will generate these entries into .ts files:

Application short caption

Application long caption

Package name

Smart installer package name

Debugging on Symbian S60 Nokia device with Qt Creator

2010-03-30T12:07:00.000-07:00

Qt Creator 1.3 and later provides support for Symbian S60 development (especially Qt apps, of course).

In addition to building for WINSCW (Symbian S60 Emulator) and GCCE (Symbian ARM target), Qt Creator also provides support for running and debugging Qt applications right on the Symbian S60 / Nokia device.

To debug/run Qt apps on Symbian S60 device:

Setup the Qt for Symbian development environment properly.
Install App TRK on your Nokia / Symbian S60 device.
Run App TRK and if configure it as USB. (Qt Creator currently only supports USB)
Connect your Nokia device to your computer. (make sure Nokia Ovi Suite / PC Suite is running)
Configure Qt Creator project to build using GCCE.
Configure Qt Creator project to run using "Symbian device".
Run/Debug your app from Qt Creator!

Troubleshooting

You may get stuck with the message "Waiting for App TRK to start on COMxx" during Run/Debug from Qt Creator:

The cause is because Qt Creator up to version 1.3.1 doesn't work well with high port numbers. This should be resolved in Qt Creator 1.3.2, but in the meantime there is a workaround:

Go to System -> Advanced Properties -> Device Manager.
Expand Ports, and double-click your Nokia device to bring the Properties dialog.
Click Port Settings tab. Click Advanced. And set the port to something to (COM1 to COM4 if possible).
Click OK on all dialogs.
Now disconnect and reconnect your Nokia/Symbian device. And you should be good to go.

For more information about Qt C++ development, check out C++ GUI Programming with Qt 4 (2nd Edition).

To learn Symbian C++ development, I recommend Porting to the Symbian Platform: Open Mobile Development in C/C++ (Symbian Press).
