Drawing to the Screen Using the Graphics Context BlackBerryDevelopment

Wed, 11 Apr 2012 03:14:04 GMT

The basic interface for displaying anything to the BlackBerry device's screen is the net.rim.device.api.ui.Graphics class. It's used under the hood by pretty much all elements of the BlackBerry user interface, and it gives you the tools to do anything you've seen in any BlackBerry application's user interface. If you're going to be doing any kind of user interface work with BlackBerry applications, you should get very familiar with the Graphics class. Each instance of Graphics is associated...

Adding a Header Background BlackBerryDevelopment

Mon, 13 Feb 2012 10:32:59 GMT

We want to put a black background behind the header image and align the image to the left. The second change is easy simply change the style Field.FIELD_HCENTER to Field.FIELD_LEFT or leave it out entirely, as FIELD_LEFT is the default . To make the image sit on a different color background, we'll put the BitmapField inside another manager and let that manager draw the background color. We'll use a HorizontalFieldManager. This first part should be familiar to you by now. Change the following...

Whats Different About Developing for BlackBerry BlackBerryDevelopment

Sat, 11 Feb 2012 21:46:29 GMT

If you're familiar with developing for modern desktop PCs or servers, there are many things you might not think about before starting to develop for BlackBerry. Of course, every platform is different, but there are some things to keep in mind when designing and implementing an application for BlackBerry. Generally, BlackBerry CPU speed and RAM - as with most mobile devices - lag a few years behind average PCs. The latest BlackBerry devices are getting faster, so this isn't as much of a...

Use socket connections Blackberry Java Development

Mon, 30 Jan 2012 04:28:33 GMT

Although you can implement HTTP over a socket connection, you should use an HTTP connection for the following reasons Socket connections do not support the BlackBerry Mobile Data System features, such as push. Applications that use socket connections typically require significantly more bandwidth than applications that use HTTP connections. Before opening a socket connection, verify that the BlackBerry device is in a wireless coverage area. Use the CoverageInfo class and CoverageStatusListener...

Making Secure HTTP HTTPS Connections BlackBerryDevelopment

Fri, 06 Jan 2012 12:46:39 GMT

To make a connection to a secure HTTP server, replace http with https in the Connector.open method. Fortunately, the web application also supports HTTPS connections, so simply substitute https into the URL to make and then click Get. The result will look almost the same as the non-secure HTTP connection see Figure 7-14 . Figure 7-14. Retrieving the web application over HTTPS Figure 7-14. Retrieving the web application over HTTPS Performing the POST works in a similar way. We haven't had to...

Hello BlackBerry BlackBerry Games Development

Mon, 26 Sep 2011 19:24:35 GMT

In this section, you'll see the basics of how RIMlets work by creating a Hello World'' RIMlet. Note The term RIMlet is an informal name that you'll see in discussions on the Internet, but it doesn't appear in RIM's official documentation. As you'll see in the sections on compiling and building your application, RIM uses the term CLDC application for BlackBerry applications that aren't MIDlets. This choice of terminology is confusing because a MIDlet is also a type of CLDC application. Since...

Listen to Me BlackBerry Advanced APIs

Mon, 26 Sep 2011 12:33:45 GMT

The five states give a big picture of what your media is doing, but sometimes you'll want more granularity than that. It might be nice to know when you have recorded 30 seconds of audio, or when a stream has run out of data and needs to buffer. RIM supports these use cases by offering a standard listener interface. By implementing PlayerListener, your application can register with a Player instance, as shown in Figure 2-3. PlayerListener defines a single method, playerUpdate , which will be...

Manage foreground events BlackBerry Application Developer Guide

Mon, 26 Sep 2011 09:23:47 GMT

The system calls Application.activate when it brings an application to the foreground. Most applications do not need to override activate . Applications should perform any initialization, including any required UiApplication.pushScreen calls, in the application constructor. Because activate can be called multiple times for the same application, applications should not perform a one-time initialization in this method. An application can override activate to perform additional processing when it...

Delegate Managers BlackBerryDevelopment

Mon, 26 Sep 2011 09:00:41 GMT

A screen doesn't directly lay out any of its fields. Instead, it delegates that to a manager that's specified when the screen is instantiated. All the manager methods on the screen add, delete, insert, etc. actually end up invoking the same methods on the delegate manager. The only component the screen handles directly is the delegate manager. This separation of manager and screen makes it easy to change the internal layout of any screen. This also means that a screen must have a delegate...

Display stack BlackBerry Application Developer Guide

Sun, 25 Sep 2011 20:57:37 GMT

Screen objects are maintained in a display stack, an ordered set of Screen objects. The screen at the top of the stack is the active screen that appears to the user. When an application displays a screen, it pushes the screen to the top of the stack. When an application closes a screen, it pops the screen off the stack and displays the next screen on the stack, redrawing it as necessary. ONote Each screen can appear only once in the display stack. The VM throws a runtime exception if the same...

Recording Audio BlackBerry Advanced APIs

Fri, 23 Sep 2011 20:31:56 GMT

By now you should have a general idea of how the recording process works. You will request a Player, configure it for your desired capture, start it to begin recording, and then stop it once the recording is complete. At that point you can retrieve the recorded audio data. Before you start, though, you should ask yourself whether you care what format that data will be in. RIM offers several choices for audio encoding. Your choices are described in Table 2-3. Note that each choice has a required...

MediaGrabber's simple UI can be run on a wide variety of devices without requiring changes to the code. By using the CLDC UI framework, the same code works fine on touch-screen and QWERTY devices. Throughout the book, I have been careful to test for feature support within the app, so no extra work is required to support the presence or absence of a camera or other piece of hardware. MediaGrabber does make use of APIs from version 4.5, but none from later OS versions. It seems reasonable to...

Protecting a StandAlone BlackBerry BlackBerryHacking

Connection Method Using Direct TCPIP Instead of BESMDS BlackBerryDevelopment

Thu, 22 Sep 2011 02:29:22 GMT

Now, let's take a few minutes to see how to force a connection to make a direct TCP IP connection to the server instead of using the BES MDS. The Networking application currently uses the device's default connection method. As mentioned earlier, if you run the application on a device that's not activated on a BES, the requests will already go over direct TCP IP. However, if you run on a device connected to a BES, the POST and GET requests are done through the BES. To force them to go directly,...

Understanding BlackBerry Application Files BlackBerry Games Development

It's the file containing the resources and compiled class files to run on the device. It's a standard Java Archive file with the added requirement that the manifest file META-INF MANIFEST.MF in the JAR file has...

Intercepting BlackBerry Communication BlackBerryHacking

Wed, 21 Sep 2011 13:39:45 GMT

Most BlackBerrys come equipped with a 3G mobile-data wireless-connectivity interface, such as EvDO. In addition, most have Bluetooth capability and some even have Wi-Fi capability. It is important to realize that these interfaces are actually transmitting data to and from the BlackBerry device. This data could be sensitive and needs to be protected. Not all of these interfaces transmit data in a linear fashion. The data does not go directly from point A to point B. Rather, the data is like a...

Google maps use a Mercator cylindrical projection to flatten the earth's surface onto a 2D map, as illustrated by Figure 11-12. Longitudes are mapped linearly to the x-axis, but latitudes are increasingly spaced out the further they are from the equator. This increasing distortion means that Google Maps only utilizes the Mercator projection between latitudes 85.05113 degrees north and south, which explains why some parts of the polar regions are missing in Figures 11-8 and 11-12.
