Debugging MIDlets on the MOTOSLVR L7 | October 31, 2007
Debugging is the process of locating and fixing errors in a program's source code. Debugging projects that run on mobile devices are very similar to debugging projects that run on desktops. However, because the processor on which the debugging takes place is in an external device and not in your computer, the connection between device and computer plays a vital role in on-device debugging. This article describes several methods for debugging MIDlets using the Motorola SLVR L7 as the target device.

Nearly all current Motorola handsets have built-in cameras with the ability to take pictures and record video. Java application developers are discovering increasingly clever uses for these ubiquitous cameras, using the Mobile Media API detailed as a component of JSR-135. This article provides a quick and practical guide to leveraging Java ME APIs to take pictures and record videos within applications, along with a handy troubleshooting section and sample code.

A Java ME application (MIDlet) comprises two files – A JAR file (Java Archive) and a JAD (Java Application Descriptor) file. The JAR file is a ZIP file used to distribute a set of Java classes. It stores compiled Java classes and associated metadata that can constitute a program. The JAD file is the description file for the MIDlet application containing text attributes which describe the application and its capabilities. This article gives a detailed and complete attribute list that can be used in the JAD file, which includes custom Motorola JAD attributes. These attributes are used to retrieve and install a MIDlet application and they describe the requirements of the MIDlet.

In Java ME devices, processing speed and memory space are limited; performance improvement makes the application run in a fluid and robust way. This document includes two parts: an introduction to Motorola SDK’s profiler and performance improvement tips.

Loading ready-made pieces of 3D content from an M3G file is generally the most convenient way for an application to create and populate a 3D scene. The M3G file can be created easily using graphic design tools such as 3DMax, so as a developer, you only need to focus on implementing those 3D objects. This article will give developers guidance on implementing ready-made 3D objects to create 3D applications.

In a previous article on using JSR 75, we described application development for a phonebook on the handsets represented in the A.4 and A.3 emulators using the JSR 75 PIM API implementation. This article is extension to that previous article, and describes various features and differences of various JSR 75 PIM-based implementations across Motorola OS handsets.

MIDP 2.0 provides the functionality to process pixels in an image. Using this functionality, we can manipulate images more conveniently by adjusting transparency, semitransparency and opaqueness. This article demonstrates how to use pixels to manipulate transparent images in a MIDlet. It also provides sample code and information about image transparency implementation on Motorola handsets.

The Holy Grail in many enterprise applications resides in the ability to synchronize Personal Information Management (PIM) data from one device to another over an established network connection. This article shows how JSR 75 can be used to build a phonebook application on a Motorola handset, targeting devices categorized in the A.4 emulator.

Creating applications that have a small footprint is key in developing for mobile devices. What happens when you depend on using large amounts of user-supplied data, though? The answer, of course, is auxiliary storage in the form of SmartMedia, CompactFlash®, Secure Digital and Multimedia Cards, or even a Memory Stick®. Allowing access to these storage media, then, is as important as that light footprint for your application. This technical article gives readers the details they need to allow mobile applications to leverage the power of add-on storage in Motorola handsets.
