My midlet seems to be too big for my phone. How can I make my JAR files smaller?
Obfuscation replaces the class and method names with short (1 character) names, which has the side effect of making the class files smaller. Originally obfuscation was intended to be a tool to make the reverse engineering of the midlet harder. One example of such tools is Proguard. If your application uses resource files (images, audio, or video), make sure they are optimized for the small devices (suitable bit depth, image resolution, audio bit rate, and so on.) You can also shave some bytes off your JAR-file by making the folder names really short.
