Java - Code examples

Frozen Bubble

This Java ME example application demonstrates how you can port a full-screen game from Android to Java ME in Series 40 touch devices. In this port the same game logic code and most of the resources were reused while new code was written for starting up the game, handling menus, and playing sounds. The code is based on the Android version of Frozen Bubble, created by Pawel Aleksander Fedorynski. The Java ME port, just like the original Frozen Bubble, is covered by GNU GPL v2.
