If ant is let loose on backends/platform/android it copies everything it can into the final apk file, which we obviously don't want. This changes it so that it will only see the java files which it compiles puts the results into the apk.
Touching and holding the left side of the screen functions as a
joystick.
Swiping the middle side allows fine control over arrow keys (eg.
dialogues), tapping it sends an enter key.
Swiping the right side up/down sends pageup/pagedown.
Android NDK 5 and SDK 7 (Android 2.1) are needed to provide full multitouch support. Otherwise MotionEvent.getPointerCount() and MotionEvent.getX(int) are not available.
In addition GLES2 headers are only available in Android 2.1 and newer revisions.
Do not compress zip-files added to the apk archive. This is very slow on android 2.3 devices if the zip-file is big (e.g. modern.zip theme) and devices with android < 2.3 do not support assets with an uncompressed size greater than 1 MB at all.
As most zip-file entries (like themes) are just stored and not compressed, zip-file assets are recompressed before adding them to the apk to avoid wasting space.
