JAVAFX on ANDROID

Mon Oct 14 04:45:56 PDT 2013

Hi Tomas,

never mind, I found the problem over here in the simulator ;) I had to activate the GPU support.

So, now I had to BGRA image format for Android and now I get JFX up and running without fonts.

There are two things missing:
1. fonts        - here we probably need to get pango working for Android right?
2. touch events - I saw that you have got a special Android proxy for the input stuff Java_com_oracle_dalvik_FXActivity_00024InternalSurfaceView_onTouchEventNative
This seems to crash for some reason. any idea? It's not that complicated but it is producing a stack trace.

After fixing the touch events Brickbreaker with Niklas' no-font-patch should work. I'd pleased to test this.

kind regards
Matthias
