JAVAFX on ANDROID

Mon Oct 14 03:17:52 PDT 2013

Hi Tomas,

since Tobi told me he had a similiar problem in the first place with the iOS port and he managed to run JFX8 without font.
We deactivated fonts. There is some code to deactivate and after that it looks like it is starting the JFX-Application.

I track the error down to, compileShader in ES2Shader.java on line 130. This is returning 0 from native code. 
The native codes looks okay for me and the Android Simulator is supposed to emulate OpenGL ES 2.0 correclty, so I am not sure
why the compileShader returns 0...

 	int vertexShaderID = glCtx.compileShader(vert, true);
        if (vertexShaderID == 0) {
            throw new RuntimeException("Error creating vertex shader"); //<<--- this Exception occours.
        }

I know this is the common error from the shader compiler, but this should have worked for you, 
when you started your own application. Do you have a hint, what I could have been done wrong?

I assume right now that the native build is correctly, since it is called from java and it does 
return the correct EGLContext. This assumption might be wrong.

regards
Matthias
