2.0

here is the createBuffer() method in MyRenderer class:

public void createBuffer(){
Log.e("Creating buffer 5" , " ");
fb = new FrameBuffer(320, 480); // these values are just for now
Log.e("Buffer created " , " ");
}
maybe this can help :

sorry I am answering so late.

The problem is resolved, i created new project, upgraded to the newest jpct (1.25) and it is working again 

Thanks both of you 

Yes i have.
that is the whole code i am doing with the mGLView:
mGLView = new GLSurfaceView(getApplication());
mGLView.setEGLContextClientVersion(2);
mGLView.setEGLConfigChooser(new AAConfigChooser(mGLView));
renderer = new MyRenderer();
mGLView.setRenderer(renderer);
mGLView.setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
setContentView(mGLView);
and here is the FrameBuffer code initialization:
fb = new FrameBuffer(w, h);
Previously the AA was working on emalutor and also on the Samsung galaxy Ace device, but now it is not working on either of them. In emulator I am using android 4.1, which has support of OpenGL ES 2.0 on emulator, here is a log of it:
09-13 09:18:44.319: I/jPCT-AE(935): GL20 render pipeline initialized!

I tried to create new emulators, i restored the older version of my app where the AA might have been working, but nothing worked, i still keep getting "No AA enabled!"

I really don't know what else should i try 

Hi,

I am trying to enable AA in my game on Android. I am doing it this way:
mGLView.setEGLContextClientVersion(2);
mGLView.setEGLConfigChooser(new AAConfigChooser(mGLView) {
public EGLConfig chooseConfig(EGL10 egl, EGLDisplay display) {
int[] attributes = new int[] {EGL10.EGL_BLUE_SIZE,8,EGL10.EGL_RED_SIZE,8,EGL10.EGL_GREEN_SIZE,8, EGL10.EGL_DEPTH_SIZE, 16, EGL10.EGL_NONE };//EGL10.EGL_DEPTH_SIZE, 16,
EGLConfig[] configs = new EGLConfig[1];

int[] result = new int[1];
egl.eglChooseConfig(display, attributes, configs, 1, result);
return configs[0];
}
});
and in LogCat i found this:

09-12 09:35:09.637: I/jPCT-AE(1267): No AA config found...defaulting to non-AA modes!
09-12 09:35:09.637: I/jPCT-AE(1267): No AA enabled!

As you can see i have enabled OpenGL 2.0, so i don't know what could be the problem.

Thanks for any help

i solved it, the problem was in my calculations, i had one vector normalized, if i removed this normalization, it works now.

I have one more question. My physics almost works perfectly, when the ball hits the wall it reflects as it should, but when the ball is rolling on the wall (so it touches the wall, and there are many collision events) than the speed of the ball is bad, it is because on each hit of the wall the speed of the ball is reduced. How should i distinguish if the ball is just rolling on the wall(so that there are many collision events) or if the ball hits the wall just one time and reflects away? I have been thinking a lot about it, but i can't find any solution how to distinguish it.

Thanks for any help.

EDIT: Problem solved, problem was in reflection vector. Thanks for your help EgonOlsen 

Thanks for the answer, now it works great. But i realized that the most suitable detection method for my game is the Sphere-Polygon method. I have already implemented this method and it works, now i just need to know the angle between the colliding objects to calculate the my physics. I tried to use the SimpleVector which gave me the checkForCollisionSpherical() function and  to calculate the angle from this vector, it gives me some angle but it is pretty inaccurate sometimes. Is there another way to calculate the angle between tho colliding objects?

Thanks for the reply
