Hi!

I have written a small OpenGL application.
Running it on the emulator works just fine. I can see my object.
But running the same application on device, causes a black screen. I can't see any errors.
Running the adb logcat, I see this message.

W/ActivityManager( 54): Launch timeout has expired, giving up wake lock!
W/ActivityManager( 54): Activity idle timeout for HistoryRecord{43b45ec8 {org.example.opengl/org.example.opengl.OpenGL}}

What does this mean?

What can I do to try to solve my problem.

I think I found the problem

commenting out this line in my code: gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
Fixed the problem

I'm not using textures at this moment. Maybe that's why it gets black on device.
Probably the emulator is running the Sofware version of Opengl.. but device is running the hardware accelerated one.
