Thank you Julius, Unfortunately, I cannot it get it work as I use the emulator (SDK 1.5 r1) (and do not have any device)
The emulator does not handle the transparency format (http:// groups.google.com/group/android-developers/browse_thread/thread/ 7d18f1b3480ff242) I only get a blank screen with a small part of the screen below showing the camera preview. Did anyone try on older version of the emulator ? If it works fine on devices, I can still work on it disabling temporary the line: mGLSurfaceView.getHolder().setFormat (PixelFormat.TRANSLUCENT); And enabling it when I plan to distribute it on devices...
