    Hi all,
    I'm trying to follow the instructions on the android developer's site for opengl-es20
    ( I can't post links yet since i'm a newbie ... :))

    I have created everything accroding to the instructions and as far as i can see i have the exact identical code to the one displayed in the html.

    When I try to activate the application - I get a message box :
    Sorry !
    The application HelloOpenGLES20 (proccess pack.HelloOpenGLES20) has stopped unexpectedly. Please try again.
    and a "Force close" button.

    I did try to debug the app with eclipse but couldn't understand what seems to be the problem.

    Any ideas will be great ...

    Thanks,
    Ohad.

    just giving this error won't help
    turn to the DDMS tab in eclipse, and check the logcat in there to see exactly what's causing the crash
