Android NDK sample framework: screen turns black upon GLContext swap: EGL_BAD_SURFACE: err=12301

[Chuck Moyes]

My Android NDK app is returning a bunch of EGL_BAD_SURFACE: err=12301 upon Swap as follows from the sample framework:

EGLint GLContext::Swap()
{
    bool b = eglSwapBuffers( display_, surface_ );
    if( !b )
    {
        EGLint err = eglGetError();
        if( err == EGL_BAD_SURFACE )
        {
            LOGE("Swap: Re-creating egl context EGL_BAD_SURFACE: err=" + std::to_string(err));

            //Recreate surface
            InitEGLSurface();
            return EGL_SUCCESS; //Still consider glContext is valid
        }
        else if( err == EGL_CONTEXT_LOST || err == EGL_BAD_CONTEXT )
        {
            LOGE("Swap: Re-creating egl context EGL_CONTEXT_LOST || EGL_BAD_CONTEXT: err=" + std::to_string(err));

            //Context has been lost!!
            context_valid_ = false;
            Terminate();
            InitEGLContext();
        }
        return err;
    }
    return EGL_SUCCESS;
}

Whenever this happens, the screen flickers black color or turns black completely. It happens intermittently on Samsung Galaxy S6 edge.

Somebody sent same issue on the device and it looks like an app is receiving APP_CMD_LOW_MEMORY callback in the situation.

Are you experiencing the same issue?
