Question

I’m using https://github.com/markfguerra/GLWallpaperService/ to make an android live wallpaper.
I’m trying to load a png file as fullscreen background, however currently all I get is a black screen.

I’ve searched for a few days now but still haven’t found out the problem.
I’m doing the following:

public void onSurfaceCreated(GL10 gl, EGLConfig config)
{
        gl.glEnable(GL10.GL_TEXTURE_2D);
        gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
        gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
}

and every frame:

public void onDrawFrame(GL10 gl)
{
        Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.target00074);
        int[] textures = new int[1];
        gl.glGenTextures(1, textures, 0);
        gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]);
        GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); 
}
