OnDrawFrame not called on Android

I got a problem when the rendering object doesn't call it at all onDrawFrame. The debugger never hits the breakpoint inside the function. So my square is not drawn. Here is the code, let me know if you need anything else:

public class renderer implements GLSurfaceView.Renderer {

Square square;

public void onDrawFrame(GL10 unused) {
    GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
    square.Draw();
}

public void onSurfaceChanged(GL10 gl, int width, int height) {
    GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
}

public void onSurfaceCreated(GL10 unused, int width, int height) {
    GLES20.glViewport(0, 0, width, height);

}

public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    square = new Square(5, 5);

}

Primary occupation:

public class gameActivity extends Activity {
/** Called when the activity is first created. */

private GLSurfaceView mGLView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    staticHolder.context = getApplicationContext();
    mGLView = new GLSurface(this);
    setContentView(mGLView);
}
@Override
protected void onPause() {
    super.onPause();
    // The following call pauses the rendering thread.
    // If your OpenGL application is memory intensive,
    // you should consider de-allocating objects that
    // consume significant memory here.
    mGLView.onPause();
}

@Override
protected void onResume() {
    mGLView.onResume();
}


class GLSurface extends GLSurfaceView
{
    renderer r = new renderer();
    public GLSurface(Context context)

    {
        super(context);

        setEGLContextClientVersion(2);
        setRenderer(r);
        setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
    }
}

}

Currently, the screen is just black. Is there any idea why openGL is not showing correctly?
