Android: Nullpointer Exception In Addongestureperformedlistener

public class TestActivity extends Activity implements OnGesturePerformedListener { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedIns

Solution 1:

if you are sure you have a View with @+id = "gestureOverlayView1" inside your main.xml layout, then try

gestures.addOnGesturePerformedListener(this); 

instead of

gestures.addOnGesturePerformedListener(TestActivity.this);

(remove the TestActivity specifier from this)
