title: Why launch intent in WallpaperService not working?
body: <p>I looking for help with my Live Wallpaper. I wanna open Url and open calculator when i click on polygon. 
  I have permission for that in Manifest: android:permission="android.permission.BIND_WALLPAPER" 
  and this.setTouchEventsEnabled(true); in onCreate.
  Why is it not working ?</p>
  
  <p>There is my code:</p>
  
  <pre><code> public void onTouchEvent(MotionEvent event) {
          if(event.getAction() == MotionEvent.ACTION_MOVE){
              mTouchX = event.getX();
              mTouchY = event.getY();
          }else {
              mTouchX=-1;
              mTouchY=-1;
          }
  
          com.snatik.polygon.Point point  = new com.snatik.polygon.Point(mTouchX,mTouchY);
          if(polygon1.contains(point)){
              Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.wp.pl"));
              intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
              startActivity(intent);
  
          }
  
          if(polygon2.contains(point)){
              Intent intent = new Intent();
              intent.setAction(Intent.ACTION_MAIN);
              intent.addCategory(Intent.CATEGORY_APP_CALCULATOR);
              intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
              startActivity(intent);
          }
          super.onTouchEvent(event);
      }
  </code></pre>
