title: ImageView lifetime in Android with Metaio
body: <p>Hello i've a cuestion with metaio in Android lifetime of the imageViews. How can i create an imageview (for example), and after three seconds get invisible or destroied? My images are in the xml file with gone visibility, and when you touch in a botton they come visible, but i want the image visible only for a few seconds.</p>
  
  <p>My problem is that i have a method where i want to show a shoot in the screen, and then, the shoot must desapear. I can't wait and after some seconds make visible because on metaio, render is in another place(I don't know where). My imageView is on xml but invisible.</p>
  
  <pre><code>public void onDisparo(View v){ 
      laser = (ImageView) findViewById(R.id.imageLaser);
      laser.setVisibility(View.VISIBLE);
      }
  
  }
  </code></pre>
