title: Adobe Air Activate/Deactivate events doesn't work
body: <p>I can't get work Activate and Deactivate events for my Android Application. When I am running it on Windows it is working. </p>
  
  <p>In constructor of the document class I tried this:</p>
  
  <pre><code>NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE , onActivate, false, 0, true);  
  NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE , onDeactivate, false, 0, true);
  </code></pre>
  
  <p>and</p>
  
  <pre><code>this.addEventListener(Event.ACTIVATE , onActivate, false, 0, true);
  this.addEventListener(Event.DEACTIVATE , onDeactivate, false, 0, true);
  </code></pre>
  
  <p>and</p>
  
  <pre><code> this.stage.addEventListener(Event.ACTIVATE , onActivate, false, 0, true);
      this.stage.addEventListener(Event.DEACTIVATE , onDeactivate, false, 0, true);
  </code></pre>
  
  <p>this are the functions:</p>
  
  <pre><code>private function onActivate(e:Event) : void {
      new BubbleSnd().play();
  }
  
  private function onDeactivate(e:Event) : void {
      new AlertSnd().play();
  }
  </code></pre>
  
  <p>Why I can't hear the sounds on my phone? 
  When I press on home button, I deactivate focus so I should hear the sound...but nothing happends.
  I have used those Events few months ago on another Android App and then they works fine.
  Thank you!</p>
