title: How to put an AVD (emulator) into OFFLINE mode?
body: <p>I would like to test the behavior of my application when the user is in a no-signal zone or when his phone is in flight mode.</p>
  
  <p>-> <strong>How do I put an Android Virtual Device into offline mode</strong> (where no connection to the internet is possible) ?</p>
  
  <p>I have tried the following:</p>
  
  <ul>
  <li><p>Activating flight mode via the AVD settings: surprisingly, this does NOT work (browsing  the internet is still possible in flight mode!)</p></li>
  <li><p>Disabling the network connection on my PC: this obviously works, but is not satisfactory as I need Internet when I am testing my app</p></li>
  </ul>
