title: How can we install/Push the Android application over proprietary Wifi Network?
body: <p>We are developing an android application which is to be installed on the ~500 devices in the premises.How can I do it centrally at one go via wifi network. </p>
  
  <p>Thrice every quarter, the following is required</p>
  
  <ul>
  <li>The application (upgradeable version) needs to be installed.</li>
  <li>Uninstalled (older version) frequently.</li>
  </ul>
  
  <p>I know on device we can set <strong>"allow unknown sources"</strong> by default. But is it possible to push/install the application (like the ICS push on the Ginger Bread Mobile Phone recently)</p>
  
  <p>I have gone through this <a href="https://stackoverflow.com/questions/4522630/non-market-content-publishing">post</a> but no precise answer.</p>
