title: Install .apk without Activity or Dialog
body: <p>My app downloads an .apk and installs it using an activity like this:
  <a href="https://stackoverflow.com/questions/4967669/android-install-apk-programmatically">Android: install .apk programmatically</a></p>
  
  <p>However, it causes a dialog to appear and requires user action. So my question is:</p>
  
  <p>Is there a way to programatically without requiring user interaction?</p>
  
  <p>Based on the comments I have to provide additional information:</p>
  
  <ul>
  <li>Yes, there are security implications. I just want to know if it is possible. </li>
  <li>Actually, I do own their phone.</li>
  </ul>
