title: Android uninstall device administrator using adb
body: <p>I have installed quick heal mobile security on my android device(Micromax Canvas A110) android version 4.1.4. I am trying to uninstall it, but not able to do so. After further googling, I found out that we would have to deactivate it from device administrator menu in settings.
  I tried doing it, only to find that the window with options "cancel" and "deactivate" does not go away on clicking the "deactivate" button.</p>
  
  <p>I tried to uninstall the app using the <code>adb uninstall</code> command after finding out the installed packages using: <code>adb shell pm list packages</code> which gave quick heal's package name as <code>com.quickheal.platform</code>.</p>
  
  <p>But <code>adb uninstall com.quickheal.platform</code> command gives <code>Failure</code></p>
  
  <p>So how do I do it using adb?</p>
