title: Xamarin Android install flags
body: <p>I'm building an Xamarin android admin app meaning that the app will be the device admin but in order to be able to uninstall the app while developing I need to add to the android manifest <code>android:testOnly="true"</code> 
  but then it fails at deployment I get the following error</p>
  
  <pre><code>Mono.AndroidTools.InstallFailedException: Failure [INSTALL_FAILED_TEST_ONLY: installPackageLI]
  </code></pre>
  
  <p>and to avoid that error I need to pass an install flag with adb as written this <a href="https://stackoverflow.com/questions/25274296/adb-install-fails-with-install-failed-test-only">stack overflow answer</a></p>
  
  <p>how do I do that in VS.</p>
