title: Xamarin Forms "App Not Installed" Error After Uninstall & Reinstall of APK
body: <p>I have built an APK of an Android app which I created with Xamarin Forms. The APK works perfectly, but if I uninstall it and reinstall it, I get an error message "App Not Installed" upon trying to reinstall the APK.</p>
  
  <p>If I change the version number / version name and make a new APK, it can be reinstalled again successfully, but this means users can't simply uninstall / reinstall the same version of the app at will. How can I make it so it's possible to uninstall / reinstall the same APK successfully? Thank you.</p>
