Xamarin Forms “App Not Installed” Error After Uninstall & Reinstall of APK
Question
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.
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.

I had the same problem, and I found the solution here . Basically, Play Protect will not enable you to reinstall, even if it prompts you again. Disabling Play Protect solved it for me.

The solution from here worked for me:
- First change your build type to Release from debug.
- Clean Solution
- Rebuild Solution
- Right click your android project and click on archive
- After successful archive click on Distribute and click on Ad-hoc
- Create keystore file
- After finishing click on Open Distribution
- Your apk file is ready.
