Android Xamarin C#: App Runs In Emulator But In Actual Device Gets Error: [install_parse_failed_bad_manifest]

My app runs perfectly in the android emulator but when I try to deploy in debug configuration it fails and tells me this: 3>:Deployment failed 3>Mono.AndroidTools.InstallFail

Solution 1:

I've had similar sorts of errors occur when trying to debug after installing a release version.

The fix was to manually uninstall the app via the app manager on the device first.

Sometimes it shows up in the app manager under the namespace only rather than the application name.
