I get the following error occasionally and have a quick workaround I’d like to share, for physical device debugging only.
Error ADB0030: Mono.AndroidTools.RequiresUninstallException: The installed package is incompatible. Please manually uninstall and try again.
at Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess(String output, String packageName)
Disconnect your Android device, uninstall your app, reboot your Android device, then connect your Android device and try debugging your app again.
It’s simple but it works!
If you’re debugging over Wi-Fi and experience this error please reach out and let me know if you’ve found a workaround.
