While your trying to build and deploy your Xamarin Android solution, have you ever encountered an error such as,
Deployment failed because of an internal error: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
or with a similar error code as below?
If so, I should let you know, I’ve been there too!
This is usually because the last time you uninstalled your app from the emulator or device, you haven’t done it properly or something may have gone wrong during the uninstallation and some chunks of the old package is still lying around the system, therefore it preventing the reinstallation of your new package.
As the solution?
Therefore we need to completely uninstall the package manually through the adb command.
adb uninstall my.package.id
You must replace the my.package.id with your Xamarin Android app’s id.
And try again! Should be good to go! 😉
