Unable to Import Existing Keystore

Rob Ward 1 Reputation point

Trying to distrubute/sign the apk and need to reimport my keystore. It doesn't show up anymore, not sure if it disappears because of the windows 11 update or visual studios updates, on 16.11.10. When I try to import it I get "There was an error import the key"

    Importing Keystore requires the key password and the keystore password, you could check all the input content is correct, and make sure this keystore file is correct( .jks file or .keystore file? ). You also try to update VS2019 to VS2022 to test. For more information, refer to https://learn.microsoft.com/en-us/xamarin/android/deploy-test/signing/?tabs=windows

    Upgraded to 2022 Enterprise. Got past the import keystore but now it fails when I try to distribute to google play. Get "Sign packages failed, Keystore was tampered with, or password was incorrect." I am pretty sure the password I have is correct, its in a password safe and hasn't changed for 2+ years.

    Try to delete the bin/obj folder and archive again. You could check the validity of this keystore by keytool. I'm not sure if your password has the symbols: @ ^ ] $, you could refer to this thread: https://github.com/xamarin/xamarin-android/issues/4036

Existing keystore doesn't seem to like my password. Ended up having to go back to an old jks keyfile that was converted years ago, it had a password with an @ symbol in it so changed the password on it and renamed the file to .keystore and it finally worked. Thanks for pointing me in the right direction.

    You are welcome. Would you mind converting it to an answer so that someone who has the same issue could refer to it?

    I couldn't get visual studio to import the keystore. But just moving the keystore files (keyinfo and keystore) worked. The files are in C:\Users<username>\AppData\Local\Xamarin\Mono for Android\Keystore<keyname>

      I think one of the reasons I had a hard time exporting was that the alias was not matching what I had in my notes. You can use the keytool to look into the keystore and see the alias name.
