The message for me is very clear: jarsigner error: java.lang.RuntimeException: keystore load: Keystore was tampered with, or password was incorrect

So either your keystore file is invalid or the password you used is incorrect. Check again and see if it’s properly configured in the settings (Editor settings for debug keystore or Export dialog for release).

I’m hitting this error as well. I agree that the error is self explanatory but from what I can tell, my keystore appears to be valid and the password works.

I tried to verify it with

keytool -list -v -keystore someprojectname.keystore

Which did produce keystore information after entering my password.

Am I validating the keystore incorrectly or is there anything else you can think of that will help me narrow down the problem?

For reference, I’m following the steps located here:
