Android keystore stopped working

Question

Just recently I have had a problem with a key store. I know there are plenty of questions about this problem already. I have read them all and Googled furiously.

Answer 1

Just had this issue - all of a sudden Android Studio forgot my passwords and wouldn't use the ones I had in the gradle file. I've had the same keyfile and passwords in the same project for 6 years!

So I entered them manually - but it failed verification time after time. I tried some things like invalidating caches, restarting Android Studio and restoring a backup of the keystore but nothing helped.

Finally in pure desperation I tried to switch the keystore password and the key password. Lo and behold - it worked! Turns out I had switched the passwords when I entered them into the Gradle build file a few years ago, and for some reason I never noticed.

Conclusion: never be 100% sure that you're doing it right.
