So, I published my game to playstore several months ago, back than I signed it with a keystore and I made backup of that keystore. Now, I made update for my game, and when I try to upload it onto Playstore, it says that my APK on the playstore is differently signed than the one I am trying to upload. It says that the certificates are different, SHA1 exatcly. I double checked and I am 100 % sure that I am using same keystore because it has the name of my app, and I know that I saved it there, onto my USB flash drive back up. Then, I downloaded some software to check my keystore, and when I open its details it really gives me different SHA1 certificate than one on the Playstore. So now I cannot update my app. Please help.
I have this problem!!
