To my understanding, when posting to the Google Play a keystore is required and if it is lost or the password is forgotten, then no updates to the app can be made.
I am working on a small team that previously had 1 android developer. Now we have new android developers. I still have access to the old developer's computer and but need to allow the new developers to be able to upload new apk's to the Google Play store to update the app.
When I try to drag a new apk into the Google Developer Console, I get this error:
Upload failed
You uploaded an APK that is signed with a different certificate to your previous APKs. You must use the same certificate. Your existing APKs are signed with the certificate(s) with fingerprint(s):
[ SHA1: AO:1E:28:4L:R7:8N:DN:M8:FF:B0:GHB:AA:68:Y5:7C:F6:43:62:15:0A ]
and the certificate(s) used to sign the APK you uploaded have fingerprint(s):
[ SHA1: Z1:4X:4Y:AG:F4:BF:G8:44:DD:7A:E3:CG:2Y:25:E6:3P:9O:B3:DG:51 ]
To resolve this I believe I need to get the certificate file off of the computer that currently is still able to build apk's and post to the google play store (as noted here). The file I need must be on old developer's computer somewhere, since old developer's computer is still able to build an apk that is accepted by google play, but I don't know where the old developer put it on the computer or how to find it so that I can share it with the new developers that need it.
Does anyone know how I can find the file to share with the new developers and resolve the error above?
