How to generate a new KEYSTORE file for Unity based on App Signing Certificate?
I have enabled "Google Play App Signing" for the app that already existed on Google play.
Now I cannot upload new app versions with the old KEYSTORE (.keystore) file.
Should I generate a new KEYSTORE file based on certificate fingerprints (attached in the image bellow) and how?
NOTE: This question is specific for the Unity platform. (2018 Release of Unity)
The actual error message I get after the new app version upload is like this:
Upload failed
You uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has fingerprint:
[ SHA1: 9A:... ]
and the certificate used to sign the APK you uploaded have fingerprint:
[ SHA1: 36:... ]
When you enrolled in App Signing by Play, it looks like you have opted to create an upload key (probably by creating a new keystore). From now on, you should sign the APKs you upload to the Play Console with this new key/keystore. Note that should still be able to upload APKs with the old keystore. I can't see the full certificate fingerprints on your screenshots, but it seems from the error message that you're uploading an APK that is signed with neither the upload key nor the deployment (a.k.a app signing) key. Try to locate the keystores and identify the aliases you've used when creating the upload key and use those.
