(Android) Google Play Console... issue with new app release

Questions
1

Hello,
I’m trying to move from PhoneGap Build but when I upload a new version on Google Play Console I receive this error:

Loading failed
You have uploaded an APK that is signed with a different certificate from your previous APKs. You must use the same certificate. Existing APKs are signed through certificates with these fingerprints:
[ SHA1: ...]
. The certificates used to sign the APK you uploaded have these fingerprints:
[ SHA1: ... ]

How can I fix it?
Thanks.

The message means that the new version you are uploading was signed with a different keystore file than the last one you uploaded.

If you google "You have uploaded an APK that is signed with a different certificate", you’ll find a few ways to work around this.

Ok, I’ve fixed (it was a problem with the androidAlias name).
