Android Google+ sign-in issue

Question

I have a android application that with Google+ sign-in function. I have enabled Google+ API and create oauth 2.0 user client id for my application. Also, I download the JSON file from https://developers.google.com/mobile/add? platform=android. I generate the signed apk(release) and the google+ sign-in function works. My problem is that if I upload the signed apk to google play as a beta version. The Google+ sign-in function will be failed!!! The error sign-in result: Status

{statusCode=DEVELOPER_ERROR, resolution=null}.

I have no idea about this condition, please have advised to me. Many thanks.

Answer 1

Generate and add your SHA1 key to the Google Project Console. This will solve your issue.

keytool -list -v -keystore KEYSTORE_PATH -alias ALIAS_NAME

Use your Release keystore.

Answer 2

You have to enter SHA 1 certificate fingerprints from Google Play Console to your Google Project Console. Generated release SHA1 fingerprints works for signed apk but doesn't work for live apps anymore.

Answer 3

You need to add your SHA1 key to firebase console configuration. You can do it in this way:

Firebase console ( https://console.firebase.google.com ) -> your project -> configuration -> scroll to

You can find your SHA1 key running "Signin report" from Android Studio:

Then, look the "run tab" and click the button:

I think it's the easier way. Hope this help.
