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.
