推荐答案

经过2天的研究，我发现，当时您注册您的Andr​​oid应用程序在谷歌云控制台 - >项目 - > API和权威性，它要求你指纹，以便产生的ClientID，不知怎么我的指纹是错误的（我不小心添加〜$ 此CMD前密钥工具-exportcert -alias androiddebugkey -keystore〜 /.android/debug.keystore | OpenSSL的SHA1 ），并且由于这一点，有人给了我错了指纹，是的根本原因：

After 2 days of research I found that at the time you register your android application in Google Cloud Console -> your project - > API and auth, it ask you for fingerprint in order to generate ClientID and somehow my fingerprint was wrong (I accidentally added ~$ before this cmd keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1) and due to this it was giving me wrong finger print and was the root cause of:

com.google.android.gms.auth.GoogleAuthException: getToken(Unknown Source) exception.
