实际答案：

这对我有用，目前正在生产中，因此经过彻底测试

public class LoginActivity extends FragmentActivity实现了View.OnClickListener，GoogleApiClient.OnConnectionFailedListener {

private GoogleApiClient mGoogleApiClient;
    
private static final int RC_SIGN_IN = 9001;

private Button signUpGoogle;

@Override
    protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_login);

    signUpGoogle = (Button) findViewById(R.id.sign_up_google);
        signUpGoogle.setOnClickListener(this);

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                                .requestEmail()
                                .build();

      mGoogleApiClient = new GoogleApiClient.Builder(this)
                           .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                          .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                          .build();
}

@Override
    public void onClick(View v) {
        signInGoogle();
    }

private void signInGoogle() {
        Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

//     Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
        if (requestCode == RC_SIGN_IN) {
            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            handleSignInResultGoogle(result);
        }
    }

    private void handleSignInResultGoogle(GoogleSignInResult result) {
        AlertsAndLogs.log(TAG, "handleSignInResult:" + result.isSuccess());
        if (result.isSuccess()) {
            GoogleSignInAccount acct = result.getSignInAccount();
            if (acct != null) {
                //Get details from account: acc and do something when them
            }
        } else {
            AlertsAndLogs.toast("SignUp with Google failed " + result.toString());
        }
    }

@Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        AlertsAndLogs.logError(TAG, "onConnectionFailed:" + connectionResult);
    }

}

这是我在我的应用中使用Google plus登录的修改版本。适用于我支持的所有api版本（14及以上）。

简而言之，这个课程做了以下几点。

  • 在创建GoogleApiClient时设置Activity所需的范围。
  • 为登录按钮注册onClickListener。
  • 单击按钮时，会在Activtiy中开始签名并显示结果。
  • 在onActivityResult。
    • 处理登录结果

<强> SignInActivity.java 

    public class SignInActivity extends AppCompatActivity implements
            GoogleApiClient.ConnectionCallbacks,
            GoogleApiClient.OnConnectionFailedListener {

        private GoogleApiClient mGoogleApiClient;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_sign_in);
            initialize();
        }

        @Override
        public void onConnected(@Nullable Bundle bundle) {
            // Maybe only enable the sign in button as soon as the api is connected
        }

        @Override
        public void onConnectionSuspended(int i) {
            // Check best practices
        }

        @Override

                }
            });
        }

        private void setupGoogleApiClient() {

            GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestProfile()
                    .requestEmail()
                    .requestScopes(Drive.SCOPE_FILE, Drive.SCOPE_APPFOLDER)
                    .build();

            mGoogleApiClient.connect();
        }
    }

Google Plus登录即将被弃用，因此无需担心

  

从2019年3月7日开始，所有OAuth令牌请求的范围都以“加号”开头。 （即“ plus.me”，“ plus.login”，“ plus.profile.emails.read”等）会根据请求失败，并且可能最早在2019年2月15日开始间歇性地失败。
