Question

我无法将我的应用与Google登录集成。似乎从 handleSignInResult（GoogleSignInResult结果）返回的结果是错误的（应该是真的）。

有人可以帮助解释为什么会这样吗？我无法弄清楚会发生什么事情会导致它失败（包含和不包含令牌都会失败）。

public class GoogleSignIn extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener{

//Pass this client ID to the requestIdToken or requestServerAuthCode method when you create the GoogleSignInOptions object.

private final int RC_SIGN_IN = 9001;
private final String TOKEN_CRED_ID = "*******-the web application credentials copied from https://console.developers.google.com/apis/credentials";
private GoogleApiClient mGoogleApiClient;
private SignInButton SignInBtn;
private TextView SignInStatusView;



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

    SignInBtn = (SignInButton) findViewById(R.id.sign_in_button);
    SetButtons();
    SignInStatusView = (TextView) findViewById(R.id.google_sign_in_status);
    // Get the user's ID and basic profile info using google

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


    // This object is used in order to access the Google API for Signing in

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


    SignInBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signIn();
        }
    });

    final Button SignOutBtn = (Button) findViewById(R.id.sign_out_and_disconnect);
    SignOutBtn.setVisibility(View.GONE);
    SignOutBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signOut();
        }
    });


}

        @Override

            GoogleSignIn.this.finish();
        }
    });


}

    super.onStart();
    mGoogleApiClient.connect();
}

    super.onStop();
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }

}

@Override

    // Connection failed completely. Sign in and other functions are not available.
    System.out.println("ERROR ::: Problems with connection");
}

1。获取SHA1密钥Link

2。粘贴PAckage名称和SHA-1指纹，然后点击启用Google登录。然后最后点击生成配置文件以下载您的google-services.json From This Link

3. 将google-services.json文件移至应用文件夹Reffer Link
