我想为我的应用程序使用Google登录名，但是我总是收到消息Status{statusCode=unknown status code: 12500, resolution=null，登录失败。有谁知道这是什么问题吗？

这是我的活动：

public class GruppenActivity extends AppCompatActivity implements
    GoogleApiClient.OnConnectionFailedListener,
    View.OnClickListener {

    private static final String TAG = "SignInActivity";
    private static final int RC_SIGN_IN = 9001;

    private GoogleApiClient mGoogleApiClient;
    private TextView mStatusTextView;
    private ProgressDialog mProgressDialog;

    private LernAppDB db;
    private SQLiteDatabase sqlDatabase;

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

        // Views
        mStatusTextView = (TextView) findViewById(R.id.status);

        // Button listeners
        findViewById(R.id.sign_in_button).setOnClickListener(this);
        findViewById(R.id.sign_out_button).setOnClickListener(this);
        findViewById(R.id.disconnect_button).setOnClickListener(this);

        db = new LernAppDB(this);
        sqlDatabase = db.getReadableDatabase();


        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestIdToken(getString(R.string.server_client_id)) …
