我在我的应用程序中尝试使用 google plus 添加注册时遇到问题，但出现此错误：

这是我拥有的代码：

private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
private ProgressDialog mConnectionProgressDialog;
private PlusClient mPlusClient;
private ConnectionResult mConnectionResult;
private SignInButton signupButtonPlus;

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.signup);
            mPlusClient = new PlusClient.Builder(this, this, this)
                    .setVisibleActivities("http://schemas.google.com/AddActivity",
                            "http://schemas.google.com/BuyActivity")
                    .setScopes("PLUS_LOGIN") // Space separated list of scopes
                    .build();
            initWidgets();

        }

在initwidgets()我有：

mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");
        signupButtonPlus = (SignInButton) findViewById(R.id.sign_in_button_plus);
        signupButtonPlus.setOnClickListener(this);

其余的 google plus 的东西：

@Override
    public void onClick(View v) {
        if (v.getId() == R.id.sign_in_button_plus) {
            Log.v("--", "gplus");
            if (!mPlusClient.isConnected()) {
                mPlusClient.connect();
            }
        }
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode,
            android.content.Intent data) {
        Log.v("--", resultCode+" fb");
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && resultCode == RESULT_OK) {
            mConnectionResult = null;
            mPlusClient.connect();
        } else
            fbLoginManager.loginSuccess(data);
    }



    @Override
    public void onDisconnected() {
        Log.e("gPlus", "disconnected");
    }

    @Override
    public void onConnected(Bundle b) {
        String accountName = mPlusClient.getAccountName();
        Toast.makeText(this, accountName + " is connected.", Toast.LENGTH_LONG)
                .show();
    }
