我无法从 Google Plus 获取用户详细信息

I cannot get user details from Google Plus

Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) returns 行为空,即使我已经登录并且我的应用程序已经连接到该帐户。

这是我的代码:

@Override
public void onConnected(Bundle connectionHint) {
    mSignInClicked = false;
    Toast.makeText(this, "User is connected!", Toast.LENGTH_LONG).show();
    Plus.PeopleApi.loadVisible(mGoogleApiClient, null).setResultCallback(this);

    String personName = "No one!";
    if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
        Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
        personName = currentPerson.getDisplayName();
        String personGooglePlusProfile = currentPerson.getUrl();
        Toast.makeText(this, "Welcome " + personName, Toast.LENGTH_LONG).show();
    }


}

日志猫还显示: 请求可见圈子时出错:Status{statusCode=NETWORK_ERROR,resolution = null}

您需要在 Google 开发者控制台中启用 Google+ API。
