Question

我的主要活动扩展了BaseGameActivity，我试图获取排行榜中显示的用户名。我尝试使用：

Plus.AccountApi.getAccountName(getApiClient());

但它没有用，我得到了：

我知道有一种方法可以使用GoogleApiClient.Builder，但我正在寻找另一种方式我使用BaseGameActivity。

Answer 1

在onCreate方法中添加 setRequestedClients（BaseGameActivity.CLIENT_GAMES | BaseGameActivity.CLIENT_PLUS）;

在super.conCreate（savedInstanceState）之前

@Override
public void onCreate(Bundle savedInstanceState) {
    // set requested clients (games and cloud save)
    setRequestedClients(BaseGameActivity.CLIENT_GAMES |
            BaseGameActivity.CLIENT_PLUS);

    super.onCreate(savedInstanceState);


    setContentView(R.layout.activity_leaderboard);
}
