谷歌标志不适用于低于 Nougat 的 API

Question

我尝试按照 Google 登录上的 sn-ps 进行操作，但我没有将其放在活动上，而是在片段上使用它。它只适用于牛轧糖。问题似乎取决于给予谷歌的意图。每当我点击 Google 登录时，它都会关闭我的应用。

对话框显示在我的应用程序之外，并且不会返回到我的片段。它只是关闭。

这是我的代码：它与 sn-p 几乎相同。但这里的问题是，当我点击登录 Google 时应用程序关闭时，它让用户每次都选择电子邮件，但它不会返回到 onActivityResult，因为我的 logcat 上没有记录数据

public class LoginFragment extends Fragment implements OnConnectionFailedListener {
    private FragmentManager fragmentManager;
    private FragmentTransaction fragmentTransaction;
    private Button signUp, login;
    private View view;

    private SignInButton signInButton;

Answer 1

问题已通过删除 清单中的 android:noHistory="true"。这是以前防止用户返回登录活动的解决方案。

Answer 2

你必须使用你实际的安卓手机而不是模拟器，因为它有一个旧版本的谷歌播放
