android - 使用 TabLayout Viewpager 时出现 "Already managing a GoogleApiClient with id 0"异常

Question

我想使用 TabLayout ViewPager Fragments 集成 Google Signup。 ViewPager 包含两个 fragment LoginFragment 和 RegistrationFragment，并且都包含“Google 注册”按钮。

问题是我在启动 Activity 时遇到以下错误。

java.lang.IllegalStateException: Already managing a GoogleApiClient with id 0

我正在尝试下面的代码

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

 // Configure sign-in to request the user's ID, email address, and basic
 // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
        gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail()
                .build();

        buildGoogleApiClient();

     // .....
 }

private synchronized void buildGoogleApiClient() {
    /** build_client */
   try {
       mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
               .enableAutoManage(getActivity() /* FragmentActivity */, this /* OnConnectionFailedListener */)
               .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
               .build();
   } catch (Exception e) {
       e.printStackTrace();
   }
}

和

@Override
public void onStart() {
    super.onStart();
    if (mGoogleApiClient != null) {
        mGoogleApiClient.connect();
    } 

}

@Override
public void onStop() {
    Log.d("GARG", "***** on Stop ***** ");
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        Log.d("GARG", "***** on Stop mGoogleApiClient disconnect ***** ");

        mGoogleApiClient.stopAutoManage(getActivity());
        mGoogleApiClient.disconnect();
    }
    super.onStop();
}

还有其他连接 Google API 客户端的方法吗？ 知道我哪里做错了以及正确的方法吗？

我认为您正在尝试通过已经构建和连接的 googleApiClient 进行构建和连接。这可能会解决您的问题:

if(mGoogleApiClient == null || !mGoogleApiClient.isConnected()){
 try {
   mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
           .enableAutoManage(getActivity() /* FragmentActivity */, this /* OnConnectionFailedListener */)
           .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
           .build();
 } catch (Exception e) {
   e.printStackTrace();
 }
}
