アンドロイド - AuthUI - Facebookの

Question

によってログインが皆、 Aを歓迎するときfirebaseは動作しませんが、私はfirebaseを使用 、アンドロイドスタジオでアプリケーションを持っていますが、とき（Facebookやグーグル）でログインするAuthUIにより、ユーザのログイン

try { 
     startActivityForResult(
       AuthUI.getInstance() 
         .createSignInIntentBuilder() 
         .setAvailableProviders(
           Arrays.asList(new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(), 
             new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build(), 
             new AuthUI.IdpConfig.Builder(AuthUI.FACEBOOK_PROVIDER).build() 
           )) 
         .build(), 
       RC_SIGN_IN); 
    } catch (Exception e) { 
     Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show(); 
    } 

とユーザの成功のログインはその後 firebaseは動作しません。 ユーザーのログアウト、

AuthUI.getInstance() 
      .signOut(this) 
      .addOnCompleteListener(new OnCompleteListener<Void>() { 
       public void onComplete(@NonNull Task<Void> task) { 
        // user is now signed out 
        // finish(); 
       } 
      }); 

がfirebaseは、私は私のGoogleのサインインとアウトのためにこれを使用し、通常

を作業を開始。よく働く！もちろん、あなたのリソースに適応する必要があります。これで問題が解決しない場合は、ライブラリの依存関係に問題がある可能性があります。私は
