Android - AuthUI - Feuerbasis funktioniert nicht, wenn sie von Facebook-Login

Question

Willkommen allerseits, A habe eine Anwendung in Android-Studio, Ich benutze die Feuerbasis, aber wenn der Benutzer Login von AuthUI einzuloggen von (Facebook oder Google)

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(); 
    } 

und der Benutzer Erfolg Login dann die Feuerbasis funktioniert nicht. Wenn ein Benutzer ausloggen

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

die Feuerbasis anfangen zu arbeiten normalerweise

Ich benutze dies für meine Google-Zeichen ein und aus. funktioniert super! Sie werden sich natürlich an Ihre Ressourcen anpassen müssen. Wenn das Problem dadurch nicht behoben wird, liegt möglicherweise ein Problem mit der Bibliotheksabhängigkeit vor. lassen Sie mich
