Facebook Android SDK, UiLifecycleHelper StackOverflow error

Question

Ottenere uno strano errore StackOverflow da UiLifecycleHelper. Sembra che stia cercando di caricare un oggetto serializzato, ma l'ObjectInputStream viene eseguito in un ciclo ricorsivo, probabilmente a causa di dati corrotti. Succede solo nel metodo onCreate. Ecco la traccia dello stack

Aggiornamento

Lo StackOverflowError in realtà si verifica anche in stato di onSaveInstance, ma loop in ObjectStream scrive. Abbiamo solo 4 registri di crash che mostrano questo, con 49 registri di crash sul read in onCreate. Ecco il codice che viene utilizzato:

L'uiHelper è chiamato in tutti i suoi metodi previsti, onCreate, onResume, onPause, onSaveInstanceState, onDestroy senza nessuna deviazione dai documenti. Di seguito è riportato l'altro codice Facebook utilizzato.

//onClick facebook button 
private void facebook() { 
    Session session = Session.getActiveSession(); 
    if (session != null && session.isOpened()) { 
     Log.v("W", "Already have session"); 
     publishog(session); 
    } else { 

     Session.openActiveSession(WWhisperActivity.this, true, callback); 
    } 
} 

private void onSessionStateChange(Session session, SessionState state, 
     Exception e) { 
    if (e != null && !e.getLocalizedMessage().contains("user denied")) { 
     BugSenseHandler.sendException(e); 
    } 
    if (state.equals(SessionState.OPENING)) { 
     Log.v("W", "Session opening state"); 
    } else if (state.equals(SessionState.CREATED) 
      || state.equals(SessionState.CREATED_TOKEN_LOADED)) { 
     Log.v("W", "Session created state"); 
    } 
    if (state.isOpened()) { 
     Log.v("W", "Open session"); 
     if (!session.getPermissions().contains("publish_actions")) { 
      Log.v("W", "Getting publish permission"); 
      Session.NewPermissionsRequest r = new Session.NewPermissionsRequest(
        this, Arrays.asList("publish_actions")); 
      session.requestNewPublishPermissions(r); 
     } else { 
      Log.v("W", "Session opened, publishing og"); 
      publishog(session); 
     } 
    } else if (state.equals(SessionState.CLOSED) 
      || state.equals(SessionState.CLOSED_LOGIN_FAILED)) { 
     Log.v("W", "Session not open"); 
     session.closeAndClearTokenInformation(); 
     if (state.equals(SessionState.CLOSED_LOGIN_FAILED)) { 
      if (e == null || !e.getLocalizedMessage().contains("abort") 
        && !e.getLocalizedMessage().contains("user denied")) 
       Session.openActiveSession(this, true, callback); 
     } 
    } 
} 

private void publishog(Session session) { 
    Log.v("W", "Publishing OG"); 
    WObject wo = GraphObject.Factory.create(WObject.class); 
    wo.setId(w.wid); 
    wo.setUrl(shorturl);

    com.facebook.Request.executePostRequestAsync(session, 
      "me/whisper_app:share", ws, 
      new com.facebook.Request.Callback() { 

       @Override 
       public void onCompleted(Response response) { 
        pd.dismiss(); 
        if (response.getError() != null) { 

        } else { 

        } 

       } 

      });

Answer 1

parametri e le variabili locali sono assegnati sullo stack (con tipi di riferimento l'oggetto vive sul mucchio e una variabile fa riferimento che oggetto). Lo stack in genere si trova all'estremità superiore dello spazio di indirizzamento dello e, man mano che viene utilizzato, si dirige verso il fondo dello spazio di indirizzamento (ovvero verso lo zero).

programmazione gui è possibile generare ricorsione indiretta. Per l'esempio , la tua app potrebbe gestire i messaggi di disegno e durante l'elaborazione di potrebbe chiamare una funzione che fa sì che il sistema invii un altro messaggio di vernice . Qui non ti sei chiamato esplicitamente, ma l'OS/VM lo ha fatto per te.

ho incontrato lo stesso errore before.Do una cosa è sufficiente rimuovere qualsiasi inizializzazione direttamente sotto la classe e spostarlo all'interno onCreate() o onResume().
