Facebook Android SDK, UiLifecycleHelper StackOverflow error

Question

Uzyskanie dziwnego błędu StackOverflow z UiLifecycleHelper. Wygląda na to, że próbuje załadować obiekt serializowany, ale obiekt ObjectInputStream uruchamia się w pętli rekursywnej, prawdopodobnie z powodu uszkodzonych danych. Dzieje się tak tylko w metodzie onCreate. Oto ślad stosu

Aktualizacja

StackOverflowError faktycznie występuje również w stanie onSaveInstance, ale pętle pisze ObjectStream. Mamy tylko 4 dzienniki awarii pokazujące to, z 49 dziennikami awarii na odczyt w onCreate. Oto kod, który jest używany:

UiHelper jest wywoływany we wszystkich oczekiwanych metodach, onCreate, onResume, onPause, onSaveInstanceState, onDestroy bez zbaczania z dokumentów. Cały inny kod Facebooka jest pokazany poniżej.

//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)) {

Answer 1

Parametry i zmienne lokalne są alokowane na stosie (z typów referencyjnych obiektu mieszka na stercie i zmiennej odniesienia że Object). Stos zwykle znajduje się na górnym końcu przestrzeni adresowej użytkownika, a ponieważ jest zużyty, kieruje się w stronę dolnej przestrzeni adresowej adresu IP (czyli w kierunku zera).

gui programowanie możliwe jest generowanie pośredniej rekursji. Dla przykładu, Twoja aplikacja może obsługiwać komunikaty o malowaniu i podczas przetwarzania może wywoływać funkcję powodującą wysłanie przez system kolejnej wiadomości malowania . Tutaj nie nazywasz się jawnie, ale system OS/VM zrobił to za Ciebie.

jakie napotkał ten sam błąd before.Do jedno tylko usunąć inicjalizacji bezpośrednio poniżej klasy i przenieść go wewnątrz onCreate() lub onResume().
