Wyjątek jako Stan nieudanego zapisu: aktywny Fragment wyczyścił indeks: -1 po naciśnięciu przycisku home urządzenia z Androidem

Question

Mam do czynienia z jakimś dziwnym problemem, gdy naciskam przycisk home Androida i podczas uruchamiania nowej aktywności.

Moja StackTrace jest następujący

i mój kod, aby dodać i usunąć fragment brzmi następująco

 FragmentContainer fragContainer = container.get(container.size() - 1); 
     Fragment fragment = fragContainer.getFragment(); 
     String tag = fragContainer.getTabName(); 
     FragmentManager manager = getSupportFragmentManager(); 
     FragmentTransaction ft = manager.beginTransaction(); 

     mTabHost.setCurrentTabByTag(tag); 

     if (!fragment.isAdded()) { 

      ft.remove(fragment); 
     } 
     if(container.size()>0) 
      container.remove(container.size() - 1); 
     ft.replace(R.id.realtabcontent, fragment); 
     ft.commitAllowingStateLoss(); 

Tried

• Aktualizowanie biblioteki support

• Wypróbowywany przesłanianie onSaveInstanceState jak

  @Override 
  protected void onSaveInstanceState(Bundle outState) { 
      // TODO Auto-generated method stub 
      if (outState != null) { 
       super.onSaveInstanceState(outState); 
      } 
  } 
  

Answer 1

@Override 
    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState, this, TAG_TAFFER_TIME); 
    mFragmentHolder = (RelativeLayout) findViewById(R.id.fragment); 
    mFragmentTransaction = getSupportFragmentManager().beginTransaction(); 
    mFragmentTransaction.add(mFragmentHolder.getId(), mFragmentTafferTime, TAG); 
    mFragmentTransaction.addToBackStack(TAG); 
    mFragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); 
    mFragmentTransaction.commit(); 
    } 

// On fragment change try to use this function 
private void changeFragment(SherlockFragment fragment, String tag) { 
    try { 
     mFragmentTransaction.replace(mFragmentHolder.getId(), fragment, tag); 
     mFragmentTransaction.addToBackStack(tag); 
     mFragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); 
     mFragmentTransaction.commit(); 
    } catch (Exception exception) { 

    } 
}
