IllegalStateException while showing DialogFragment after back from AppCompatActivity

Question

I am starting a FragmentActivity from a custom DialogFragment and after I come back the original Activity and try to open the dialog again I get:

IllegalStateException: Can not perform this action after onSaveInstanceState

I don't understand why is it happening, if I dismiss the dialog from the original activity than I can show it again as many times as I want, but if I start a new Activity from the DialogFragment after that I cannot show any dialog again because I get the exception.

Here is my code, this method is in my DialogFragment:

 public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3){
     mSearchLocationType = position;
     switch(position){
         case PSL_CURRENT_POSITION: // I can show the dialog again after this.
             break;
         case PSL_MAP_POINT:
             Intent selectMapPoint = new Intent(parentActivity, SelectMapPointActivity.class);     
             selectMapPoint.putExtra(SelectMapPointFragment.EXTRA_SELECTED_POS, mSearchLocation);
             parentActivity.startActivityForResult(selectMapPoint, REQ_MAP_POINT); 
             // After returning this Activity and trying to show ANY DialogFragment the app crashes.
             break;
         case PSL_ADDRESS:
             Intent selectAddress = new Intent(parentActivity, SelectAddressActivity.class);
             parentActivity.startActivity(selectAddress); // Also from this Activity, makes no difference.
             break;
      }
      dismiss();
 }    

I am showing the dialog like:

if(!selectPoiAroundDialog.isVisible())
    selectPoiAroundDialog.show(parentActivity.getSupportFragmentManager(), "mSelectPoiCategoryDialog");

What I have tried already:

• Override the show() method of the DialogFragment and use this code to show the dialog:

  FragmentTransaction ft = manager.beginTransaction();
  ft.add(this, tag);
  ft.commitAllowingStateLoss();

• Debug the app and check if all the lifecycle methods are called, but it seems normal to me, each of the times the onDestroyView() method of the DialogFragment is called.

• Override the show() and onDismiss() method of the DialogFragment and track if it is shown or not.

This is a corporate app and has a bad design, so the class which I am trying to modify (where I am showing the dialog) is not child of Activity or Fragment. ´parentActivity´ is accessed by a static method of the application class, but I am sure that it has the right Activity. Do you think this can cause the problem?

EDIT: The full stacktrace is when I useing commitAllowStateLoss():

• I also tried to override the onSaveInstanceState() method, it didn't helped.

If I override the show() method and try to commit the fragment with commitAllowingStateLoss() than I get the first exception.

Answer 1

I figured out the problem. When the app quit from an Activity it didn't remove the reference of it from parentActivity, so when I tried to show the dialog again I gave a reference of the destroyed activity.

Thanks for your time!
