Show DialogFragment from onActivityResult

Question

I have the following code in my onActivityResult for a fragment of mine:

onActivityResult(int requestCode, int resultCode, Intent data){    //other code    ProgressFragment progFragment = new ProgressFragment();      progFragment.show(getActivity().getSupportFragmentManager(), PROG_DIALOG_TAG);    // other code } 

However, I'm getting the following error:

Caused by: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState    

Anybody know what's going on, or how I can fix this? I should note I'm using the Android Support Package.

If you use Android support library, onResume method isn't the right place, where to play with fragments. You should do it in onResumeFragments method, see onResume method description: http://developer.android.com/reference/android/support/v4/app/FragmentActivity.html#onResume%28%29

So the correct code from my point of view should be:

private boolean mShowDialog = false;  @Override protected void onActivityResult(int requestCode, int resultCode, Intent data){   super.onActivityResult(requestCode, resultCode, data);    // remember that dialog should be shown   mShowDialog = true; }  @Override protected void onResumeFragments() {   super.onResumeFragments();    // play with fragments here   if (mShowDialog) {     mShowDialog = false;      // Show only if is necessary, otherwise FragmentManager will take care     if (getSupportFragmentManager().findFragmentByTag(PROG_DIALOG_TAG) == null) {       new ProgressFragment().show(getSupportFragmentManager(), PROG_DIALOG_TAG);     }   } }
