title: Android - Unable to destroy activity after finish, caused by IllegalStateException: Can not perform this action after onSaveInstanceState
body: <p>I have an activity in my app with 3 fragments. When a button is pushed on the first one, a method is called in the Activity that does some irrelevant stuff and then calls <code>finish()</code>.</p>
  
  <p>This triggers <code>onPause()</code> on the fragment, which does more irrelevant stuff and then calls <code>super.onPause()</code>.</p>
  
  <p>The app then loads the old Activity it came on (logically following the view stack), and suddenly crashes with the following exception when <code>onDestroyView()</code> is called on the Fragment:</p>

  <p>The error appears to happen when trying to remove a <code>MapFragment</code> from the main Fragment. I know that you're not supposed to have fragments within fragments, but the code worked in the past and there's no way around it anyway.</p>
  
  <pre><code>@Override
  public void onDestroyView() {
      SupportMapFragment f = (SupportMapFragment) activity.getSupportFragmentManager().findFragmentById(R.id.fragment_map);
      if (f != null) {
          activity.getSupportFragmentManager().beginTransaction().remove(f).commit();
      }
      super.onDestroyView();
  }
  </code></pre>
  
  <p>I looked around for a fix here on SO already (most notably <a href="https://stackoverflow.com/questions/7469082/getting-exception-illegalstateexception-can-not-perform-this-action-after-onsa">getting exception &quot;IllegalStateException: Can not perform this action after onSaveInstanceState&quot;</a>), but none of them were applicable to my current problem.</p>
