title: Save the state of navigation drawer fragments
body: <p>I am trying to save the state on the navigation drawer fragments as I toggle between different fragments within the navigation drawer. For Example: I start at Fragment A fire some events, then toggle to Fragment B. Then I want to see the same state of Fragment A when I toggle back to Fragment A from Fragment B. </p>
  
  <p>I tried using the onSavedInstanceState(Bundle savedInstanceState) but it only gets called when the orientation changes in the fragment life cycle. A new fragment gets created whenever I toggle to a new fragment and I can't figure out how to save data from a fragment and reload it on another visit.</p>
  
  <p>I don't want to use backstack() either because it removes all the fragments up to the fragment that I want to restore. </p>
  
  <p>Below is how I call the fragments on the drawer toggle.</p>
  
  <pre><code>private void selectItem(int position) {
  
      Fragment fragment;
      String TAG;
  
      switch (position) {
      case 0:
          fragment = new FragmntA();
          TAG = "A";
          break;
      case 1:
          fragment = new FragmentB();
          TAG = "B";
          break;
      case 2:
          fragment = new FragmentC();
          TAG = "C";
          break;
      case 3:
          fragment = new FragmentD();
          TAG = "D";
          break;
      case 4:
          fragment = new FragmentE();
          TAG = "E";
          break;
      default:
          fragment = new FragmentA();
          TAG = "A";
      }
  
      FragmentManager fragmentManager = getSupportFragmentManager();
      FragmentTransaction ft = fragmentManager.beginTransaction();
      ft.replace(R.id.content_frame, fragment, TAG);
      ft.commit()
  </code></pre>
  
  <p>I don't know if there is any point in the fragment life cycle where I can save its state. Any help would be appreciated. Thanks.</p>
