title: Android: Fragments backStack
body: <p>Im trying to load an new fragment when a method is called. This method creates a new fragment and "replaces" the other fragment:</p>
  
  <pre><code>private void showTestFragment(Fragment oldFragment, boolean addBackStack, BaseAdapter adapter, int position) {
      Cursor cursor = (Cursor)adapter.getItem(position);
      if(cursor != null){
  
          int idx = cursor.getColumnIndexOrThrow(Episode._ID);
          long rowId = cursor.getLong(idx);
  
          FragmentManager fragmentManager = getFragmentManager();
          FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
  
          if(oldFragment != null){
              Log.i(TAG, "Removing the old fragment");
              fragmentTransaction.remove(oldFragment);
          }
  
          TestFragment testFragment =  new TestFragment();
          testFragment.setId(rowId);
  
          fragmentTransaction.add(android.R.id.content, testFragment);
  
          if(addBackStack){
              Log.i(TAG, "Added to the backstack");
              fragmentTransaction.addToBackStack(TAG);
          }
  
          fragmentTransaction.commit();
          Fragment f = getFragmentManager()
                  .findFragmentById(R.id.index);
          Log.i(TAG, "after commit, frag is "+ f);
      }
  }
  </code></pre>
  
  <p>This works fine, until i go back. The last fragment, should be removed when i go back. Before i'm going to implement methods on the activities</p>
  
  <pre><code>public void onBackPressed(){}
  </code></pre>
  
  <p>to remove the last fragment, i want to know if i handle the fragment change correctly. It looks like i'm missing something here..</p>
