and my code to add and remove the fragment is as follows

        FragmentContainer fragContainer = container.get(container.size() - 1);
        Fragment fragment = fragContainer.getFragment();
        String tag = fragContainer.getTabName();
        FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction ft = manager.beginTransaction();

        mTabHost.setCurrentTabByTag(tag);

        if (!fragment.isAdded()) {

            ft.remove(fragment);
        }
        if(container.size()>0)
            container.remove(container.size() - 1);
        ft.replace(R.id.realtabcontent, fragment);
        ft.commitAllowingStateLoss();

Tried

• Updating support library

• Tried overriding onSaveInstanceState as

  @Override
  protected void onSaveInstanceState(Bundle outState) {
      // TODO Auto-generated method stub
      if (outState != null) {
          super.onSaveInstanceState(outState);
      }
  }
  

Answer 1

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState, this, TAG_TAFFER_TIME);
    mFragmentHolder = (RelativeLayout) findViewById(R.id.fragment);
    mFragmentTransaction = getSupportFragmentManager().beginTransaction();
    mFragmentTransaction.add(mFragmentHolder.getId(), mFragmentTafferTime, TAG);
    mFragmentTransaction.addToBackStack(TAG);
    mFragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    mFragmentTransaction.commit();
  } 

// On fragment change try to use this function
private void changeFragment(SherlockFragment fragment, String tag) {
    try {
        mFragmentTransaction.replace(mFragmentHolder.getId(), fragment, tag);
        mFragmentTransaction.addToBackStack(tag);
        mFragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
        mFragmentTransaction.commit();
    } catch (Exception exception) {

    }
}
