saving fragment transaction whereever

Question

initially I have an activity A in which I'm gonna open one fragment so here how can i save that fragment So, that when I launch my application after destroying it restores that fragment in that same Activity in same position

For, answering convenience here's my fragment transaction code:

    Fragment newFragment = new ece_frag();
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.setCustomAnimations(R.anim.fade_in,R.anim.fade_out);
    transaction.replace(R.id.frame_layout, newFragment);
    transaction.commit();

Lets say you have 3 fragments A,B and C.

I give index to each fragment like this say 0->A, 1->B, 2->C. So when i do this, I also save the index like the code below:

Fragment newFragment = new A();
FragmentTransaction transaction = 
getFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.anim.fade_in,R.anim.fade_out);
transaction.replace(R.id.frame_layout, newFragment);
transaction.commit();
SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt("last_fragment", 0);//For fragment A saving index 0
editor.commit();

And then in onCreate you can use an if case like this:

SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
//0 here is the default value
int lastFragment = sharedPref.getInt("last_fragment", 0);

Then you can do this

switch(lastFragment){
  case 0:
  //Load your fragment Here according to the index.
  break;
  case 1:
  //Load your fragment Here according to the index.
  break;
  case 2:
  //Load your fragment Here according to the index.
  break;

}

Hope this helps.
