Question

Answer 1

Your code for adding fragment to backstack should be like:

getFragmentManager() .beginTransaction() .replace(R.id.content_frame, Entry_Account.newInstance(), Entry_Account.TAG).addToBackStack("Some string") .commit();

Then On Activity's onBackPressed method,use this snippet:

@Override
public void onBackPressed () {
if(getFramentManager().getBackStackEntryCount()>0){
      // popback statck.
}
 else{
     // finish your activity.
 }
}
