fragments.java

 @Override
    public void onBackPressed() {

        int count = fragmentManager.getBackStackEntryCount();
        //displays the fragments that are present on the activity with their names
        for (int i=count-1;i>=0;i--){
            String name = fragmentManager.getBackStackEntryAt(i).getName();
            Config.l("Count :"+i+" name :"+name);
