[android] How to set a Fragment tag by code?

I know it's been 6 years ago but if anyone is facing the same problem do like I've done:

Create a custom Fragment Class with a tag field:

public class MyFragment extends Fragment {
 private String _myTag;
 public void setMyTag(String value)
 {
   if("".equals(value))
     return;
   _myTag = value;
 }
 //other code goes here
}

Before adding the fragment to the sectionPagerAdapter set the tag just like that:

 MyFragment mfrag= new MyFragment();
 mfrag.setMyTag("TAG_GOES_HERE");
 sectionPagerAdapter.AddFragment(mfrag);
