refresh fragement after button press

Question

I have an android app that l am busy with but ran into a small problem. I am trying to refresh/restart my fragement after saving data by the use of the save button but l am getting the following err:

Attempt to invoke virtual method 'void android.support.v4.app.Fragment.setNextAnim(int)' on a null object reference

here is my code in the button:

    save1.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v) {
        //Util.displayMessage(getContext(),"Saving");
        String textToStore = contact1.getText().toString();
        String textToStore2 = contact2.getText().toString();
        String Url = "/gps/savetaxiroutes/"+imei+"/"+textToStore+"/"+textToStore2 +"/"+ sendNotification.toString()  ;

        AllContacts fragment = (AllContacts) 
                getFragmentManager().findFragmentById(R.id.thelayout2)

        getFragmentManager().beginTransaction()
                .detach(fragment)
                .attach(fragment)
                .commit();
        mPopupWindow.dismiss();
    }
    });

this is how the code is structured in my save button method.

Are you trying to refresh the fragment UI after saving data? — Sarath Kn, Jun 15 '18 at 09:35
the error clearly saying you are calling setNextAnim(int) with null object — Mohit Madaan, Jun 15 '18 at 09:37
@Sarath yes l am trying to refresh the fragement UI after saving data — Evans Munatsa, Jun 15 '18 at 09:42
Try to update the UI manually or use data binding, instead of detaching and attaching the fragment for the purpose of UI update. — Sarath Kn, Jun 15 '18 at 09:45
@Sarath, it not work as l though it would but l got a solution from another post here on stack overflow after over an hour of research: https://stackoverflow.com/questions/32295798/how-do-i-redirect-a-fragment-to-new-fragment — Evans Munatsa, Jun 15 '18 at 10:36
