this is what worked for me as seen here   Just use it or add it to a static class helper and just call it from anywher in your project       Current Activity instance will go through its lifecycle to onDestroy   and a new instance then created after it      SuppressLint  NewApi     public static final void recreateActivityCompat final Activity a        if  Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB          a recreate          else         final Intent intent   a getIntent          intent addFlags Intent FLAG ACTIVITY NO ANIMATION         a finish          a overridePendingTransition 0  0         a startActivity intent         a overridePendingTransition 0  0

I think that the best choice for you is using SwipeRefreshLayout View in your layout  Then set RefreshListener like   mySwipeRefreshLayout setOnRefreshListener              new SwipeRefreshLayout OnRefreshListener                      Override                 public void onRefresh                         Log i  Fav     onRefresh called from SwipeRefreshLayout                            This method performs the actual data-refresh operation                         The method calls setRefreshing false  when it s finished                      request        call what you want to update in this method                     mySwipeRefreshLayout setRefreshing false                                            For more details click this link
