Hey YuviDroid Thanks for reply,
Actually I am not calling new activity. In my activity's onCreate ()
method I am showing the list. In the same activity I am deleting list
record But because display logic of list is in the onCreate() method
of same activity therefore If I call startActivity(getIntent()); then
list updates instantly. and If don't call startActivity(getIntent());
then record is deleted but list is not updates instantly.
Now I want update list instantly.
