Accessing contact list

Accessing contact list

1. need to declare constants like projection,selection etc

   • but android has its own ready made class for constants required for contact called "ContactContract"
     • Create RecyclerView, ListView
       • initialize by passing Simple curserAdapter without passing curser to it as we getting it from loader Manager
         • write code in Loader manger CallBacks
           • use swapCurser method to add new cursor with data in Simple cursor adapter
             • use CursorLoader class
           • implement LoaderManager.Callbacks
         • use simpleCursorAdapter class
         • Create Constants for column names, view id etc so adapter can map view with data
     • import ContactContract
