title: Adding entire phone's contact list into application database
body: <p>I'm new to Android and developing an app in which I need to store entire phone's contact list into my application database on the launch of the application.</p>
  
  <p>As I searched on web, all I got the answers for inserting contacts one by one in your application database. But I want to have the entire contact list into my database and then work on that contact database.</p>
  
  <p>Any help will be appreciated. Thanks :)</p>
