title: Select multiple contacts from phone book in android
body: <p>I need to select contact numbers/emails from phone book in android.</p>
  
  <p>I have seen selecting one contact and getting the result back in <code>onActivityResult</code> from <a href="https://stackoverflow.com/questions/12123302/android-showing-phonebook-contacts-and-selecting-one">this link</a>.</p>
  
  <p>But I need multiple contacts to be selected from the phone book. How to achieve this?</p>
  
  <p>I don't want to make my custom list, is there a way to use androids built in functionality?</p>
