How to call Android contacts list?

Question

I\'m making an Android app, and need to call the phone\'s contact list. I need to call the contacts list function, pick a contact, then return to my app with the contact\'s

Answer 1

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{
  if (requestCode == PICK_CONTACT && intent != null) //here check whether intent is null R not
  {  
  }
}

because without selecting any contact it will give an exception. so better to check this condition.
