Android :: Picking A Contact And Returning To The Parent Activity

I wish to re-use the Contacts application in a way to enable the user to pick a contact and return it to the parent activity (my application's activity).

For achieving this, I want to inquire about the kind of Intent that will be needed to launch the contacts application.

Intent i = new Intent(Intent.ACTION_GET_CONTENT, ?); startActivityForResult(.....);

What should be the second argument here ?

In the deprecated Contacts API, I could use the following snippet, but not sure about ContactsContract:

Intent i= new Intent(Intent.ACTION_GET_CONTENT,People.CONTENT_URI); startActivityForResult(i, reqCode);
