title: Query Contacts By Multiple LOOKUP_KEY
body: <p>The following code queries great for a single LOOKUP_KEY. </p>
  
  <pre><code>private final String lookup1 = "0r1-2E3C384E4846";
  private final String lookup2 = "0r2-442C4E523A2C3E2C443450";
  private final String lookup3 = "0r3-402C423442";
  
  /////////
  
  Uri lookUpUri = Contacts.getLookupUri(23, lookup1);
  Uri res = ContactsContract.Contacts.lookupContact(getContentResolver(), lookUpUri);
  Cursor contactCursor = getContentResolver().query(res, null, null, null, null);
  contactCursor.moveToFirst();
  Log.i("APP", "length: " + contactCursor.getString(contactCursor.getColumnIndex(Contacts.DISPLAY_NAME)) );
  </code></pre>
  
  <p>However, as the code might suggest I need to query for "x" number of contacts. Is there a way to query for all of these at once without having to loop over them? Looping will be horribly inefficient so I really want to avoid it.</p>
  
  <p>Thanks a ton gang!</p>
