title: How to add external google_play_service library in my project? (other than own sdk's)
body: <p>I have an android project from bitbucket with its own google play
  service library. When i add that library to my project <code>eclipse</code> is
  giving me an error on <code>@integer/google_play_service_version</code>. But
  if i am adding my own sdk's lib into the project i am not able to see
  the correct output (eg. unable to load maps, etc).</p>
  
  <p>So can anyone please help me?? Thank you in advance.</p>
