title: Android Collaborate Git with google play services maps
body: <p>I have a problem.
  We are a students group, who are developing a Android Project. We use Eclipse and git (bitbucket) to share project in three different computers.
  Our project uses google maps, and we had to get a key to use google maps.
  We don't know how we can share this project by git (between ourselves). Do we need new key?</p>
  
  <p>Does anyone have an example of this problem? 
  Does anyone know a guide?</p>
  
  <p>Thanks.</p>
