title: Google Maps Android
body: <p>I recently completed an android project for google maps. It's an app that performs distance calculation named Android Taxi Meter. </p>
  
  <p>I followed all the rules to get api v2 for maps and did all jobs perfectly. Now the problem is that I have some starting screens splash, login, language, info, and finally in last map activity which is actually calculating the distance between two places entered by customer. When I run this project as a whole it does not show map on it. </p>
  
  <p>But when I just separated the map activity as a separate project it works. I'm now confused, what is the matter? A separate map activity is working properly but with other starting activities it doesn't show the map, while the rest of project works normally.</p>
