title: Android HelloGoogleMaps tutorial exception
body: <p>I'm working with the HelloGoogleMaps tutorial on the Android Developers' Resource page (<a href="http://developer.android.com/resources/tutorials/views/hello-mapview.html" rel="nofollow">http://developer.android.com/resources/tutorials/views/hello-mapview.html</a>) and when I run part 1 of the application ("Creating a Map Activity") on my emulator, I get the message "The application HelloGoogleMaps (process com.example) has stopped unexpectedly. Please try again." I'm pretty sure that I followed all of the instructions correctly, however I'm not sure that I set up my emulator environment correctly. Can anyone please help me figure out what's going on? Thanks.</p>
  
  <p>Here's the output from logcat:  </p>
