title: Stuck on project build with Google Maps v2 Android
body: <p>It was working fine. I still have the working map activity on my phone. I was working on trying to get Location tracking working and an error popped up in Android Studio. </p>
  
  <p>In the editor, I see a red error line on loading the xml layout saying it can't resolve the importer. When I build it fails saying it can't resolve GoogleMap. Any ideas?</p>
  
  <p>I've downloaded the latest Canary build and all SDK components are up to date.</p>
  
  <p>I'm targeting sdk 19 with a minimum sdk of 17. I have Java 1.7.0_45 installed.</p>
  
  <p>Here's the stacktrace for the compileDebug part of the process that chokes:</p>
  
  <pre><code>Exception is:
  </code></pre>
  
  <p>org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':Sitewalker:compileDebug'.
