title: Android - no known package when getting value for resource number
body: <p>I have recently updated my android sdk, and all of a sudden when i try and build my android app, the app appears on my device, but doesnt take the app icon and the name is the package name not the app name, and then crashes straight away.</p>
  
  <p>In the logcat, the image below is produced:</p>
