  <p>However the application is able to connect to Play services, and get a registration id. Also sending messages seems to work fine - at least no errors are logged.</p>
  
  <p>The library project is referenced by the demo project in the Android settings (as also can be seen in the project.properties file).</p>
  
  <p>I am testing on a Nexus 7 device with the current Android 4.2.2 version, and the current Google Play Services version 3.1.36 (669520-30).</p>
  
  <p>What could cause this Could not find google-play-services_lib.apk message?</p>
