On the test of the DemoGPGS29 program I get this error in the connection:
NetworkInfo.onConnectivityChange: [type: WIFI[], state: CONNECTED/CONNECTED, reason: (unspecified), extra: "xxxxxxxx", roaming: false, failover: false, isAvailable: true, isConnectedToProvisioningNetwork: false]
GPC_onConnectivityChange: NetworkType=1 IsConnectedOrConnecting=true
Connect: state = Disconnected
Connect: first attempt
Connect: isGooglePlayServicesAvailable returned 0
State change: Disconnected -> Connecting
java.lang.IllegalStateException: A fatal developer error has occurred. Check the logs for further information.

I can't find a solution to this problem.
I followed the recommendations of the tutorial. The only differences are
JDK1.8, android-22\android.jar.
Thank you for your help

Solved.
Error on my part in the manifest.
I'd replace "APP_ID" by the ID of the app.
