i've been following the tutorial in Creating an Endpoints Backend from an Android Project. Everything is compiling and looks promising. The backend is up, i changed CloudEndpointUtils#LOCAL_ANDROID_RUN to 'true'. but when i try to test the app on a real device (not emulator) im failing on -
java.net.SocketException: failed to connect to /10.0.2.2 (port 8888) after 20000ms: isConnected failed: EHOSTUNREACH (No route to host)
java.net.ConnectException: failed to connect to /127.0.0.1 (port 8888) after 20000ms: isConnected failed: ECONNREFUSED (Connection refused)
as the app engine server address parameter to accept from all incoming connections.
