Yeah I can give this step by step guide:
1) In the appstore for your device (iOS or Android) search for and install the AppGameKit Player.
2) Run the app, on screen it will give you the IP address of your device.
3) In the AGK2 IDE go to Build >> Build Options and enter the IP Address in the "Device IP Address" box.
Now when you want to test your game/app have the AppGameKit Player open on your mobile device and then click "Broadcast" instead of "Run" in the AGK2 IDE this will compile it and broadcast it to your device for testing.
