First off your going to need unity remote on your android device, this lets you get touch input information live as you press play on your game.
Secondly just because its no code doesn't mean it will be a walk in the park, watch some tutorials (There are lots of youtube videos and links on the forum) and try and make some basic games on your pc before going onto your phone because your going to need at least a basic knowledge of playmaker before hand.
Playmaker is a fantastic tool but take the time to learn how it works before venturing on to android development
Trust me, i made the same mistake when i first purchased playmaker.
Good luck!
