Starting up help

So im just starting up on unity and im planning to make a game more andriod devices but I was wondering how I should start! I have downloaded the STK and everything but what happens now? Do I need to learn a differnt type of code for controls and stuff to be able to work on the devices? Is there like a basic platform I can base it off?

Thanks

There are tutorials Learn

You can start with making a game, testing it on your computer, keeping in mind that at some point you would want touch controls.
This makes it much easier to test and prototype within the editor (you can even test in the editor with Android selected as the platform).

Start with a controller class, that understands the unity Input class, get the Axis and buttons you want for testing on PC (just dont use ctrl or alt within the editor, as it still controls the editor as well) then later add the controls for Android.
The main benefit you could get here is that your game would easily work with physical buttons and bluetooth controllers, which most don’t have but is a good strength to add to any game.

There are many examples in the asset store, even complete projects made by the Unity team with tons of resources to take a look at.
I would recommend focus on you game first, learn how unity works, then later down the road, figure out how to build for android and adapt the controls.

C# or java would be your best options for support if you stumble upon any problems.

Input.touches gives you all the touches

Hope it helps
