Different animations on mobile

I started to make my game on Android and iOS and using Unity 4.2! But I want different animations for my character(idle, walk, run, etc.). I have all animations in .fbx files but I don't know how add them in my game (for example: if I drag joystick my character's animation changes- this is result I want) I tried to use Macanim but that did't work! Maybe there is another way to do it or there is an example project with MOBILE animations?
