what is the difference in coding for android or pc in unity? what documentation should i look to make sure that my application will be supported in android?
are all c or js script compatible between platform?
You need different code for input, but otherwise it would be the same in most cases.

As eric said, the code itself is the same.
c#, js, all the same.
you just have to make adjustments to the changed hardware.
these changes may include different shaders or image effects, different input solutions(no mouse and keyboard).
so main changes would be to adjust graphics (usually quality and performance on pc are not a big issue as on mobile devices) and the input methods (former keyboard or mouse inputs have to be caught by touchscreen now)
