Legendary Pokémon

Basically I'm having trouble figuring out how to apply the coding for the app for a pokemon application on a phone.

Want to make a small game to where you create your own pokemon zoo.
Kinda like the jurrasic park app

Oh man, that's a huge discussion over here. So, for starters, what is your knowledge on Java (not javascript, ffs) or C# or Objective C?

Take a look at free game engines (I prefer Unity).
It's not as easy as you make it sound
