So Minecraft Pocket Edition is written in c++. What apps (android) can I use to open the code and be able to modify some codes to change the skins etc? Thanks.

Answer 1

you need the source code, getting the source code for minecraft would require you to eather work for the company, or a likely fellony convection for stealing it with some socal engineering technique or crazy hacking

Answer 2

I don't know this game, but i think you cannot.
You have to have the code to change it, if you have only the software compiled you have to decompile it. I think it is a very hard procedure, and almost certainly illegal.
You have to know the license, and ask the author of the game to give you the code.

Answer 3

Oh ok. Thanks for your answers.
