Open game in game app

I need open game in game...

What i mean : Open the app: GTA V

Now go to 4th button (game pad). And when we click on game icon i want to open the game (this game below gta window ( brick destryer) ). I also need to get point from this brick destroyer to pandachii.

Pandachii game is on file : js/main.js - http://nwstudio.esy.es/panda/js/main.js

Brick Destroyer is on file : js/brick-destroy.js

Also when we open this game brick-destroyer the gta must be running in background (still alive).

This game will be emulated to android app with some framework.
