Start games in android

Question

I have a PAC MAN game code how to name this game in android as activity .. and I want to call an online game in an Android application, than how to call online games in an Android application using the link if the user clicks on this specific link on a game than online games on the net such as PAC MAN. thanks

Answer 1

You cannot just “call the game code”. You can learn, understand and reuse logic and create a new game in Android. Even reusing this code will require a lot of refactoring.

If you want to create games for Android, you can use a framework like Cocos2D.

Here is a good tutorial:
