Adding libgdx to an Android Native Application

Question

I have a simple kids app which teaches things such as colors, numbers, etc... which I am currently developing. It uses what I would consider \"standard android java programm

Answer 1

In Libgdx your entire game is just a single Activity. You can start it as any other activity from your code. Please follow Can I run an Activity before running libgdx? for details.

Answer 2

You can integrate your App with your libgdx game.
AndroidLauncher.java is your libgdx Activity and you can move from one activity to another using Intent.

intent = new Intent(this, AndroidLauncher.class);
startActivity(intent);

and movement from libgdx AndroidLauncher.java, you need to call it from inside the core project classes. You need to use an interface.

If your game is sub view of your App.
The AndroidApplication class (which extends activity) has a method named initializeForView(ApplicationListener, AndroidApplicationConfiguration) that will return a View you can add to your layout.

Pros.-Code is already you have,only you need to integrate.
Cons.-you need to maintain OpenGL Context Loss. Libgdx do for you.
