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 programming (Single Xml/java class)." I also have a simple game with a Dinosaur that jumps over letters using libgdx.

My question is, I would like to have the game as part of the "overall" app. I would like to know if it is even possible to add a libgdx game to an android native application. I tried adding the appropriate files to my app, but this caused a compile error, could someone point me to a place where I could find help on this issue, or perhaps let me know if what I am wanting to do is even possible? Thanks.

---To clairify, my main app has a menu which takes you to activities. I would like the libgdx game to be one of the activities.

---Edit to response---I compile using Gradle and have more errors than I can count. I've since removed the libgdx game from the app so I am not sure of specific errors, but iirc there were over 100, many of which were R issues, which I could have figured out, but I couldn't find anything on either S.O. or the web saying it was even possible to add libgdx to a non-libgdx app.

Answer 1

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.

Answer 2

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.
