I want to have a minigame inside my notetaking application in android

Question

I want to have a minigame inside my note-taking application. (Eg: an activity with a chrome dinosaur clone.)

I have worked with libktx and libgdx before. My question is can these libraries be used to work with normal android projects and can they be used to interoperate between a normal activity and the game activity?

So in essence i want to jump from my normal activity which takes notes to an activity which will have a minigame inside ..

LibGDX can be embedded in an Android application as a Fragment rather than a complete activity.

From the official documentation:

A libGDX game can be hosted in an Android Fragment instead of using a complete Activity. This allows it to take up a portion of the screen in an Activity or be moved between layouts. To create a libGDX fragment, subclass AndroidFragmentApplication and implement the onCreateView() with the following initialization:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return initializeForView(new MyGdxGame());
}

That code depends on some other changes to the -android project:

1. Add AndroidX Fragment Library to the -android project and its build path if you haven't already added it. This is needed in order to extend FragmentActivity later.
2. Change the AndroidLauncher Activity to extend FragmentActivity, not AndroidApplication.
3. Implement AndroidFragmentApplication.Callbacks on the AndroidLauncher Activity.
4. Create a class that extends AndroidFragmentApplication which is the Fragment implementation for libGDX.
5. Add the initializeForView() code in the Fragment's onCreateView method.
6. Finally, replace the AndroidLauncher activity content with the libGDX Fragment.

For more examples, see the official documentation or this StackOverflow question.

LibKTX should work seamlessly in a Fragment, and you should be able to easily translate the examples from Java into Kotlin if you want to.
