How I want to do this, I have a common project, the activity of this common project should be able to trigger the actions of two other projects, depending on various events, for example, on a particular button press, etc. How can i do this? Is this possible with intent?

In addition, the actions of two other projects should be able to challenge each other. How to do it?

If you want to call the MainActivity of a project from an existing project and vice versa, you can use the PackageManager class

        Intent i;
        PackageManager manager = getPackageManager();
        try {
            i = manager.getLaunchIntentForPackage("Target package");
            if (i == null)
                throw new PackageManager.NameNotFoundException();
            i.addCategory(Intent.ACTION_VIEW );
            startActivity(i);
        } catch (PackageManager.NameNotFoundException e) {

        }
