System of modules and addons
Many applications in the market offer to download addons as a paid version and after installation they simply add functionality, but are not listed in the installed programs and do not hang in the processes. Question: how to implement such a system of addons and the .apk itself, which unlocks something in the application, but does not install itself (in many cases, it still downloads content for playback).
Examples.
- A trial version of of some kind the player.
- Unlock to it.
More examples.
- Application with a set of sounds.
- Add-ons that download sounds and images and then unlock them in .in the app
I found a check for the installed "unlock": Sharing code. How to make a check for its installation, now I know. But here's how to make this unlock itself, so that it does not appear in the menu and processes during installation?

The solution came to my mind when I was reading an English-language book. Who cares, in the manifest file, the category should look like this
<category android:name="android.intent.category.DEFAULT" />
Then the application will not be displayed in the menu, and you can use it for various checks on the installation of this application from other applications.
