How to release application plugin using Android Market?

Question

Could someone describe me a solution to implement a plugin inside an Android application and how could it be sold on the Android Market?

Typically, you create a game

What I've seen so far on the Android Market are entirely different version of apps for free versus paid content of the same application.

I haven't looked into plug-ins yet so I don't know if this feature is available, but if you can't find it a workaround could be to launch applications and hide them from the add application to home menu and/or shortcut menu and just add a link to it inside the main application.

Another workaround is to treat your additionnal content like paid content libraries and simply block the level access if the resource is not accessible. But you have to verify if you have a right to have private librairies that are separate from your application.

Basically what you're looking to do is exactly what content hosters like Apple and Android are trying to avoid or control since it would allow you to stream new content to your app without the content host knowing it's actually new content for another app.
