An application that hosts a set of other applications

I have half a dozen apps that i want to put on Google Market. One of them are ready and the other are in progress. All these apps are kinda related - like a suite of apps, you could assume. So, i was wondering if it would be better to have a separate app (in addition from the half a dozen apps i wish to develop) and have it serve as a LIBRARY-app where users can find, purchase and launch the half a dozen apps.

This is conceptually similar to the Google Books free app where the app serves as a library and users can browse for other books from within this app and purchase it. The only difference is in my case, it would be other fully f开发者_运维问答unctional independent app instead of a book.

Is there a better way to approach what i am trying to do? Basically, i need an app that can host a set of mutually independent apps.

If yes, how do i "host" one app inside an app?

Thanks in advance.
