Android App - Way to develop app that has add-ons
<p>Is there an outline or primer of how you would develop an app that has "add-ons"? Let me explain. Basically, how to develop some sort of framework for adding "themes" to an app.</p>

<p>There is basic app with 2 themes.  I want to have another app that you can download in the market for a certain theme.</p>

<p>How does the original app and the new downloaded app talk together? How would you develop the original app to get the theme information and graphic assets from the 2nd theme only app? My understanding is that apps are completely separate so this is why I am unclear how to accomplish this.</p>

<p>Any help in understanding the Outline of the process as well as maybe a small example would be greatly appreciated.</p>

<p>Thanks</p>
