How can different android apps work together?
<p>In games like Oblivion there is a thriving 3rd party mod/plugin world. You can get mods for practically every aspect of the game.</p>

<p>How could I write an android game so that I could support additional content written by 3rd parties (which they could charge for in the app store)?</p>

<p>Basically there'd have to be someplace that mods registered their existence and the game would have to check it and then somehow either load data from them (for purely data based add-ons) or execute them (for behavior changing add-ons).</p>

<p>To start with I think I'd mostly be interested in having add-ons which are data (it'd be safest), but I'd like to keep an eye toward executable add-ons.</p>
