Hello Wikimedia

I have a question regarding the open source server and android code available from wikimedia, specifically those at the links below:

Server side: https://www.mediawiki.org/wiki/Download

Android: https://github.com/wikimedia/apps-android-wikipedia

I want to host my own wiki using the mediawiki source on a server. I want to ask whether the open source wikipedia app allows connection to mediawiki servers not owned by Wikipedia.

Thanks,

Amit
