I've put together a couple of Android apps in my spare time the last few years which make use of verses of the Quran (Hifdh Tracker and Hifdh Tester). I'm in the process of making the code for these apps entirely open source. As a first step I've just extracted the database and the helper methods for accessing verses of the Quran out of the apps and into an Android library of its own. You can find the code repository for the library here. The README in the repository explains how to incorporate and make use of the library in your own apps.
