just for fun, i hacked together a simple prototype of quran search on android. in reality, it’s more close to the autocomplete transliteration demo that i did some time back. for now, it’s only transliteration search, but later on, it can be expanded to search other languages. ultimately, it should probably be integrated into quran android.
you can find the source here. (update: added a link to a tar download and removed the code from github since i am not really maintaining this - june 26th, 2011).
