FBReader (aka FbreaderJ) is a very popular ebook Reader on android 10M+ downloads (and many other platforms). Unfortunately a few years back the owners of https://github.com/geometer/FBReaderJ (1.8k stars) decided to stop open source contributions and go only commercial. Their last open source version has been put here: https://github.com/geometer/FBReader-Android-2 (gradle based) As android SDK evolved, the app is no longer compatible with newer versions. The only fork that I know it made some updates for slightly newer sdk few years back: https://github.com/gelojavonitalla/FBReader-Android-2 and https://github.com/aplicatii-romanesti/FBReader-Android-2 Of course, besides updating sdk there is also a list of bugs which are long due (I can provide a list).

As the project was open till now, there were other open apps based on it, and currently unable to maintain both the main project and their own ones.
