epublib
Epublib is a java library for reading/writing/manipulating epub files.
I consists of 2 parts: a core that reads/writes epub and a collection of tools. The tools contain an epub cleanup tool, a tool to create epubs from html files, a tool to create an epub from an uncompress html file. It also contains a swing-based epub viewer.
The core runs both on android and a standard java environment. The tools run only on a standard java environment.
This means that reading/writing epub files works on Android.
Command line examples
Set the author of an existing epub java -jar epublib-3.0-SNAPSHOT.one-jar.jar --in input.epub --out result.epub --author Tester,Joe
Set the cover image of an existing epub java -jar epublib-3.0-SNAPSHOT.one-jar.jar --in input.epub --out result.epub --cover-image my_cover.jpg
