The reproducible build process in FDroid is still quite new and raw, but works
at the core level. Its still too raw to really be properly documented, but
here are the working documents:
Guardian Project has 3 apps now that build reproducibly, according to the
JAR/APK signature: Lil' Debi, Checkey, and LocationPrivacy. They are all
quite close to reproducibly building the same hash.
The good news is that we just nailed down a little funding for more related
work, so I hope to have this situation much improved by the end of June.
