Crosswords should not be built with gradle
Users have been reporting problems with recent Crosswords releases from f-droid (I'm the upstream author.) It looks from the metadata as if you guys switched to building with gradle, something I made possible for debugging but that hasn't been tested for release builds. Turns out it doesn't work. Please revert to using ant. I've pushed a new "release" to Sourceforge that breaks gradle release builds to make this clear.
