ProGuard 4.4 is doomed 
The first release of CacheTrack 1.9 was broken. The binary you can now download is fixed. The problem was that this version wasn't able to draw OSM maps anymore.
The problem wasn't my fault but was caused by ProGuard 4.4. In the past I used version 4.2 which worked pretty well. Now I switched back to version 4.2 and everything is fine again.
So if you (as a developer) run into problems with your obfuscated production code try to use version 4.2 of ProGuard and save yourself of a lot of trouble.
