Zurichess is using city names from Switzerland in alphabetical order to track versions. The last build for Android was Geneva and it was compiled by Jim Ablett. Following his (temporary?) hiatus, the author Alexandru Mosoi has kindly included a Linux-arm build of his latest release.
In contrast with my first statement, it appears that Linux-arm build runs okay with Android. So, there's nothing left to do but start using it because accordig to Alexandru, Graubuenden is scoring +110 ELO in self play against Glarus, which is supposed to play better than Geneva (2360 ELO in Rapidroid).
