Cor mentioned that he hasn't seen any update notifications for the Android Viewer (which he's installed via Google Play). If there haven't been any updates recently, then this may not be an issue. Because of the limitations on what metadata is provided, perhaps we can list when builds are made available.
Cor: Here's some info from miklos: "Last build was on Friday i think. in the about dialog, you can find the git hash, then 'git show <hash>' shows the exact date (just like for desktop builds)" If your builds is older than last Friday, but hasn't prompted for an update, I'll do some checking with other Android users.
Hi Miklos, (In reply to Robinson Tryon (qubit) from comment #1) > "Last build was on Friday i think. in the about dialog, you can find the git > hash, then 'git show <hash>' shows the exact date (just like for desktop > builds)" https://gerrit.libreoffice.org/gitweb?p=core.git;a=commit;h=3ac52a60d570fb8afb3d8ad063e35f0667b385cb shows it's from Wed, 14 Jan 2015 01:09:05 +0100 (09:09 +0900)
there are very infrequent updates because of the limits imposed by the appstore, like the 50MB limit and of course the overall stability of master :-) Both things did change, google doesn't enforce 50MB anymore, and I found a hackaround for the most frequently reported crash in appstore, so I'll upload a new version soon → worksforme :-) (for TDF)
