Just tried out the AndStatus app on Android. I successfully added accounts for pump.io and Titter, but adding this Mastodon account failed. I tried adding a Friendica account as a GNU social account, since it supports OStatus and I can't see any other way to do it, but that failed. I don't think I have a GNU social account since the Quitter. sites went down, but I'll have to check and maybe set up a new one for testing purposes.
