The best Android Google Reader client has added beta support for tt-rss! Here is a link:https://groups.google.com/forum/#!msg/g_reader/OlsVd9RSfPU/n2mgtTyT88oJ
BTW, the official tt-rss Android client is very good. The fellow doing gReader only had to build a client. Fox has built the server side, web client and Android client. Essentially Fox has done pretty much all the Google did on Google Reader and built a pretty damn good Android app. AND, despite his sometimes being grumpy he actually supports tt-rss, something Google didn't do much of on Google Reader before they canned it.
Fox, sorry if it pisses you off but note the comment about the limit of 60 results being returned by the API slowing down things. This guys has spent a lot if time on making a great app and he knows the user expectations. If I remember correctly, Google had a 200 items per request limit. maybe you could optionally allow the limit to be bumped to see if it does indeed help speed things up.
