We've pretty much ceased to bother with Android, apart from occasional updates to the 3 titles currently on there. The reasons for this:
1) The service is absolutely swarming with crap. There are certain developers that specialise in cyclically releasing virtually invisible updates to their collection of match-3 games every 2 weeks just to stay atop the "just in" list as much as possible. There are hundreds of apps using the name of well-known film or TV shows, musicians, whatever it takes to get search results. There are apps which are basically the name of well-known iPhone games, followed by a lot of spaces, followed by "... Wallpaper". There's a dog fighting game on there. It's not a healthy and competitive market, it's a morass.
2) As a result, most Android users just look at the "Top" section, but that just means that those titles which already sold ungodly numbers sell more. Everyone else is ignored.
3) There's no practical way to market a game to Android users. There isn't even an equivalent of "freeappaday".
4) Android is supposed to be a blanket solution across multiple handsets, but apps have a horrible habit of randomly not working on some handsets when they work fine on others. This gets much worse if you use anything remotely complex such as wifi, bluetooth, or even the Contacts API.
5) Android users don't email to tell you it doesn't work. They give you a 1 star rating and post a comment to that effect. Neither can ever be removed, even if you fix the problem. This routinely happens due to point 4), above.
6) Android users consider £1.50 too much to pay for a game that took multiple people over a month to create, and get angry if the game they bought for 80p doesn't get updated every single month with new content.
So, as you can probably tell, we're not going back there unless someone pays us to, except to bugsplat our existing apps. It just isn't worth the time and effort.
