I recently had a HUGE discussion with a couple of friends directly related to this situation. There are a number of devs who are touting the joys of the Android environment, and how it's a myth that nothing sells on Android... and then there is the problem with vetting devs on the Google Play Store, as it is possible to register with an identical company name to an existing developer, and post the same-named game up on the Store, for free. It allows piracy to flourish, even as the people pirating the games may just think they're downloading the trial version of the game, etc.
So, yeah, Android's not a priority until that gets in a bit better shape.
