What markets are you trying to get more in front of? US? Europe? China?

What device levels are you trying to get in front of?

Android seems like a "no brainer" until you start looking at the details... For example, if you cut out all "cheap shit 2.2 android devices" and focus on new(ish) Android 4.0> things get REALLY murky... In the US iOS still holds a lead over Android in those markets; in Europe Android is ahead, but then you have localization to deal with.

Additionally, Android might have an edge in some markets, but the fact that iOS users actually PAY for apps also makes a big difference.

The point is that Android is a sensible choice but it's not an automagic choice, nor is it as cut and dry as it appears.

It really depends on your user/customer. If you have a app that targets a specific customer profile, then the larger market share is not as relevant. You need to try to identify your customer, in specific terms, and learn what kind of phones these people tend to use, among other things.

Is your app primarily for middle-aged women (mom's) living in the U.S.? Is it for teenagers and young adults in the UK? The more specific you can get with your customer profile, the better your decisions will be. The makeup of some user populations can be very different than the broader market. It would be unfortunate to invest in building an Android app, only to find that your soccer-mom customer base runs 80% iPhone (just an example).
