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).
