First of all, Android is much harder to develop for than the iPhone.
As someone who's published apps on both platforms, I'll disagree with that. For me the occasional extra effort it takes to support multiple resolutions and OS versions is more than made up for by being able to use a semi-modern language. (Preemptive response: Yes, I know Objective-C well, and non-enterprisey Java beats it hands down).
Well maybe it was my mistake to generalize (and say "much"). And by develop, I meant develop, test, support, and maintain over a wide range of phones and capabilities. These issues may be more or less pronounced based on what the app does and the size of the user base.
