Ahead of Google and Apples annual developer conference this month, Flurry has taken a look at developer support for each of the worlds two largest app platform providers. With 69 per cent of apps built in Q1, 2012 being for iOS, it appears that Apple still holds the allegiance of the developer community.

Its no surprise to anyone that Apple dominates the Tablet category, where the iPad accounts for 88 per cent of user sessions, with Samsungs Android-powered Galaxy Tab a very distant second at 9 per cent.

Flurry thinks this is among the reasons iOS is more attractive to developers, given that apps built for iOS also run on iPad. “Not only does Apple offer a large, homogenous smartphone base for which to build software, but also when developers build for smartphones, their apps run on Apple’s iPad tablets as well,” says Peter Farago, Flurrys VP marketing, in a blog post. “Thats like getting two platforms for the price of one. Apple offers the most compelling ‘build once, run anywhere’ value proposition in the market today, delivering maximum consumer reach to developers reach for minimal cost.”

Android, meanwhile, offers fragmentation in terms of both hardware – which is split across a range of devices and OEMs – and firmware. The majority of Android devices in the market, at 70 per cent, are running on Gingerbread (aka v2.3), only the third newest iteration of the OS. In second place is the even older Froyo (v2.2), at 16 per cent, which has a larger share than the two most recent versions – Honeycomb and Ice Cream Sandwich – combined.

But perhaps most important is the question of revenue. Based on the top-performing apps on the two platforms, Flurry calculates that the revenue generated per active user is roughly four times greater on iOS than Android – that means that for every dollar a developer earns on iOS, he can expect to earn 24? cents on Android.
