Android’s Rectangle of Fragmentation

This graph shows the challenge that faces Android developers; over 18,000 distinct devices can immediately use their app, making optimization a real challenge. Compared to last year, fragmentation has risen by around 60%, with 11,868 devices seen last year compared to 18,796 this year. Compared to our first report, in 2012, device fragmentation has more than quadrupled – with our first report showing that there were ‘only’ 3,997 distinct Android devices. Another way of looking at how fragmentation affects developers is to see what % of the market is occupied by the top 10 devices – as developers generally only own a few devices to test on. Last year having the 10 most popular devices in the market would represent 21% of the devices out there, this year that number has fallen to 15% – making testing on a few devices less representative.
