Last week I was speaking at Android Only! 2011 conference in Malmö, Sweden. My presentation was about Android device fragmentation and more specifically on how Android application developers can cope with the current fragmentation in Android devices. This problem did not exist 9 months ago and now it is becoming the single most expensive headache for any serious Android application developer. To understand the full extend of this problem you only have to browse through the comments of any application in the Android Market. About 80% of the comments are about the application not working correctly on a specific phone model, updates that make the application crash or in the worst case the application that the customer just paid for does not install at all.
