How will KitKat solve Android's fragmentation problem?
According to Google's KitKat website, "It's our goal with Android KitKat to make an amazing Android experience available for everybody."
What does this mean for what we will see in KitKat? We still know very little about 4.4. so my only guess is that this means KitKat will do something big to address fragmentation.
Right now, Google believes they can deliver an optimal Android experience to users of Nexus and Google Play Experience devices, but not necessarily on all the devices with carrier and OEM mods that do not receive reliable updates from Google. Fragmentation remains a significant issue for both users and developers, and one of the biggest roadblocks to getting developers to build for Android first.
So what will KitKat do to address fragmentation and provide a great experience "for everybody"? Google's previous attempts, such as the Open Handset Alliance, failed to pan out, so they must have a new approach for making new Android features more widely available to everyone.
One possibility is that we will see big improvements to Google Play Services. Articles like this Ars Tecnica piece make the case that Google Play Services has supplanted Android as Google's "new platform", because it allows them to deliver new API's and features to most Android devices via their proprietary services layer.
Beyond this, I can't imagine what Google can do to deliver on their promise of making "amazing experience available for everybody". What do you think KitKat will do to solve fragmentation and/or make the Android experience better for more people?
