Sony might not be the biggest player in the Android world, but it’s still one of the best choices for those that are looking for devices that are extremely developer friendly while also rocking a premium build quality and design.

What makes Sony truly developer friendly is their willingness to help out the developer community wherever possible. Case and point, Sony has now officially released Android 4.4.1 KitKat AOSP device trees, binaries and build details for numerous Xperia devices.

Specifically covered are the Xperia L, Xperia Tablet Z, Xperia Z, Xperia ZL and Xperia S. That’s a pretty diverse list, with the Xperia S being an older handset and the Xperia L representing the entry level market.

The source releases are very much alpha releases and therefore bugs are to be expected, though most of the basic functions are said to work just fine. In other words, AOSP KitKat might run on the above-listed devices with a little bit of technical know-how, but the releases are more than likely unsuitable for use as a daily driver.

The real significance of Sony releasing AOSP source is that it further opens the door for custom ROM developers, making it much easier for them to bring KitKat goodness to Sony Xperia users. It’s also nice to see that Sony is continuing to actively support the custom ROMing and modding community, instead of working against it.

For developers and advanced Android users looking to learn more, you’ll want to head on over to the Sony Developer AOSP page for more details.
