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.

    • SSJ

      S and SL are basically the same hand sets with very minute differences. So expect the update. I am expecting it too. :-)

    what about xperia z1 ?

    If Sony continues to be as developer-friendly as these initiatives suggests it wants to be, it will soon become the standard and **best** recommendation for an Android device manufacturer.

    Such an enlightened approach with full AOSP source code (in addition to the mandatory kernel source code) underscores Sony as a company willing to make devices that are BEST FOR END USERS.

    Availability of full AOSP source code for a device also enables support for end users to wrest more control of their personal devices and data away from the vested interests of over-bearing mobile carriers and assorted faceless corporations.

    Now, if only Sony can commit to always having (at least one high-end/mid-range a la Xperia SP*) models with replaceable batteries AND micro sd card support….

    * The only chink in the Xperia SP’s armor – for it’s market placement – is that it’s battery can’t be user-replaced. That makes the Galaxy S3 more attractive for those who value such features. The lack of developer frendliness from Samsung however is a showstopper!
