Explaining the software upgrade process and its improvements for Android 4.3

Sony has been rapidly gaining fans in the third-party Android community as they lead contributions to the AOSP and collaborate more openly than other OEMs who trivialise the GPL (like Samsung and HTC). Here, Sony explains their process for rolling out an OS update and rolling patches back into AOSP, and onto Github. 

If you’ve wondered why it takes so long to roll out OS updates, it’s worth a read. It’s also worth mentioning that system-level updates now take a back seat to Google-provided core app functionality from the app store, which neatly sidesteps these issues. See here for more – http://goo.gl/5p5ErZ.

”The PDK is a collection of source files and software binaries that enable device manufacturers and chipset vendors to port their drivers, develop, optimise and test against a new Android release before it is publicly released. The Android PDK includes a set of interfaces for the Android hardware abstraction layer (HAL), platform sources for integration, and a binary system image. The PDK also includes HAL and integration documentation and the Android Compatibility Test Suite.”
