Following yesterday's Android 4.2.2 OTAs to various Nexus devices, Google today followed up with the push of all 4.2.2 open source code changes to AOSP. There is a lot here to parse through this time around compared to the minor 4.2.1_r1.2 commit from 10 days ago.

We've already identified some obvious user-facing changes, which we'll post about separately soon to keep it clean and organized. The purpose of this post is, as before, to find the low-level changes that may not be obvious. So move the beard out of the way and dig in.

Update: Ron detailed some new things here: New Android 4.2.2 Features: Toggle From Quick Settings, Better App Download Notifications, and Some New Sounds!

What's New?

Things we've discovered so far, in brief:

Here is the list of developer commits in 4.2.2 (AOSP tag android-4.2.2_r1, JDQ39) compared to 4.2.1's latest revision (AOSP tag android-4.2.1_r1.2, JOP40G).

Note: For whatever reason, some of these we may have seen before - perhaps someone who understands the intricacies of AOSP's git structure can explain why they're getting included in the diff, but for the most part, this is all new stuff.
