Android 4.2.2 is out, and while an OCD-fueled 4.2.2 edition of Getting To Know Android is on the way, we figured it would be a good idea to highlight the big user facing changes that came with this release. We already covered the new ADB Whitelist and posted the raw developer changelog, so this should be the last of the important stuff.

New Download Notifications

First up is the new notification for in-progress app downloads, which now shows the percentage and an estimated time remaining for your app downloads while they are happening.

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.

Worried about an ADB-savvy thief stealing the precious data off your stolen phone or tablet? Well, Android 4.2.2 makes doing that a little harder now, with the addition of a USB debugging whitelist feature into the OS. The way it works is pretty simple - when you connect your PC to your Android device via USB, Android gets your PC's RSA key (an identifier token). In Android 4.2.2, when you have USB debugging enabled, this now causes a prompt to appear on connection, seen below.

It's begun - the newest version of Android, 4.2.2, is being pushed to AOSP right now. We saw the accompanying Nexus OTA rollout start last night, with update files slowly springing up thereafter. Right now, 4.2.2 builds can be downloaded for the Takju Galaxy Nexus, Nexus 7 (Wi-Fi), and Nexus 10.

The build number is JDQ39 and the tag in AOSP is android-4.2.2_r1. Here are a few of the many directories that have been updated:

While the push has just started this morning, source will likely continue to show up throughout the day, and we'll update this page as that happens.

While the official OTA update to Android 4.2.2 began rolling out to the Galaxy Nexus, Nexus 4, 7, and 10 last night, you may not have received it yet. We already posted a link for the Galaxy Nexus takju build, but now we've got a couple more to share.

Update: JDQ39 from JOP40F for the Nexus 10 added.

  • Nexus 7: Android 4.2.2 update (JDQ39 from JOP40D, 47.7MB) (Note: Wi-Fi model only, aka grouper/nakasi)
  • Nexus 10:

Your device needs to be running the JOP40D build in order to flash the updates, doing so from another build will probably just fail, but we wouldn't attempt it either way.

If you're currently dissatisfied with the selection of lockscreen widgets for Android 4.2 devices, a fantastic new entry from Android Engineer Roman Nurik just hit the Play Store. It's called DashClock Widget, and it's one of the cleanest, best-integrated widgets we've ever seen.

DashClock Widget combines many of the most common widgets – Gmail unread count, weather, calendar, missed calls, text messages, and alarms – into one clean, sophisticated, customizable widget.

A couple of hours ago, Google started rolling out the Android 4.2.2 update to a very limited subset of Nexus devices (build JDQ39). At this point, almost nobody can get the OTA pulled by going through the Settings screen, but don't worry - one of our loyal readers extracted the OTA url for the Galaxy Nexus and sent it over to us (great work, Daniel Koch!).

For now, we only have the link for the takju Galaxy Nexus variant, i.e.

Nexus owners may have a reason to stay up tonight, as a couple of Reddit users report that Android 4.2.2 has begun rolling out to the GSM Galaxy Nexus and the Nexus 7.

There's not much word regarding what the update (which carries build JDQ39) includes just yet, but readers may remember that Google promised a Bluetooth A2DP audio streaming fix in the "next release" of 4.2 after 4.2.1.

Earlier this week, we got wind of a new OTA build JOP40G possibly hitting the Nexus 4 soon. I thought this update would finally be the elusive Android 4.2.2 that we've been hearing about, but it looks like that's not the case.

Yesterday, Google pushed some new open source code to AOSP (Android Open Source Project) marked with 2 new tags: android-4.2.1_r1.1 and android-4.2.1_r1.2. The build number corresponding to the 4.2.1_r1.2 release is - you guessed it - JOP40G (with mentions of JOP40F and JOP40E along the way too) - the same one we thought would be 4.2.2.

A couple weeks ago, we got wind of a download that seemed to be the final version of Android 4.2.1 (GA02) for the Sprint Galaxy Nexus. Today, not only is that confirmed, but the OTA has begun for Nexus warriors on the Now Network. The update brings the newest flavor of Jelly Bean and all that entails, including Photospheres, Daydream, lockscreen widgets and more.

The release comes about two and a half months after the initial launch of Jelly Bean 4.2 (counting by the launch of the new Nexuses.
