Android M Teardown—tap-to-wake support, Play Services data backup, and more

The Android M developer preview was posted during I/O, and now that I've actually gotten home and had a full night of sleep, I'm cognizant enough to seriously dig into the system images. Back when I worked at Android Police, I would do "APK Teardowns"—basically decompile the APKs that Google puts out, compare the new version against the old version, and see what new things stick out. Often Google would leave work-in-progress features in the code, I'd find them and write them up. Eventually Google caught on and started leaving Easter Eggs for us to find, and I've been told Google now audits code for unreleased features.

While gleaning information from app-to-app updates isn't as fruitful as it used to be, Google did just release an entire OS, so there's got to be something in here, right? Before we dive in, a word of warning: these are hints of work-in-progress features at Google, but that doesn't guarantee they'll ever see the light of day—anything could be cancelled or reworked at any time.

Native Tap-to-wake support!

One of our favorite features of HTC and LG devices is the tap-to-wake functionality. Rather than hunt for the power button to wake the device, you can just double tap on the screen and start using it. In Android M's settings provider there is a new Boolean value called "double_tap_to_wake," which suggests Google is working on getting this OEM feature built into the OS.
