December Android Security Bulletin
The December 2016 Android Security Bulletin has been published along with links to associated fixes. In addition, new build numbers have been published for Nexus 6 running Android 7.0 and Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, and Nexus Player running Android 7.1.1 to support the December Android security release.
Retail Demo Mode
Android 7.1.1 includes system-level support for retail demo mode to offer a quick, safe, and consistent demonstration of an Android device and significantly reduce the cost and complexity of a retail mode for manufacturers.
Android 7.1.1 includes a night light feature that reduces the amount of blue light emitted by the device display to better match the natural light of the user's time of day and location.
Android 7.1.1 allows developers to define action-specific app shortcuts to let users quickly start common or recommended tasks.
Android 7.1.1 supports circular app icons that can be enabled with a small configuration change.
ART Memory Optimization
Starting with Android 7.1, two options are provided for controlling how
memory is used when compiling everything besides the boot image:
dalvik.vm.dex2oat-swap. See the dalvik.vm Properties
section of Configuring
ART for details.
