As Google states, “This is a preview version of the Android system image, and is subject to change. Your use of this system image is governed by the Android SDK Preview License Agreement. The Android preview system image is not a stable release, and may contain errors and defects that can result in damage to your computer systems, devices, and data. The preview Android system image is not subject to the same testing as the factory OS and can cause your phone and installed services and applications to stop working.”
