The official version of Android 8.0 has just been released, and its share is only 0.2%. On October 26, Google released the Android 8.1 developer preview version, which can be upgraded as early as 2015, including Nexus 5X Nexus 6P、Pixel C、Pixel、Pixel XL、Pixel 2、Pixel 2 XL。
Major upgrades include:
Neural Network API (NNAPI), specially prepared for machine learning library and framework, provides hardware acceleration function of machine learning. On Pixel 2/2 XL, developers can call their Pixel Visual Core (NPU) to process HDR+. However, Google also said that ordinary applications will not call new APIs, and perhaps the upgraded Huawei Mate 10 with NPU will have a greater improvement effect;
Notification bar: the notification message will only emit a prompt tone once per second, and some low memory devices will lack some notification functions;
Improvements for low memory devices: Android 8.1's API Level is upgraded to 27, and two hardware feature parameters are added. Developers can provide another set of settings according to the memory size, but the developers still have to adapt;
Automatic filling function optimization;
Text editing;
Safe browsing behavior: allow APP to conduct security detection on browsing behavior and avoid threats;
Video thumbnail: the previous thumbnail will change due to the size of the video, but now it will not. There will not be a 4K video result to generate a 16M thumbnail, which is a painful thing;
Shared memory API: API level 27 introduces a new SharedMemory class. Multiple processes or applications can create, map, and manage anonymous shared memory (perhaps saving some memory);
Wallpaper color API: developers can make the notification bar and virtual keys automatically turn black or white according to the depth of the wallpaper;

The upgrade method is to unzip the flash package to the new flash environment folder and click the flash all batch file. Although our Pixel 2 can enter the system without going over the wall network after the official version of the machine is cleaned, it is recommended to prepare the wall network first.
