What exactly did Android N upgrade?

Recalling that Google's actions in Android improvement over the past two years are more about system security and performance enhancements, the major change in this generation of systems compared to the previous-generation Marshmallow system is the addition of split-screen multitasking. Picture-in-picture functionality, more convenient notification centers, notification messages, and efficiency improvements.

1. Add split-screen multitasking

Android N natively supports split-screen multitasking, allowing users to use multiple applications simultaneously on one screen. After the user opens an application that he wants to use on the screen, and then presses the bottom square browse button, he can choose to add other applications to the screen. Native support means that the application can use this function without updating. .

2. Speed increase

Android N's code is reduced by 50%, and the new compiler Clang+LLVM has a 100% faster compilation speed; it also speeds installation and download speeds. Android N operating environment has been significantly improved, the speed of software upgrades to reach 600%, application installation speed 75%.

3. Native support VR

At the I/O 2016 Developer Conference, Google mentioned that Android N will be the first mobile phone system to support VR natively, and at the same time it will launch a “daydream” VR platform. Many VR applications and games will be developed based on this platform in the future. It has great potential.

4 native support 4K core

Android N for the first time for the full upgrade of all 4K products, such as the first time on the Android native system supports HDR, VR, PIP and other 4K value-added services development, interface standardization provides unlimited innovation possible; the first use of JIT + AOT optimization technology, Clang + The LLVM compiler and Vulkan development interface make the Android N system more fluent than IOS.

5. Notification message quickly reply and gather

The notification bar has also undergone major innovations in Android N. A new API has been added to support the quick operation and reply of third-party application notifications. For example, an incoming call will appear at the top of the screen as a banner, providing two buttons for answering/hanging up; Social application notifications can also open the keyboard directly and respond quickly in the input field. In this way, the icon takes up less space and is more compact. Pressing the notification will pop up the corresponding notification setting option. The new design simplifies the user's operation logic and is very convenient. In addition, Android N merges multiple notification prompt messages of the same application into one item, click this item to expand all previous notifications, and allow the user to perform a separate operation for each notification, which is very convenient.

6. New setting style

Android N enables a completely new set of styles. First, the dividing line between each sub-item under each category disappears. Only the dividing lines between categories are preserved. The new setup menu also provides a green top bar that allows the user to quickly set the Do Not Disturb mode via the pull-down arrow at the rear. In addition to the Do Not Disturb mode, the top bar menu can also display many other settings, such as the use of data traffic, whether the automatic brightness is on, and so on. In addition, the hamburger menu is added to the settings. In the upper left corner of the secondary setting screen, you will see the hamburger menu. After clicking, you can see all the setting items, so that the user can jump quickly.

7. Brand new pull-down shortcut switch page

In Android N, pull down to open the top of the notification bar to display the shortcut switches commonly used by 5 users, support click switches and long press to enter the corresponding settings. If you continue to pull down the notification bar, all shortcut switches will be displayed, and an “Edit” button will also be displayed in the lower right corner of the shortcut switch page. After clicking, you can customize the Add/Delete shortcut switches or drag to sort.

8. Join the night mode theme

Android N rejoins the nighttime dark theme mode. The user finds the "system tuner" setting in the settings, clicks on the "color and appearance", and can find the night mode. After opening, you can use the global dark color. Theme mode, with simultaneous brightness and color adjustments, can be automatically turned on based on time or geographic location. In addition, RGB red, green, and blue trim sliders are also provided in the system tuner, allowing the user to fine-tune manually, such as reducing blue or increasing red to provide an eye-protecting look.

9. Traffic protection mode

The new traffic protection mode of Android N not only prohibits the application from using traffic in the background, but also further reduces the traffic usage of the application in the foreground. In addition, Google has expanded the capabilities of the Connectivity Manager API to allow applications to detect whether the system is enabled for traffic protection or whether it is on the whitelist.

10. Improve the Doze sleep mechanism

Google has further optimized the Doze hibernation mechanism in Android N. In previous Android 6.0, the Doze deep hibernation mechanism provided a great effect to improve Android's life. In Android N, Google has made more optimizations to Doze. The usage rules and scenes of the hibernation mechanism have been extended. For example, if you manually delete an application card in the background, the application will be deeply hibernated soon after closing the screen.

11. System level telephone blacklist function

Android N turns phone interception into a system-level feature. Other applications can call this intercept list, but only individual applications can write, including dial-up applications, default SMS applications, and so on. Intercepted numbers will not appear in the call log and no notification will appear. In addition, the user can also backup and restore this interception list through the account system, so as to quickly import other devices or accounts.

12. Menu key quick application switching

Double-click the menu key to automatically switch to the previous application. In addition, if you keep clicking the menu key, it will rotate continuously in all applications, the application window will automatically enlarge, there will be a countdown bar at the top, stop clicking and after the countdown is over, the current application will automatically enlarge and return To the front desk.

13. Keyboard theme

Android N's own Google input method will have many themes to choose from. You can even set up custom photos. The improvements are all in details, but they are also very intimate.

14. File-based encryption

Previously, the Android operating system can use the method of encrypting the entire disk to encrypt the mobile phone. In this case, the user's mobile phone is often encrypted into a giant unit. Today, with the support of the Android Nougat system, the user's mobile phone can encrypt individual files, creating a more active security system.

15, save data function

Applications running in the background can consume users' monthly data and traffic very quickly. By saving data functions, Android Nougat system allows users to stop the application running in the background to better protect the previous data plan. Android N allows users to choose whether to turn on data protection mode for each application.
