In the early hours of Beijing March 8th, in recent years, Google releases the next developer preview of the next Android system in March. This year's release is the next generation of Android systems, codenamed Android P. The highlights of the new system include the improvement of the notification bar, the optimization of the indoor location, the design of the top notch screen like the iPhone X, and the performance improvement.
The developer preview is for Android developers only. Google hopes to get feedback from developers about new functions such as new type screen adaptation and new notification bar in preview system.
New features for applications and developers
With many new mobile phones using similar Essential Phone and iPhone X similar to the design of the screen top groove, the current mobile application can make full use of this unique screen for application design. The Android P system adjusts the design of the notification bar to match the screen, and the new APIs will allow developers to determine the form of the notification message.
The improvement of notification bar improves functionality and visibility. That is, applications can not only display static notifications in the notification bar, but also display real-time conversations, pictures, expressions and other contents, and can directly reply to messages. Reply, a message similar to Google's experimental nature, is used.
