Recently, Google officially released the Android 12 developers preview. Presently, some developers can experience the features that this new system brings. The Android 12 comes with support for AVIF format images. Furthermore, it is compatible with AVC video encoding and optimizes the notification interface. With the release of Android 10, we experienced Google’s full-screen gestural navigation system. However, it still faces many problems when using it.
Since most of the current mobile phones have full screens without any physical button, the gestural navigation system becomes very important. Users have to rely on sliding right or left from the edge of the screen. However, this can lead to false triggering of buttons and functions in some app. Google has since acknowledged this issue and it is doing something about it. According to recent reports, the Android 12 developers preview comes with a feature to solve this issue.
Google to use machine learning to enhance sliding gesture performance
Google is trying to use machine learning to try to predict the user’s intentions and avoid false touches. A developer named Quinny899 found a file in the TensorFlow Light module, listing the names of 43,000 applications. The developer suspects that this is a list of applications that Google uses machine learning models for training. The system will detect the start and endpoints of the user’s sliding, try to find the pattern, and determine whether the user intends to return or interact in the application.
At present, the Android 12 system UI has confirmed that this “smart gesture prediction” function is included. Once it is turned on, the system will judge gesture operations based on multiple indicators. As of now, this feature is not active by default on Android 12. Also, because Android 12 is only in its development phase, this feature is “closed” for now. When Android 12 is stable enough for public testing, we expect this feature to be active by default.
Android 12 will get rid of the annoying notification feature
In addition to the interface changes described in our previous posts, Android 12 users will get rid of one rather old and annoying feature of the notification system. For many years the strange behavior of some applications (in particular, Twitter) has taken place: when the user clicks on the notification in the notification panel, nothing happens, and after a few minutes the application starts by itself, with a large delay.
Under the new rules for the behavior of notifications in Android 12, Google prohibits applications from using such a delay, known as “notification trampoline”, and requires developers to change the notification system of their applications to the new rules.
