[pconline information] Google held its annual Google I / O Developer Conference on May 19. Due to the epidemic situation, the conference adopted the full online mode. Compared with last year’s forced cancellation of the conference due to the epidemic situation, it is a good thing that the I / O conference can be held this year. On Google I / O 2021, Google announced that Android 12, the latest generation of Android system, has started beta testing, including Google pixel, Xiaomi, Yijia and other devices, which can be first experienced through corresponding channels.
Android 12 is a huge improved version from the outside to the inside, so what are its new features? Foreign media Android authority has brought a detailed analysis of the new features of Android 12. Let’s take a look!
Great changes in visual elements
This is the most noticeable new feature of Android 12. In Android 12, the system will use the color extraction mechanism to extract design elements from the set ratio. The visual effect is the main tone of the whole system, which will change with the desktop wallpaper. With this simple and automatic color theme design, users’ mobile phones will become more personalized.
In addition to automatic color theme, Android 12 also has many design adjustments, such as new animation, optimized spacing and so on. However, it should be noted that in the first beta Android 12, automatic color theme is not installed, and the second beta released in June is expected to experience this feature.
New operation center
Maybe Android users are used to seeing the prototype icon in the operation center after pulling down the notification bar. This design has existed in Android for many years. Now, Android 12 will make a big change to this. The operation icon of the prototype no longer exists. Instead, it will be a large patch with rounded rectangle.
The operation mode of these tile buttons is similar to that of the previous shortcut buttons. You can turn on and off the corresponding functions with a light press, and you can enter the setting interface with a long press. But now these tile buttons can take on a larger area and hold more information.
Of course, a larger area also means fewer buttons. After the first drop-down notification, you will only see four buttons instead of the current six. It should be noted that the color of these buttons can also be changed through the new automatic color theme, and the visual effect is very harmonious.
Privacy and security enhancement
In Google I / O 2021, Google announced the new privacy function of Android 12, and the process of APP collecting information will become more transparent. The new system tools allow users to manage app permissions more finely, which allows users to better manage what information the app can access.
Android 12 provides a new privacy management panel, from which users can see the detailed view of APP access information. After opening, you can see relevant details, such as how many apps have visited your location, camera and microphone in the past 24 hours.
In the new privacy panel of Android 12, users can adjust the permissions of an app through relevant options. You can see the settings of administrative permissions on the timeline page, and you can cancel the feature permissions of an app.
Redesign of notification system
Android 12’s notification system will be redesigned to improve aesthetics, usability and functionality. Google is currently adjusting the notification drawer and control buttons, and speeding up the switching response and animation.
In Android 12, the response speed of notification is the key target. Android 12 will guide developers to give up the intermediate broadcast receiver or service. The function of these mechanisms is to let users jump from notification to app. In Android 12, Google wants to bring users directly to the app itself by clicking notification. Google also provides a brief window for short tasks, delaying the display of certain foreground service notifications for up to 10 seconds so that users can complete the operation.
More convenient WiFi sharing
In Android 11, if you want to share WiFi hotspots with others, you can easily do it through QR code. However, in Android 12, the method has been further improved. By clicking the QR code, you can see the “nearby” button, and you can directly share WiFi credentials with others without scanning the code.
One handed mode
This feature appeared as a hidden feature in the first developer preview of Android 12, and was not officially announced before the second developer preview. The operation of this function is very similar to the one handed mode in IOS. After the corresponding function is activated in Android settings, it can slide down at any position at the bottom of the screen, which will drive the display content to move down, so that users can better touch buttons, icons or other functions.
Vibration feedback sound effect
Google allows developers to use tactile feedback mode in Android 12 that generates vibration based on audio. In this mode, the intensity and duration of vibration are determined by the audio, which can increase the immersion when playing media or generating warnings. Google said, for example, that the video phone app can use a specific ring tone to identify the caller’s information by vibration, and simulate the touch of the ground in racing games.
Upgrading art through Google play
Android runtime (Art) will be added to project mainline in Android 12, which means that it can be updated through Google play store without a complete system upgrade. Google also pointed out that project mainline will promote more independent updates of key components of the system.
At present, Google has confirmed that at least one new widget will be installed, which is the weather widget shown above. However, there may be more new widgets.
A few weeks before the release of the developer preview, the rumored prototype of Android 12 “dialogue” widget appeared. Now it seems that the function has been integrated into Android 12 and can work normally. XDA, a well-known Android community, confirms that the widget can work normally through reverse engineering, but it is temporarily unavailable in the pixel launcher desktop. Another problem is that the widget can’t be used separately from Google suite for the time being.
Considering that the function at least exists in the current system, we are expected to see Google officially release the function in the whole life cycle of Android 12, but it is also possible that the function will be removed before the final official release of Android 12.
New widget management interface
When you want to add a widget to the home screen, you can now see more widget categories. The new design makes it easier for you to find the app you want and then add the widgets that the app has. This improvement is subtle, but it makes the widget easier to use.
Android 12 (left) vs. Android 11
Are you bored with the extra space occupied by an app that you don’t use frequently? In Android 12, the functions of APP hibernation or “rarely used app” can manage the occupation of these apps through specific rules. At present, the function has entered the Android open source project AOSP, and Google has confirmed the existence of the function.
This feature can delete the permission of unused app and clean up the temporary files and cache generated by app. Android users can use this function in the app’s information interface.
If your mobile phone has a large capacity, maybe this function is not particularly important; But for low-end machines or old devices, this would be a pretty good feature.
Other features of Android 12
App general startup screen. In order to make the app’s startup experience more unified, Android 12 has built a startup screen for each app. Even if the developer does not build the startup screen, the app will still automatically display the startup screen. Of course, developers can also adjust themselves to adapt to the design and brand of the app.
Support avif image format. As an old image compression algorithm, JPEG has been accompanied by the smart machine is too old. Android 12 introduces support for avif. This image format can provide higher image quality than JPEG without increasing volume. This format relies on AV1, the first open source video encoder introduced by Android 10.
Screen capture tag. If you use a pixel device to take a screenshot, you can use a tool like a brush to mark the screenshot. Users can add text, emoticons and stickers to the screenshots. This is not a creative design, but it can make users no longer need the corresponding third-party app.
Hide the selfie camera. Google provides the option of hiding the camera for pixel 5 mobile phone. You can turn on this setting in the developer option. The self timer camera will be hidden by the black bar, and the status bar will be integrated in the black bar at this time.
Fine tuned the settings page. Android 12 made some minor adjustments to the settings page, the search bar became smaller, and the toggle switches looked different everywhere.
Universal media transcoding. Although hevc coding is becoming more and more popular, there are still some apps that are not compatible with hevc. Now, Android 12 introduces a universal media transcoding layer, and apps that don’t support hevc can transcode to AVC through it to play Related videos smoothly.
Multi channel audio. Android 12 supports mpeg-h in both pass through and offload modes, and audio mixers, resamplers, and effectors now support up to 24 channels of audio.
Easy selection of audio source. In Android 11, the media player will be displayed in the notification center. Now Android 12 further supports long press on the player in the notification bar to go to specific settings. Users can choose whether to let the app activate the player. For example, you can control the YouTube app not to activate the player in the notification bar, but to display the player when the spotify app plays songs.
Rich text insertion. Google in the keyboard, through the clipboard and drag and drop function, provides users with more rich text insertion options. The new API allows users to insert images, video, audio, and so on from various sources.
Front desk service. In Android 12, Google will prevent the app from starting the foreground service from the background. Instead, developers can use Android 12’s job scheduler to control the app’s processing priority.
Restrict access to MAC address. In Android 11, only specific authorized apps can access the MAC address. Now, no matter what the app’s permissions are, Google restricts the app’s access to the MAC address.
Fine tuning of immersion mode. In Android 12, gesture navigation in immersion mode will become easier to use and more consistent.
System performance improvement. Google has improved the latency and workload allocation of Android 12, which will improve the performance of key processes of the system.
Optimize the large screen display. Google pays more attention to large screen devices such as tablet computers, foldable devices and TVs. Android 12 optimizes the large screen display, and the developer preview version of Android 12 will be applicable to Android TV.
Some debugging changes. Google has made some changes to make it easier for developers to debug their apps. The relevant options for these changes can be obtained from the developer options page or ADB.
The above are some of the main new features of Android 12. The improvement of this new generation of Android system is not limited to this, but is limited to space. I will not list them one by one here. According to convention, Android 12 will release its official version in September this year. Let’s look forward to it.
