Launched in September 2020, Android 11 is the latest stable version of Google’s Android operating system. And the company is expected to release the 12th major generation of Android, Android 12 in August/September this year.
Ahead of the stable release, Google also pushed the first Android 12 developer preview back in February 2021. This activity lets developers (only Google Pixel users) understand and grow the Android 12 ecosystem.
Now, according to the information, Google released the Android 12 Developer Preview 2 which moves the Samsung Galaxy users one step closer to the next generation of One UI – One UI 4.0. This update brings plenty of new features as well as major system optimizations.
However, Samsung’s self-developed user interface is also based on Google’s Android OS. And as per the naming strategy, the Korean tech giant will develop the next version of One UI, the One UI 4.0 based on Android 12.
Coming back, interested Pixel smartphone users can now manually download and check the release timeline of the Android 12 by going through the developer site. Besides, we’re mentioning the newly added features and revisions from the official webpage that come with the Android 12 Developer Preview 2.
Android 12 Developer Preview 2:
Picture in Picture (PIP) improvements:
In this multitasking world, the picture-in-picture function is a feature that users need to access easily. Google is using the latest version to improve its PIP model.
Now, the function of converting the application to the picture-in-picture (PIP) mode at home has been improved. If an application has automatic PIP enabled, the system can now convert it to PIP mode directly in the home without waiting for the home animation to complete.
Easier blurs, color filters, and other effects:
Google is making it easier to apply common graphics effects to your Views and rendering hierarchies in the Android 12. Users can use RenderEffect to apply blurs, color filters, and more to any RenderNode.
Extended security for lock screen notification actions:
The Developer Preview 2 of Android 12 comes with added security to the controls over the notifications displayed on the lock screen. You will be able to configure the notification actions, so when these are accessed from the notifications it will show authentication besides revealing it. This extends the notification visibility controls already available through the notification APIs.
Support for Rounded corners:
Following the trend, Google has also added rounded corner functionality on the screen to provide a clean and modern look. In order to deliver a great user experience, developers need to account for the rounded corners and adjust any nearby UI elements to prevent them from being truncated.
App overlay controls:
Google has added another new function in the Android 12 that will now provide controls for whether these app overlays need to be shown on the top of the active app. Android’s system alert window gives apps a way to get user’s attention for important actions by showing then overlay on the top of the active app which can interrupt the users.
Access to app digests:
For applications that need to verify the integrity of application packages installed on Android devices, we have introduced a new API that allows you to query the checksum of installed applications directly on the platform. You can choose from several digest algorithms, such as SHA256, SHA512, Merkle Root, etc.
Bandwidth estimation improvements:
Android 12 will provide users with improved bandwidth estimation to provide a better service experience. The bandwidth estimation function has been enhanced to enable users to retrieve total throughput estimates for each carrier or Wi-Fi SSID, network type, and the signal level of all users on the device.
Keeping companion device apps awake:
Companion devices that need to be managed by smartphones (such as smartwatches and fitness trackers) have also received some new and easy-to-use information.
Google is using the new CompanionDeviceService API to extend CompanionDevice Manager. The application that manages the companion device can implement this service so that the system can wake up the application when the companion device is nearby.
