Google Launches the First Developer Preview of Android 12

7 min read


Just about precisely one year since Google announced its first Android 11 developer preview, the company today launched its first Android 12 developer preview. Google postponed its implementation of Android 11 slightly even as teams, as well as partner organizations of the corporation, were adjusted to work during a pandemic, but that doesn’t seem to stop Android 12 from being kept up on schedule. As you might anticipate from a previous developer preview, many other alterations have been under hood and also for unfortunate non-developers who would like to start giving it a spin, no over-the-air updates yet.

One of the best bits of the publication to date – but it’s worth noting that Google appears to append more user-faced changes and UI updates throughout the entire preview cycle – is the ability to transcode media into higher-level formats, such as AV1 image format, quicker and much more responsive notifications as well as a new program to developers which can now switch over individual platform adjustments.

Google also guarantees that, as with Android 11, this will add a stabilization platform to Android 12 to advise creators when final app-facing changes take place in the operating system’s development process. This was the milestone that the team hit last year when its second release candidate started in July.

“We’re trying to make the OS simpler, smarter to get and best functioning with privacy and security at its core from each version,” writes Dave Burke, Google’s VP Engineering. “We are also working in Android 12 to provide you with new tools to create a good user experience. Begin with stuff like media transcoding that helps your app operate with new video formats when you wouldn’t support these formats and already make a copy and paste rich content, such as videos and pictures, simpler into your applications. We still add privacy safeguards, refresh the user productivity and interface to maintain your apps receptive.”

There are many, clearly dozens of notifications in Android 12 that look like developers. Let’s take a closer look into some.

Google will therefore be using the same SameSite cookie performance for the WebView in Android 12 as in Chrome, for instance. Last year, the firm slowed down the implementation of changes, making it more difficult for advertising agencies to track your business across Chrome websites simply as it broke too many websites. Presently, the Android squad apparently feels such as this implemented fully in Chrome, as well; it could use the same security tools on WebView that other applications use for web content display, as well.

With regard to just the encode capable functions, he says, “With the incidence of HEVC hardware encoders on smartphones, camera apps have been increasingly being recorded in HEVC format, that also offers considerable performance and compression advancements over old codecs.” For many other apps, however, Android 12 presently provides a service for transcoding files into AVCs. For all those applications that are not capable of HEVC, he reports.

Furthermore, Android 12 presently supports this same AV1 Image File Layout as a picture container as well as the GIF image sequences. “AVIF takes full advantage, like many advanced image formats, with intra-frame video compression content,” says Burke. “The picture quality of the same file size improves greatly in comparison with older image formats, like JPEG.”



Google proceeds to tinker with an alert system like with any Android release. One such time, the group guarantees an updated design that makes it “extra advanced, easier to operate and much more operational.” Burke calls for optimized transitions as well as animations and also the capacity for applications to customize customized data notifications. Google is also now requesting creators to implement a system that immediately transfers users without even a broadcast recipient or service from either a notification to the app, which it suggested earlier.

Now, Android 12 is also more effective for multi-channel audio (a bounce to music and other audio applications, no doubt), MPEG-H, Space Audio, as well as haptic-coupled audio, vibrational strength but also frequency-based sound (a boon for games, no doubt). Enhanced navigation of its gesture and numerous other improvements and slight operating system alterations are also provided.

Google is also continuing to push its Project Mainline forward, which enables an overwhelming number of core Android operating system capabilities also to be revised using Google Play — thus bypassing most hardware producers’ slow update cycles. The Android 12 module is added to the mainline by Android and can then push updates to the core execution time and libraries to devices from Google. “Without a complete system update, we could even enhance runtime performance and correctness, handle memory extra effectively and speed Kotlin operation,” says Burke. “The features of existing modules have also been expanded – for instance, we provide our seamless transcoding capabilities inside the modernizable module.”

Developers wishing to get their apps to Android 12 began by flashing a picture of the device on a pixel device today. The Pixels 3a and 3a XL, Pixels 3 and 3 XL, Pixels 4a and 4a 5G, Pixels 4 and 4 XL, and lastly, Pixels 5 are now supported by Android 12. In Google’s Android Studio, users could also use the system image throughout the Android Emulator.
