What’s new about that ?
As the first version, Android 12 Developer Preview 2 won’t have many public-facing features. This remains focused on behind-the-scenes features for programmers. However, there are still a few significant improvements, including ones you’ll notice once apps and phones are updated to use the new platform.
Security and trust are strong focuses for the new release. App creators can require authentication for tasks even from the lock screen, for example. Developers can also ask Android to verify the integrity of an installed app, and prevent system overlay alerts from showing over their content.
Some other Android 12 Developer Preview 2 upgrades should lead to a slicker overall experience. New frameworks will help teams write apps for phones with rounded corners. Picture-in-picture viewing should now have smoother transitions and resizing. It’ll be easier for apps to keep smartwatches and other companion devices awake, too. Apps now have access to better bandwidth estimates, and it’ll require less effort to produce visual effects like blurs and color filters.
Maintain an eye on Android Authority in the days ahead, as it won’t be surprising if Developer Preview 2 brings other improvements to Android 12 beyond what Google has discussed so far.
When can you obtain Android 12?
Google says it’s still on track to achieve “platform stability” for Android 12 by August 2021. We wouldn’t rule out a delay for a stable given the ongoing COVID-19 pandemic, but that’s roughly in line with releases in past years.
A public beta is less certain. Google released the first beta for Android 11 on June 10th, 2020. but it won’t be surprising if the timing shifts by a few weeks if the beta is delayed or even finished early. While it’s comforting that Android 12 Developer Preview 2 is on schedule, then, it’s not a guarantee that you’ll have the new software in your hands at a certain point in time.
