Google Releases New Android 12 Developer Preview

Google has released the second developer preview for Android 12, the upcoming version of Google’s mobile operating system. The preview gives developers a sense of the new features the refreshed OS will offer and it includes updates related to security and users' experience.

The first developer beta of Android 12 was launched in February, making some unknown changes to the OS aimed at both consumers and enterprise users. Most app-facing changes will be opt-in for developers, giving them more time to ensure their apps are compatible with the new version.

"In Android 12 we’re making the OS smarter, easier to use, and better performing, with privacy and security at the core. We’re also working to give you new tools for building great experiences for users, whether they’re using phones, laptops, tablets, TVs, or cars,"  VP of Engineering Dave Burke wrote in a blog post.

"Some things to look for in today’s release include new rounded corners APIs, improved picture-in-picture APIs, better companion device management, easier effects like blur and color filter, app overlay controls, and more." 

The beta release is expected to be available as early as May, while the final release is expected sometime in August or later. Developers already running the first Android 12 preview can get an over-the-air (OTA) update.

Some highlights from this release:

App overlay controls: Developers can control whether alerts for important actions can be shown over their content in Android 12. Currently, the alert interrupts the users.

Extended security for lock screen notification actions: Developers can now configure notification actions so that when triggered from the lock screen, they generate an authentication challenge. For example, a messaging app could require authentication before a user deletes a message or marks it as read.

Support for rounded corners: Google is introducing new APIs to let developers query for rounded corners on a device, helping an app match the aesthetics of the device.

Picture in Picture (PIP) improvements: For people using gesture nav, Google has improved how apps transition to picture-in-picture (PIP) mode on swipe up-to-home. Among other changes, this means improved PIP window resizing for non-video content.

Keeping companion device apps awake: For apps that manage companion devices like smartwatches and fitness trackers, Google is extending the Companion Device Manager with a new CompanionDeviceService API. This will help ensure the app is running and connected whenever an associated companion device is nearby.
