Android 12 is a long way off, but developer examples give us an idea of what to expect. The developer̵
To be clear, this is still an example of a developer. So the average person probably shouldn’t download and install Android 12 on their phone just yet. But if you want to get an early look at what’s to come or make sure your apps are compatible, the second version of the Developer Preview is here.
This time, Android focuses on performance, privacy and security features. To take care of the latter, developers have new options with lock screen notifications. Developers can now configure notification actions to always activate authentication. So if your text messaging program requires authentication before a user can delete a message from the lock screen, now you can.
Round screens will also receive better support. More and more Android devices are dropping angular displays in favor of a rounded look. But that can lead to UI issues where notifications or a hamburger menu are cut off. Android 12 now has new APIs to call to give an app all the details about a phone’s angle and adjust accordingly.
Picture-in-Picture mode also has some improvements, especially for gesture navigation users. If your app has auto-pip mode enabled, an app will be automatically moved to pip mode by swiping up to go home. Apps can now automatically resize themselves as needed in pip mode, which should help avoid blocking essential items.
And with the latest preview of Android 12, smartwatches are getting better support. Smartwatches usually require a companion app to work with the watch. But when the app goes to sleep, the whole system breaks down. The developer second preview allows developers to mark an app as a companion app to stay awake when a smartwatch is nearby and connected.
You can download the developer preview of Android 12 from the developer site today.
