Google has launched the second Android 11 developer preview that rolled out on Friday. The preview comes with hinge angle detection support, call screening improvements and new ops in the Neural Networks API.
The preview comes nearly a month after the first preview was released. In this new release, Google will be pushing an over-the-air (OTA) update. The new preview includes a preview SDK with system images for the Pixel 2, Pixel 2 XL, Pixel 3. And Pixel 3 XL, Pixel 3a, Pixel 3a XL, Pixel 4, and Pixel 4 XL. And an additional official Android Emulator.
The second preview comes a set of features that include a 5G state API to see if a user is currently on a 5G network.
The new features give better support for foldable devices. It comes with a new API that can read data from a hinge-angle sensor so that apps can adapt to the angle of the hinge. There also are new APIs for screening robocalls and support for variable refresh rates.
For developers who use neural networks in their apps, Android 11 will include a new “hard swish-op” function that will enable faster and more accurate training for on-device models.
When an Android 11 device reboots after an overnight over-the-air update, it can now immediately access Credential Encrypted storage. It will start receiving messages right away.
Android 11 comes with a scoped storage feature that has better management of cached files and supports to move files from the legacy scoped storage model to the new model efficiently.
Whereby In current versions, the phone would mostly lie dormant. Until you logged in with your credentials.
The first preview has a focus on messaging, conversation and bubbles, better application performance and screen recording. Also has a few tweaks on automated dark mode toggles. Comes with a motion sensor gesture for pixel 4 and increased touch sensitivity.
