What’s New in Android 11 Developer Preview? Key Features Explained
Google’s surprise early release of the Android 11 Developer Preview brings Pixel‑only support, a detailed rollout schedule, and six major enhancements—including 5G‑ready connectivity, native cut‑out and waterfall screen APIs, chat bubbles, upgraded privacy controls, screen recording, and Pixel 4 motion‑sense gestures.
Google unexpectedly released the Android 11 Developer Preview early, currently limited to Google Pixel devices (Pixel 4/4XL, 3a/3a XL, 3/3 XL, 2/2 XL) and developers.
The Android 11 development timeline shows a beta release in May and a final version slated for Q3 2020.
1. Connectivity
Android 11 introduces a new connectivity API designed for 5G networks, allowing apps to automatically switch to higher‑quality video streams when a high‑speed network is detected.
A bandwidth estimator API lets developers easily determine available downstream and upstream bandwidth without implementing custom calculations.
2. Support for New Screens
The OS now natively supports cut‑out (notch) and waterfall displays, providing APIs that let apps either avoid the notch area or fully utilize the curved edge of waterfall screens without manufacturer‑specific workarounds.
3. Floating Chat Bubbles
With a new API, apps can present ongoing conversations as floating bubbles that remain on screen, similar to the chat‑head feature.
4. Privacy and Permissions
Android 11 adds one‑time permissions for location, microphone, and camera, meaning apps must request permission again each time they need access.
The system also automatically blocks repeated permission prompts after two denials, though users can manually adjust settings.
5. Screen Recording
Screen recording, removed in early Android 10 builds, returns in Android 11, allowing users to capture on‑screen activity directly.
6. Pixel 4 Series Changes
Pixel 4 devices receive a new Motion Sense gesture that lets users pause music with a hand wave.
