Android 17 Beta 4 is now rolling out to Pixel devices, and Google says it is the “last scheduled beta of this release cycle.” After the larger Beta 3 update brought new features and platform stability, this release appears focused on final refinements ahead of a stable launch later this quarter.
To install Android 17 Beta 4, Pixel users can enroll through the Android Beta program and wait for the over-the-air update. Those who prefer the manual route can also flash a factory image or OTA file.
The latest build details are below:
Release date: April 16, 2026
Build: CP21.260330.008
Emulator support: x86 (64-bit), ARM (v8-A)
Security patch level: 2026-04-05
Google Play services: 26.11.36
Android 17 Beta 4 supports Pixel devices back to the Pixel 6 lineup.
Developer changes
One of the main additions in Android 17 Beta 4 is conservative app memory limits, which are meant to improve system stability. If an app is killed because of these limits, ApplicationExitInfo.getDescription will return “MemoryLimiter.” Developers can also use trigger-based profiling with TRIGGER_TYPE_ANOMALY to capture heap dumps when the limits are reached.
Google has also tightened background audio rules. Starting in Android 17, the audio framework restricts background interactions such as audio playback, audio focus requests, and volume change APIs. Some changes were made after feedback from beta 2, including targetSDK gating for while-in-use FGS enforcement and exemptions for alarm audio.
