Google is pleased to share this Android 25Q2 release with Android Automotive partners. For Android 16, this Android Automotive 25Q2 release is compliant. We continue to fine tune features, aiming to recommend an upcoming release for OEMs.
Release details
This section summarizes major features and enhancements provided in the AAOS B release.
These updates apply to Android16, API level 36.
The Android Automotive 25Q2 release is compliant with Android 16.
New features
The 25Q2 release provides these new features.
AAOS Framework
Audio and radio:
Audio control HAL improvements: To configure car audio features, use APIs instead of XML file.
High definition (HD) radio Emergency Alert System (EAS): Pass EAS information to radio applications with an API. This applies to HD Radio (North America) and DAB EWS (European Union).
AAudio built-in library: AAudio AAudio supports OEM-defined Audio Attributes tags to customize app behavior. For example, audio routing and volume management.
Power management:
- Power state notifications to built-in processes: The availability of power state notifications to OEM built-in processes (beyond Android apps) is extended.
Car framework:
- Dynamic configuration of vehicle properties: Support the dynamic configuration of minimum and maximum and of supported values in vehicle properties.
Connectivity
Networking:
Minimal Telephony: A subset of the Android Telephony Hardware Abstraction Layer (HAL) for automotive OEMs to allow OEMs to use Android telephony on data-only devices (including TCUs). This reduces fragmentation and provides support for telephony functionality.
Connectivity Messaging Upsell API: Enhanced SubscriptionManager to provide APIs that can expose a user's mobile data subscription status. For example,
active,inactive,trial, and expiration date.Projected app support: Added support to let automotive OEMs configure the complete set of
hostapd.confparameters not available through the Android APIs. Added a disconnect reason to the SoftApCallback API so that OEMs can learn why clients disconnected from a Local Hotspot (LOHS). These features improve support for projected apps and reduce fragmentation.
AAOS System UI & Experiences
- ScalableUI: This AAOS windowing framework provides OEMs with configurable components that let OEMs meet windowing requirements and facilitate custom experiences.
VHAL properties
Vehicle properties:
Added new vehicle properties to communicate vehicle characteristics and state.
Updated vehicle property constants from @SystemApi to public APIs to consolidate generated documentation at VehiclePropertyIDs. Any previously defined and documented permissions are still required to access vehicle property data.
Third party-accessible vehicle properties: This features makes eight existing vehicle properties relevant to navigation, voice assistant, weather, and driving state available to third party app developers. To learn more, see Integrate with Google apps and services.
Compliance
Android Compliance was executed on the internal reference hardware. The test suites run for this release include CTS, CTS-V, ATS, STS, VTS and CTS on GSI.
Other than the issues listed below, there are no known failures that require a
fix either in Android 16 code (android16-release) or to the Android 16 test
branch (android16-tests-dev).
