Kuowei Li de829572f9 audio: Allow SetAudioProperties to not be supported 
The parameter of sample rate, channel mask and format is not
mandatory to support by Audio HAL. At meantime, there is no
corresponding handle in framework.
Hence, SetAudioProperties should allow reporting not supported.

Bug: 194368657

Test: run vts -m VtsHalAudioV7_0Target

Audio HAL

Directory structure of the audio HAL related code.

Run common/all-versions/copyHAL.sh to create a new version of the audio HAL based on an existing one.

Directory Structure

  • 2.0 — version 2.0 of the core HIDL API. Note that .hal files can not be moved into the core directory because that would change its namespace and include path.
    • config — the XSD schema for the Audio Policy Manager configuration file.
  • 4.0 — version 4.0 of the core HIDL API.
  • ...
  • common — common types for audio core and effect HIDL API.
    • 2.0 — version 2.0 of the common types HIDL API.
    • 4.0 — version 4.0.
    • ...
    • 7.0 — version 7.0.
      • example — example implementation of the core and effect V7.0 API. It represents a "fake" audio HAL that doesn't actually communicate with hardware.
    • all-versions — code common to all version of both core and effect API.
      • default — shared code of the default implementation.
        • service — vendor HAL service for hosting the default implementation.
      • test — utilities used by tests.
      • util — utilities used by both implementation and tests.
  • core — VTS tests and the default implementation of the core API (not HIDL API, it's in audio/N.M).
    • 7.0 — code specific to version V7.0 of the core HIDL API
    • all-versions — the code is common between all versions, version-specific parts are enclosed into conditional directives of preprocessor or reside in dedicated files.
      • default — code that wraps the legacy API (from hardware/libhardware).
        • util — utilities for the default implementation.
      • vts VTS tests for the core HIDL API.
  • effect — same for the effect HIDL API.
    • 2.0
      • config — the XSD schema for the Audio Effects configuration file.
    • 4.0
    • ...
    • all-versions
      • default — code that wraps the legacy API (from hardware/libhardware).
        • util — utilities for the default implementation.
      • vts VTS tests for the effect HIDL API.
  • policy — Configurable Audio Policy schemes.
    • 1.0 — note that versions of CAP are not linked to the versions of audio HAL.
      • vts — VTS tests for validating actual configuration files.
      • xml — XSD schemas for CAP configuration files.
