Mikhail Naganov 55dd33f14f Update VtsHalAudioPolicyV1_0TargetTest to match XML changes 
There was a proposal for a backward-compatible XML schema change
(https://android-review.googlesource.com/q/I1bf31c6bf6c57c9b79f0d5751601aa77780f1f80)
which had a mistake. Express the change correctly to match
the implementation.

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.
