The major change in V7.0 is use of enum values defined in the Audio Policy Configuration XSD schema. This allows decoupling types used at the HIDL layer from system/audio.h. Added a header audio_policy_configuration_V7_0-enums.h with utility functions analogous to ones from system/audio.h but defined for the types generated from XSD schema. Since the code of VTS tests is shared between versions, ensured that the VTS tests for the previous HAL versions didn't regress.

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 thecore
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 inaudio/N.M
).7.0
-- code specific to version V7.0 of the core HIDL APIall-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 (fromhardware/libhardware
).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.
