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
).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

default

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.
