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.
