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.
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 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 (from hardware/libhardware).vts VTS tests for the core HIDL API.effect -- same for the effect HIDL API.2.0config -- the XSD schema for the Audio Effects configuration file.4.0all-versionsdefaultvtspolicy -- 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.
