Audio HAL V5: Introduce HAL V5, equal to V4 for now
find -name 4.0 | xargs -I@ cp -r @ @/../5.0
find 5.0 */5.0 -type f | xargs sed -Ei 's/V4/V5/;s#(@|/)4.0#\15.0#'
find -name *cpp -o -name *.h | xargs sed -i 's/VERSION == 4/VERSION >= 4/g'
mv {4.1,5.0}/config/audio_policy_configuration.xsd
Then a manual update to Android.bp to add V5 support.
Then a manual update to service.cpp to add support for loading 5.0.
If someone knows a way to avoid copying the .hal, it would be great.
They will be 99% identical between V4 and V5.
