To be included into ROMs to replace the AOSP Camera. Has been tested for treble ROMs with Huawei EMUI-8 vendor partition. It will only work, if the respective binaries, drivers etc. to activate the Camera deamon etc. are present.
This means: If the AOSP Camera does not work on your ROM, this one won't work either!
Add the statement PRODUCT_PACKAGES += HWCamera2 into a product.mk file (not an Android.mk file)
