Question regarding hidl implementation

[androidid]

Hi,

I am implementing hidl for one of the AOSP components and have a question regarding it. I have different versions of HAL that are provided by the aos/hardware/interfaces/component/ starting from 1.1, 2.0 and 2.1.

As a OEM i am working on AOSP-11 and do i need to provide implementation for all the versions (1.1, 2.0 and 2.1) or providing it for latest version (2.1) would be good enough ?

Can some one help me with this query and/ or point me the google documentation on the same please.

Thanks in advance.

Regards

Girish

hi girish,

it is up to you what version you implement.it depends what are all the interfaces you support, but you have to  implement any one of the versions.

you should point it in your manifest file what hal version is supported, so that AOSP will know to use.
