What is HIDL?

HIDL (HAL Interface Definition Language) is an interface definition language used in Android, specifically from Android 8.0 (Oreo) onwards. It's designed to define the interface between the Android framework and the hardware-specific implementations (HALs). HIDL enables independent development of Android and vendor hardware by defining a stable ABI/API that does not require recompilation when either side is updated. It essentially serializes calls between the framework and HAL into a standardized format.
