HAL 인터페이스 설명 언어 (HIDL)는 HAL과 사용자 간의 인터페이스를 지정합니다. 인터페이스 및 패키지로 수집되는 유형 및 메서드 호출을 정의합니다. HIDL은 독립적으로 컴파일될 수 있는 코드베이스 간의 통신을 위한 시스템으로, 프로세스 간 통신을 위해 설계되었습니다. HIDL 가이드를 참고하세요.
HIDL (.hal) 파일의 자동 생성된 문서가 지원 중단되었습니다.
인터페이스 사양에 관한 자세한 내용은 AOSP의 HIDL 소스 파일을 참고하세요.
HIDL 인터페이스 파일은 AOSP의 네 가지 위치에 있습니다.
- /hardware/interfaces
- /frameworks/hardware/interfaces
- /system/hardware/interfaces
- /system/libhidl/transport
각 위치의 HIDL 소스 파일 링크는 아래 섹션을 참고하세요.
/hardware/interfaces
/frameworks/hardware/interfaces
/system/hardware/interfaces
/system/libhidl/transport

It defines types and method calls, collected into interfaces and packages. HIDL is a system for communicating between codebases that may be compiled independently and is intended for inter-process communication. See the HIDL guides.\n\nThe autogenerated documentation for the HIDL (.hal) files have been deprecated.\nFor the details of the interface specifications, consult the HIDL source files\nin AOSP.\n\nHIDL interface files are in four different locations in AOSP:\n\n- /hardware/interfaces\n- /frameworks/hardware/interfaces\n- /system/hardware/interfaces\n- /system/libhidl/transport\n\nSee the sections below for links to the HIDL source files in each location.\n\n/hardware/interfaces\n--------------------\n\n- [/hardware/interfaces/](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release)\n -
