自 2025 年 3 月 27 日起,我们建议您使用 android-latest-release
而非 aosp-main
构建 AOSP 并为其做出贡献。如需了解详情,请参阅 AOSP 的变更。
HIDL 接口文档
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
HAL 接口描述语言 (HIDL) 用于指定 HAL 与其用户之间的接口。它定义了类型和方法调用,这些内容会汇集到接口和软件包中。HIDL 是用于在可以独立编译的代码库之间进行通信的系统,适用于进程间通信。请参阅 HIDL 指南。
HIDL (.hal) 文件的自动生成文档已废弃。
如需详细了解接口规范,请参阅 AOSP 中的 HIDL 源文件。
HIDL 接口文件位于 AOSP 中的四个不同位置:
- /hardware/interfaces
- /frameworks/hardware/interfaces
- /system/hardware/interfaces
- /system/libhidl/transport
如需查看每个位置的 HIDL 源文件的链接,请参阅下文。
/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 -
