自 2025 年 3 月 27 日起,我們建議您使用 android-latest-release
而非 aosp-main
建構及貢獻 AOSP。詳情請參閱「Android 開放原始碼計畫變更」。
HIDL 介面的說明文件
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
HAL 介面描述語言 (HIDL) 可指定 HAL 與其使用者之間的介面。定義類型和方法呼叫,並收集至介面和套件。HIDL 是一種系統,可用於在可獨立編譯的程式碼集之間進行通訊,並用於處理序間通訊。請參閱 HIDL 指南。
HIDL (.hal) 檔案的系統產生說明文件已淘汰。如需介面規格的詳細資料,請參閱 AOSP 中的 HIDL 原始檔。
HIDL 介面檔案位於 AOSP 的四個不同位置:
- /hardware/interfaces
- /frameworks/hardware/interfaces
- /system/hardware/interfaces
- /system/libhidl/transport
請參閱以下各節,取得各個位置的 HIDL 來源檔案連結。
/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 -
