Kể từ ngày 27 tháng 3 năm 2025, bạn nên sử dụng android-latest-release thay vì aosp-main để xây dựng và đóng góp cho AOSP. Để biết thêm thông tin, hãy xem phần Thay đổi đối với AOSP.
Tài liệu về giao diện HIDL
Sử dụng bộ sưu tập để sắp xếp ngăn nắp các trang
Lưu và phân loại nội dung dựa trên lựa chọn ưu tiên của bạn.
Ngôn ngữ mô tả giao diện HAL (HIDL) chỉ định giao diện giữa HAL và người dùng. Tệp này xác định các loại và lệnh gọi phương thức, được thu thập vào các giao diện và gói. HIDL là một hệ thống giao tiếp giữa các cơ sở mã có thể được biên dịch độc lập và dành cho giao tiếp liên quy trình. Xem hướng dẫn về HIDL.
Tài liệu được tạo tự động cho các tệp HIDL (.hal) không còn được dùng nữa.
Để biết thông tin chi tiết về thông số kỹ thuật của giao diện, hãy tham khảo các tệp nguồn HIDL trong AOSP.
Các tệp giao diện HIDL nằm ở 4 vị trí khác nhau trong AOSP:
- /hardware/interfaces
- /frameworks/hardware/interfaces
- /system/hardware/interfaces
- /system/libhidl/transport
Hãy xem các phần bên dưới để biết đường liên kết đến tệp nguồn HIDL ở mỗi vị trí.
/hardware/interfaces
/frameworks/hardware/interfaces
/system/hardware/interfaces
/system/libhidl/transport
Nội dung và mã mẫu trên trang này phải tuân thủ các giấy phép như mô tả trong phần Giấy phép nội dung. Java và OpenJDK là nhãn hiệu hoặc nhãn hiệu đã đăng ký của Oracle và/hoặc đơn vị liên kết của Oracle.

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 -
