本文主要是介绍Android10.0(Q) HAL层 light2.0 改动记录及排错过程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

LightsService 灯光服务提供了LCD背光灯、键盘灯、按键灯、警示灯、电池灯、

消息通知灯、蓝牙灯、wifi灯等八种类型灯光；都是基于 android.hardware.light.V2_0.Type

现有需求需要新增第九中类型灯光控制，找到定义 Type 的地方

hardware\interfaces\light\2.0\types.hal

/*** These light IDs correspond to logical lights, not physical.* So for example, if your INDICATOR light is in line with your* BUTTONS, it might make sense to also light the INDICATOR* light to a reasonable color when the BUTTONS are lit.*/
enum Type : int32_t {BACKLIGHT,KEYBOARD,BUTTONS,BATTERY,NOTIFICATIONS,ATTENTION,BLUETOOTH,WIFI,FLASH_TRIG,COUNT,
};

hardware\interfaces\light\2.0\default\Light.cpp

const static std::map<Type, const char*> kLogicalLights = {{Type::BACKLIGHT,     LIGHT_ID_BACKLIGHT},{Type::KEYBOARD,      LIGHT_ID_KEYBOARD},{Type::BUTTONS,       LIGHT_ID_BUTTONS},{Type::BATTERY,       LIGHT_ID_BATTERY},{Type::NOTIFICATIONS, LIGHT_ID_NOTIFICATIONS},{Type::ATTENTION,     LIGHT_ID_ATTENTION},{Type::BLUETOOTH,     LIGHT_ID_BLUETOOTH},{Type::WIFI,          LIGHT_ID_WIFI},{Type::FLASH_TRIG,    LIGHT_ID_FLASH_TRIG}
};

frameworks\base\services\core\java\com\android\server\lights\LightsManager.java


package com.android.server.lights;import android.hardware.light.V2_0.Type;public abstract class LightsManager {public static final int LIGHT_ID_BACKLIGHT = Type.BACKLIGHT;public static final int LIGHT_ID_KEYBOARD = Type.KEYBOARD;public static final int LIGHT_ID_BUTTONS = Type.BUTTONS;public static final int LIGHT_ID_BATTERY = Type.BATTERY;public static final int LIGHT_ID_NOTIFICATIONS = Type.NOTIFICATIONS;public static final int LIGHT_ID_ATTENTION = Type.ATTENTION;public static final int LIGHT_ID_BLUETOOTH = Type.BLUETOOTH;public static final int LIGHT_ID_WIFI = Type.WIFI;public static final int LIGHT_ID_FLASH_TRIG = Type.FLASH_TRIG;public static final int LIGHT_ID_COUNT = Type.COUNT;public abstract Light getLight(int id);
}

修改如上几个地方后，编译报错

错误一、which does not match hash on record. This interface has been frozen. Do not change it!

ERROR: output handler failed.

ERROR: android.hardware.light@2.0::types has hash cd082c47c3940f2c4d4ef489c9f34e0c737dfcbd7dd09e0e270563e699a9d91e which does not match hash on record. This interface has been frozen. Do not change it!
ERROR: Could not parse android.hardware.light@2.0::types. Aborting.

原因：Android P 开始，Google 对 Hidl 有了严格的限制。Google release 出来的 hidl 接口不允许修改。

需要重新生成修改 hardware 对应的 hashcode,错误中已经包含新的 hashcode 值 cd082c47c3940f2c4d4ef489c9f34e0c737dfcbd7dd09e0e270563e699a9d91e

如果没有此 hashcode 值，可以通过指令 hidl-gen -L hash -r 来生成,得到和错误提示中的hash值一模一样

$ hidl-gen -L hash -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.light@2.0::types
cd082c47c3940f2c4d4ef489c9f34e0c737dfcbd7dd09e0e270563e699a9d91e android.hardware.light@2.0::types

将刚刚得到的新 hashcode 值更新到 hardware/interfaces/current.txt

可直接在文档末尾增加 cd082c47c3940f2c4d4ef489c9f34e0c737dfcbd7dd09e0e270563e699a9d91e android.hardware.light@2.0::types

看到 making libs for product: aosp_arm_ab 这行，这个是因为我的项目 product名字不一样导致的，加上参数-product product_name 即可，product_name 是你的项目的 product 名称。
