前言
提示：这里可以添加本文要记录的大概内容：
例如：记录Android驱动层和系统层做键值上报广播功能，kl文件是驱动和系统层的桥梁，kl文件写的内容是驱动文件设好的键值，后面的名字需要给系统层使用。
一、framework层如何配合驱动层做键值映射
示例：如何把上报流程从kl文件传到应用层，kl文件反应的是驱动上报的键值，后面的命名则是系统层读取的键值（如果已经有调试好广播名，也可以直接改为那个广播名，那么只要按下按键就会触发广播）下面是整理的补丁，系统定义的键值和kl文件里面的不需要一样，只需要保证名字是一样的，如KEYCODE_XX（kl中定义的宏）

Android中如果在framework中有修改过内容，如：current.txt需要使用make update-api来更新，否则编译会报错
二、如何查看应用层的键值广播
1.问题分析
已经从kl文件改到键值，键值能上报（中断OK）但是没有响应的动作，一改成旧的键值就可以：
一是可能kl文件映射驱动有问题
二是做完了上报流程但是最后广播那里apk接收不到（可以cat vendor/etc/scanner_config.xml看看广播是哪些，自己添加的广播app识别不到没用），所以可以替换kl文件先做试验，还可以找app查看键值上报的名字是哪个
2.方法
修改kl文件看看是不是驱动映射出了问题，要么看看是不是广播看看扫码用的apk没有识别到
如何做kl重新挂载：
dumpsys input //看kl文件位置，
adb pull xx/Generic.kl //看看里面是什么然后可以做修改，能直接验证不用重新编译版本
/*remount要解锁，所以先解锁*/
adb reboot bootloader ， fastboot flashing unlock ， fastboot reboot ，adb root ， adb disable-verity ，adb reboot
adb root ， adb remount ， adb push xx/Generic.kl （改好后的），然后再reboot
