场景
手机环境比较特殊，需要长期充电，无法使用USB口进行调试，需要重启手机之后，自动进入WIFI调试
修改mIsAdbUsbEnabled为1
路径：frameworks/base/services/core/java/com/android/server/adb/AdbService.java
主要查看左侧角标判断是否需要删除新增

修改device设备配置文件
路径-1：device/google/coral/device-coral.mk
路径-2：device/google/coral/device-flame.mk
这两个文本文件下，添加以下内容到文件最底部，同时两个文件都要加
persist.adb.tls_server.enable=1
修改AdbDebuggingManger.java
主要是屏蔽相关的判断规则，实现断开wifi或者关闭wifi都保留调试状态，可能就是比较耗电一些。

修改完之后，就可以开始编译，查看是否生效了。
