Android 8.1 默认打开“无线ADB调试”

网络adb生效的地方：
out/target/product/rk3288/root/init.rk30board.rc

# for Internet adb
on property:persist.internet.adb.enable=1
    setprop service.adb.tcp.port 5555
    restart adbd

# for Internet adb
on property:persist.internet.adb.enable=0
    setprop service.adb.tcp.port 0
    restart adbd

service.adb.tcp.port 5555表示网络无线adb

那么修改的地方就是在device .mk文件中增加：

persist.internet.adb.enable=1
