adb devices：no permissions或者检测不到Android真机

系统：ubuntu 16.04 LTS

adb devices

List of devices attached
xxxxxxxxxxxx no permissions

反馈信息：无权限或者检测不到Android真机

插拔两种情况下，都输入lsusb命令

列表中多出来的那一项即为当前连接的那个手机，记住它的ID xxxx1:xxxx2

sudo vim  /etc/udev/rules.d/51-android.rules

        追加一行：UBSYSTEM=="usb",ATTRS{idVendor}=="xxx1",ATTRS{idProduct}=="xxx2",MODE="0666"
 

source /etc/udev/rules.d/51-android.rules
sudo chmod a+rx /etc/udev/rules.d/51-android.rules
sudo adb kill-server
sudo adb start-server
adb devices

反馈正常
