虚拟中安装adb后，使用adb devices，能看到id，但提示用户无权限

$ adb devices
List of devices attached
1c22d6dc no permissions (user in plugdev group; are your udev rules wrong?); see [http://developer.android.com/tools/device.html]

$ adb shell
error: insufficient permissions for device: user in plugdev group; are your udev rules wrong?
See [http://developer.android.com/tools/device.html] for more information

 

解决办法：

1、在下面路径创建规则文件

sudo gedit /etc/udev/rules.d/xxx.rules

2、规则文件中输入以下内容

SUBSYSTEM=="usb", MODE="0660", GROUP="plugdev", SYMLINK+="android%n"

 3、再次拔插手机即可
