CentOS 6.2 下 adb devices 出现 ???????????? no permissions 的解决

默认情况下 没有以root权限启动adb将出现以下结果

$ adb devices

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached

????????????    no permissions

百度 谷歌 一番后才得以解决

# vim /etc/udev/rules.d/50-android.rules

加入以下行

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0666"

保存

#chmod a+r /etc/udev/rules.d/50-android.rules

#adb kill-server (需要环境变量支持)

重新插入android设备
