ADB devices : no permissions
ADB stands for Android Debug Bridge. It comes with the android sdk. Basically it is a utility that allows you to execute some really useful commands on your android device from you computer. You can extract system files from your phone, the android application files (.apk), can reboot the phone by just issuing a command, can go into both download and recovery modes and what not. Its amazing.
adb devices is the command for getting the list of android devices connected to the pc.
Anyways, just yesterday. I plugged in my samsung captivate into the usb, fired up a terminal and executed “adb devices” to make sure that my captivate is properly connected. To my surprise, it threw on me “???????????? no permissions“
shank@shank-G60VX:~$ adb devices
List of devices attached ???????????? no permissions
The reason for this problem is that when the server that runs on our pc for android devices starts, it starts without super user permissions (without root).
The solution is to execute the following in terminal:
adb kill-server
and then
sudo adb start-server
now
adb-devices
will work properly.
