I'm unable to detect android device using:-
adb devices
Output:-
List of devices attached
3536f11e no permissions (verify udev rules); see [http://developer.android.com/tools/device.html]
It keeps saying, no permissions.
First Kill the existing running instace of adb server by:-
adb kill-server
Then, run the adb devices
command with sudo
as :-
sudo adb devices
This will start the adb daemon and list your android device without permission error.
