I am using a Samsung galaxy nexus phone (Android 4.0 platform) .
I am developing Android app on Ubuntu linux OS. I would like to run my application
If anyone faces the following error message when they use adb devices
adb devices
no permissions (verify udev rules); see [http://developer.android.com/tools/device.html]
Execute the following
sudo -s adb kill-server adb start-server
That fixed the issue for me on a custom build android device
