set up device for development (???????????? no permissions)

Question

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

Answer 1

In Archlinux this can happen occasionally. The fix:

$ sudo -s
# adb kill-server
# adb start-server

Answer 2

My device is POSITIVO and my operational system is Ubuntu 14.04 LTS So, my problem was in variable name

I create the file /etc/udev/rules.d/51-android.rules and put SUBSYSTEM=="usb", SYSFS{idVendor}=="1662", MODE="0666"

I disconnected device and execute:

$ sudo udevadm control --reload-rules
$ sudo service udev restart

after this i connected the android device in developer mode again and

$ adb devices
