Ubuntu: Android device debug [duplicate]

Answer 1

This is because you haven't given your adb the permission to access to your hardware. You have two solutions:

temporary -> kill all existing adb processes and restart with super user

ps -ef | grep adb | awk '{print $2}' | xargs kill

sudo adb server-restart

or

sudo /platform-tools/adb server-restart

permanent -> add your devices to udev list Add following line to your /etc/udev/rules.d/51-android.rules as root with correct idVendor using this list.

SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"

followed by following command:

chmod a+r /etc/udev/rules.d/51-android.rules

If adb doesn't work do the following:

sudo ln -s /platform-tools/adb /usr/local/sbin/adb
