ADB, which is the Android Debugging Bridge, is a command line tool with the Android SDK that allows you to perform multiple operations on your Andriod mobile phone.

For example, the following error occurs when you try to run adb on your Ubuntu:
./Adb devices
List of devices attached
???????????? No permissions

Fix the error with just a few lines of command (first use the cd command to switch to the android-sdk-linux_x86/platform-tools Folder ):

./Adb kill-server
Sudo./adb start-server

Now adb should be able to work:
Linuxidc@www.linuxidc.com :~ /Desktop/android-sdk-linux_x86/platform-tools $./adb devices
List of devices attached
HT0BJRX10210 device

Note: Make sure that the troubleshooting option "Settings> Applications> Development" is activated ).
