Enable USB debugging on your device

• On most devices running Android 3.2 or older, you can find the option under        Settings > Applications > Development.
• On Android 4.0 and newer, it's in Settings > Developer options.       

  Note: On Android 4.2 and newer, Developer        options is hidden by default. To make it available, go        to Settings > About phone and tap Build number        seven times. Return to the previous screen to find Developer options.

• Set up your system to detect your device.   
  • If you're developing on Windows, you need to install a USB driver for adb. For an installation guide and links to OEM drivers, see the OEM USB Drivers document.
  • If you're developing on Mac OS X, it just works. Skip this step.
  • If you're developing on Ubuntu Linux, you need to add audev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by theATTR{idVendor} property. For a list of vendor IDs, see  USB Vendor IDs, below. To set up device detection on Ubuntu Linux:       
    1. Log in as root and create this file:            /etc/udev/rules.d/android.rules.           

       Use this format to add each vendor to the file: SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", MODE="0666", GROUP="plugdev"
                  

    2. Now execute: chmod a+r /etc/udev/rules.d/android.rules

　　When plugged in over USB, you can verify that your device is connected by executing adb devices from your SDK platform-tools/ directory. If connected, you'll see the device name listed as a "device."
