Connecting device and running command

1. To use ADB with your Android device, you must enable a feature called USB debugging. Open your phone’s app drawer, tap the Settings icon, and select “About Phone”. Scroll all the way down and tap the “Build Number” item seven times. You should get a message saying you are now a developer.

2. Head back to the main Settings page, and you should see a new option near the bottom called “Developer Options”. Open that, and enable “USB Debugging”.

3. Later on, when you connect your phone to your computer, you’ll see a popup entitled “Allow USB Debugging?” on your phone. Check the “Always allow from this computer” box and tap OK. Select connection type to MTP from charge only if this doesn't pop up.
