Scroll all the way down and tap the “Build Number” item seven times. Open your phone’s app drawer, tap the Settings icon, and select “About Phone”. To use ADB with your Android device, you must enable a feature called USB debugging. Step Two: Enable USB Debugging on Your Phone When it’s finished, you can close the SDK manager. This downloads and installs the platform-tools package, which contains ADB and other utilities. If you are using a Nexus phone, you may also want to select “Google USB Driver” to download Google’s drivers. Start the SDK Manager EXE and deselect everything except “Android SDK Platform-tools”. Download the ZIP file for your platform and unzip it wherever you want to store the ADB files–they’re portable, so you can put them anywhere you want. Head to the Android SDK download page and scroll down to “SDK Tools Only”, which is a set of tools that includes ADB.
