How to Use Android Debug Bridge (ADB) for Advanced Device Management

Introduction

Android Debug Bridge (ADB) is a versatile command-line tool that enables users to communicate with and control Android devices from a computer. ADB is widely used by developers, tech enthusiasts, and IT professionals to perform advanced device management tasks such as debugging, installing applications, transferring files, and even unlocking hidden features. This guide will walk you through the fundamentals of ADB, its advanced features, and how you can leverage it for effective device management.

What is ADB?
