Introduction to ADB and ADB Shell
ADB (Android Debug Bridge) is a multi-purpose command-line tool that allows you to communicate with an Android device. Through it, you can perform various tasks on the device. For example, you can retrieve device status information, install or uninstall apps, control the device, extract logs, or transfer files.
ADB Shell is a feature of ADB that allows you to access the Linux command line of an Android device. Through it, you can explore the device's file system, manage system and app processes, or change system settings.
ADB connects your PC and Android device via USB or Wi-Fi, and through this connection, you can perform various tasks. For example, you can install or uninstall apps, control the device, extract logs, or transfer files.
