ADB (Android Debug Bridge) commands are vital for Android developers and testers, allowing interaction with Android devices for debugging and monitoring applications. Key commands include 'adb install' for installing applications, 'adb logcat' for viewing log messages, and 'adb push' to copy files to the device. With the rise of mobile app development, a solid grasp of ADB commands can streamline development processes and enhance device management capabilities. Many developers recommend regularly updating knowledge on available commands to maximize productivity in app testing and debugging.
