The adb devices command in 2025 remains the primary way to list all Android devices connected to your development machine via USB or Wi-Fi debugging. It shows device serial numbers and their states (e.g., device, offline) to confirm connectivity and readiness for debugging or file transfer.
Key points about adb devices usage and setup in 2025:
-
Setup: You need the Android SDK Platform-Tools installed, which includes
adb. Enable USB Debugging on your Android device under Developer Options and connect via USB or set up wireless debugging [2] [3]. -
Functionality: Running
adb devicesstarts (or connects to) the adb server if not already running, which listens on TCP port 5037. It then lists attached devices or emulators with their connection status [1]. -
Common issues: Users sometimes see "offline" emulators or devices, or the adb server shutting down automatically. Restarting the server with
adb kill-serverandadb start-serveroften helps. Such issues have been reported and discussed even in 2025 Android Studio versions [5]. -
Wireless debugging: You can set up ADB over Wi-Fi by first connecting via USB, running
adb tcpip 5555, then connecting using your device’s IP address. This avoids USB cable dependency while maintaining full adb functionality [7].
Overall, adb devices in 2025 continues to be an essential command for Android development, allowing you to list connected devices or emulators for deployment, debugging, or testing, with a mostly stable toolset and updated workflow for wireless usage [2] [7]. If you encounter errors or many "offline" devices, restarting the adb server or updating platform-tools usually resolves the problem [5].
