I recently ran into a frustrating issue while developing Android apps on the go: I wanted to test on my physical device, but wireless debugging wouldn't work over public free Wi-Fi. That's when I found this article and solved the problem. Here's my share of the method:

1. Verify adb is in your PATH

where adb

2. Add adb to PATH (if not found)

On Windows: Go to System Information → System Details → Environment Variables, then add this to your PATH and restart your terminal:

C:\Users\{YourUsername}\AppData\Local\Android\sdk\platform-tools

3. Enable PC's Mobile Hotspot

Turn on the hotspot feature on your PC (one-click on Windows 11).

4. Connect Your Android Phone to the Hotspot

Connect your phone to your PC's hotspot network.

5. Pair with adb

1. Navigate on your device: Settings → System → Developer Options → Wireless Debugging
2. Enable "Use wireless debugging"
3. Tap "Pair device with pairing code"
4. Run this command with the code that appears:

$ adb pair <IP_address:port_number>
Enter pair code: <your_pair_code>

6. Connect with adb

Your pairing is complete, but you're not connected yet. Use the IP address and port shown in your device's Wireless Debugging screen:

adb connect <IP_address:port>

Once paired, you can connect in the future using just adb connect without re-pairing. Your Android Studio should now show your device as connected!

This works on Mac and Linux too—now you can develop anywhere on the go.
