Encountering the “device unauthorized” error in Android Studio can be quite frustrating, especially when you are trying to debug or test your application. This error typically suggests that your device is not correctly authorized for USB debugging with your development machine. This guide will walk you through the steps to resolve this issue efficiently.
Understanding the Issue
The error message “device unauthorized” often appears when the Android Debug Bridge (ADB) is unable to establish a trusted connection with your device. This can happen due to a variety of reasons such as missing authorization, incorrect USB connection mode, or even hardware issues like a faulty USB cable.
Step-by-Step Solutions
1. Revoke USB Debugging Authorization
- Navigate to Settings on your Android device.
- Open Developer Options.
- Select Revoke USB Debugging Authorizations.
- Disconnect your device from the computer.
- Reconnect your device and watch for the fingerprint authorization dialog. Ensure you accept it.
2. Reset ADB Server
- Open a terminal or command prompt.
- Execute the following commands:
adb kill-server adb start-server
- Reconnect your device and verify the authorization dialog appears.
3. Check USB Connection Mode
- Change the USB connection mode on your device to Media Transfer Protocol (MTP) or another mode, and then revert to Charging only.
- Reconnect your device and accept the authorization request.
4. Inspect USB Hardware
- Ensure that your USB cable is functioning correctly. Consider using a different cable if issues persist.
- Try connecting to a different USB port on your computer.
Additional Tips
Sometimes, simply restarting your device or the development machine can also help in resolving connectivity issues. Make sure your Android Studio and SDK tools are updated to the latest versions to avoid compatibility problems.
