Troubleshooting Device Detection Issues on macOS for Android Development

Troubleshooting Device Detection Issues on macOS for Android Development

30 November 2024 Stephan Petzl Leave a comment Tech-Help

Developing Android applications on macOS can sometimes present challenges, especially when a device fails to appear in the list of connected devices during debugging. This guide provides a step-by-step solution to resolve such issues, ensuring seamless connectivity between your Android device and macOS machine.

Common Causes and Solutions

Before diving into specific solutions, it’s essential to understand some common reasons why a device might not be detected:

  • Using a USB cable that only supports charging.
  • Missing or incorrect Vendor ID in the ~/.android/adb_usb.ini file.
  • USB Debugging not enabled on the device.
  • Conflicting software like EasyTether interfering with ADB.

Step-by-Step Troubleshooting

1. Check Your USB Cable

Ensure that your USB cable supports data transfer. Some cables are designed solely for charging, which can lead to connectivity issues. If in doubt, try using a different cable, preferably one that came with your Android device.

2. Enable USB Debugging

For your device to communicate with ADB, USB Debugging must be enabled. You can do this by going to Settings > About Phone and tapping on the Build Number seven times. This action will unlock the Developer Options menu, where you can enable USB Debugging.

3. Configure Vendor ID

If your device is still not detected, you may need to add your device’s Vendor ID to the ADB configuration file:

  1. Open the System Information application on macOS.
  2. Navigate to Hardware > USB and locate your device to find the Vendor ID.
  3. Add the Vendor ID to ~/.android/adb_usb.ini using the following command:
  4. echo 0x[VendorID] >> ~/.android/adb_usb.ini
  5. Restart ADB with the commands:
  6. adb kill-server; adb devices

4. Remove Conflicting Software

If you have software like EasyTether installed, it can interfere with ADB. Unload the extension using this command:

sudo kextunload /System/Library/Extensions/EasyTetherUSBEthernet.kext

Advanced Troubleshooting

For persistent issues, consider the following additional steps:

  • Switch USB ports if your device is not recognized.
  • Reboot both your macOS machine and Android device.
  • Ensure that any necessary drivers are installed, especially for specific brands like Samsung or Motorola.
