Connecting Your Android Device to USB for Debugging in Android Studio

Connecting Your Android Device to USB for Debugging in Android Studio

22 April 2024 Stephan Petzl Leave a comment Tech-Help

Debugging your Android application on a real device can be an essential part of the development process. However, sometimes when you connect your device to your computer via USB, Android Studio may not recognize it, displaying a “USB device not found” error. This can be frustrating, but there are several steps you can take to resolve the issue.

Switch USB Connection Mode

Some devices may not be recognized by Android Studio if they are connected as a media device using the Media Transfer Protocol (MTP). To resolve this:

  1. Look for a notification on your device that says “Connected as a media device.”
  2. Select this notification to change the USB options.
  3. Switch from “Media Device (MTP)” to “Camera (PTP)” mode.

This change can prompt your development environment to detect and connect to your device.

Update or Install Device Drivers

If switching the USB mode doesn’t work, the next step is to check the drivers on your computer:

  1. Go to Control Panel > Hardware and Sound > Device Manager.
  2. Look for any devices showing an error, often listed as an “Unknown USB Device.”
  3. Select the device and try to update the drivers.

Check USB Cable and Port

It’s important to use a USB cable that supports data transfer, not just charging. If you’re using a USB Type-C cable, ensure it has both charging and data transfer capabilities. Additionally, try using an official cable from your device’s manufacturer, as some third-party cables may not work correctly.

Restart Your Device

Simply restarting your device can sometimes resolve connectivity issues. Upon rebooting, your device may prompt you to trust the computer for debugging purposes.

Install OEM USB Drivers

If the above steps do not work, you may need to install OEM USB drivers for your specific device. You can usually find these on your device manufacturer’s official website or through the Android SDK Manager.

Try Different USB Port or Computer

If your device is still not recognized, try connecting it to a different USB port or another computer. This can help identify if the problem is with the USB port or your development setup.

Enable USB Debugging

Ensure that USB debugging is enabled on your device. This setting can be found in the Developer Options menu. If you have recently updated your device, check that USB debugging is still enabled, as it can sometimes be disabled during an update.
