Resolving Android Device Connection Issues in Eclipse

30 November 2024 Stephan Petzl Leave a comment Tech-Help

Experiencing issues with your Android device not appearing in Eclipse’s Android Device Chooser can be frustrating. This guide will walk you through several potential solutions to ensure your device is properly recognized, allowing you to continue with your development work seamlessly.

Common Reasons for Device Detection Failures

• Incorrect USB driver installation.
• Missing device permissions on your computer.
• Device connection settings not configured correctly.

Step-by-Step Troubleshooting Guide

Verify Device Recognition via ADB

Before diving into more complex solutions, ensure your device is recognized by ADB:

adb devices

If the output lists your device with question marks, it indicates a connection issue.

Configure USB Device Rules (Linux)

For Linux users, you may need to set up specific rules for your device:

1. Identify your device’s vendor ID using the command:

lsusb

2. Create a new rules file:

sudo vim /etc/udev/rules.d/51-android.rules

3. Add the following line, replacing ’04e8′ with your vendor ID:

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"

4. Apply the new rules:

sudo chmod a+r /etc/udev/rules.d/51-android.rules<br>sudo service udev reload

Driver Update for Windows Users

If you are using a Windows machine, follow these steps to update your device drivers:

1. Open Device Manager.
2. Find your Android device under the “Android Phone” section.
3. Right-click and select “Update Driver Software.”
4. Choose “Browse my computer for driver software.”
5. Select “USB Composite Device” if available, or navigate to the usb_driver folder in your Android SDK directory.

Ensure Correct Device Connection Mode

Check your device’s USB connection settings:

• Ensure your device is set to PTP (Camera) mode instead of MTP (Media Transfer Protocol).
• This setting is often found in the notification bar under USB connection options.

Additional Solutions

Sometimes, a simple change can resolve the issue:

• Try using a different USB cable or port.
• Restart both your computer and your Android device.
