Encountering the “ADB server didn’t ACK, failed to start daemon” error in Eclipse can be a frustrating experience, especially when you’re eager to proceed with Android development. This guide will walk you through several effective solutions to resolve this issue.

Understanding the Problem

This error typically arises after updating the Android SDK, and it indicates that the Android Debug Bridge (ADB) is unable to start properly. This can be due to various factors such as conflicting processes, incorrect SDK paths, or issues with the ADB server itself.

Step-by-Step Solutions

Basic Troubleshooting Steps

1. Kill the ADB Process:
   • Press CTRL+Shift+Esc to open the Task Manager.
   • Locate the adb.exe process and end (kill) it.
   • Alternatively, for command line users, execute adb kill-server from the command prompt.
2. Restart Eclipse:
   • Close Eclipse completely.
   • Restart Eclipse and try running your application again.

Advanced Troubleshooting

If the basic steps do not resolve the issue, consider these additional solutions:

• Check for Port Conflicts: Run netstat -aon | findstr 5037 in the command prompt to check if any other process is using the port 5037. If found, kill the process.
• Update Genymotion Settings: If using Genymotion, ensure it uses the same ADB as your Android SDK by updating the Genymotion settings.
• Check adb_usb.ini: Ensure there’s no newline at the end of the adb_usb.ini file located in the .android directory.

Common Causes and Solutions

Various applications or settings can cause this issue. Here are a few common scenarios and their solutions:

• Genymotion Interference: Ensure that Genymotion is configured to use the Android SDK’s ADB.
• Port 5037 in Use: Other applications may be using the ADB port. Identify and terminate these processes using tools like Process Explorer.
