Resolving 'adb.exe,start-server' Failed Error in Android Studio

21 May 2024 Stephan Petzl Leave a comment Tech-Help

Encountering the “adb.exe,start-server” failed error in Android Studio can be frustrating, especially when you’re eager to test your application. This guide provides a step-by-step solution to address this issue effectively.

Understanding the Issue

This error typically occurs when the Android Debug Bridge (ADB) server cannot start, often due to port conflicts or other processes using the same port. The primary port in question is tcp:5037.

Step-by-Step Solution

1. Close Conflicting Processes

First, ensure that there are no conflicting processes using the ADB port. Here’s how you can do this:

  • Close Android Studio and any emulators you are using.
  • Open Task Manager (Ctrl + Shift + Esc) and locate adb.exe in the list of processes.
  • End the adb.exe process.

2. Restart ADB Integration

Once you’ve closed the conflicting processes, restart the ADB integration in Android Studio:

  • Open Android Studio.
  • Navigate to Tools > Android and uncheck Enable ADB Integration.
  • Check the Enable ADB Integration option again.

3. Restart Genymotion Emulator (If Applicable)

If you’re using the Genymotion emulator, follow these steps:

  • Ensure Genymotion is closed.
  • Restart the ADB integration as described above.
  • Open Genymotion and start your virtual device again.

4. Alternative Approach: Change ADB Port

If the issue persists, consider changing the ADB port:

  • Open a command prompt and type adb nodaemon server. If you see the message cannot bind 'tcp:5037', proceed to the next step.
  • Run netstat -ano | findstr 5037 to identify the process ID (PID) using the port.
  • Use taskkill /pid [PID] -f to kill the process.
  • Restart Android Studio and ADB integration.
