Resolving the “ADB Server Didn’t ACK” Issue with React-Native and Genymotion

Resolving the "ADB Server Didn't ACK" Issue with React-Native and Genymotion

17 December 2024 Stephan Petzl Leave a comment Tech-Help

When working with React-Native on Android and using Genymotion as your emulator, you might encounter an error message indicating that the “ADB server didn’t ACK.” This issue often arises due to conflicts between different versions of Android Debug Bridge (ADB) running simultaneously. In this article, we will guide you through the steps to resolve this problem effectively.

Understanding the Issue

The error message typically looks like this:

    
04:54:40 E/adb: error: could not install *smartsocket* listener: Address already in use
04:54:40 E/adb: ADB server didn't ACK
04:54:40 E/ddms: '/Users/yourname/Library/Android/sdk/platform-tools/adb,start-server' failed -- run manually if necessary
04:54:40 E/adb: * failed to start daemon *
04:54:40 E/adb: error: cannot connect to daemon
    
  

This error indicates that the ADB server failed to start, typically because another instance is already running. This can happen if Genymotion and your Android SDK are using different ADB versions.

Solution Steps

To resolve this issue, follow these steps:

Step 1: Align ADB Versions

  • First, check the version of ADB being used by your system and the Android SDK. Open a terminal and run the following commands:
      
adb version
cd /Path/to/Android/Sdk/platform-tools && ./adb version
      
    
  • If the versions differ, you need to update them. Remove the existing ADB executable from your system path and replace it with the one from the Android SDK:
  •       
    sudo rm /usr/bin/adb
    sudo cp /Path/to/Android/Sdk/platform-tools/adb /usr/bin/
          
        

    Step 2: Configure Genymotion

    • Ensure that Genymotion is configured to use the same Android SDK as your React-Native project. This can typically be done in the Genymotion settings under ADB configuration.

    Step 3: Restart ADB and Project

    • Restart the ADB server by executing the following commands:
          
    adb kill-server
    adb start-server
          
        
  • Then, try running your React-Native project again:
  •       
    react-native run-android
