Encountering the “ADB server version doesn’t match this client” error can be a common issue for developers working with Android devices, particularly when using tools like Appium for automation. This error typically arises due to a mismatch between the ADB versions on your development machine and the connected device or emulator. Here, we provide a step-by-step guide to troubleshoot and resolve this issue effectively.
Understanding the Error
The error message usually reads as follows:
adb server version (31) doesn't match this client (36); killing...
This indicates that the ADB server version running on your system is incompatible with the ADB client version trying to connect. This can result from having multiple ADB installations on your machine or using third-party tools that include their own ADB versions.
Step-by-Step Solutions
Solution 1: Sync ADB Versions on Ubuntu
If you’re using an Ubuntu-based OS, you can align the ADB versions by following these steps:
- Terminate the ADB server:
- Copy the ADB executable from your Android SDK to the system path:
- Make the ADB executable:
- Restart the ADB server:
adb kill-server
sudo cp ~/Android/Sdk/platform-tools/adb /usr/bin/adb
sudo chmod +x /usr/bin/adb
adb start-server
Solution 2: Adjust GenyMotion Settings
If you are using GenyMotion, you might need to configure it to use your custom Android SDK tools:
- Open GenyMotion settings.
- Navigate to the ADB tab.
- Select “Use custom Android SDK Tools” and browse to your installed SDK location.
Solution 3: Remove Redundant ADB Installations
Having multiple ADB installations can cause conflicts. Ensure you only have one ADB version active:
- Check for multiple ADB versions using the Application Monitor.
- Ensure the active ADB is the one located in your Android SDK folder.
- Delete or rename other ADB installations, such as those from third-party applications.
Additional Tips
For Windows users, it’s often helpful to check the Task Manager for running ADB processes. Ensure you kill these processes before restarting ADB from your Android Studio path.
