When working with Appium and Android Studio on macOS, you may encounter an error while attempting to launch UIAutomatorViewer from the command line. This error often manifests with a message indicating issues with the Java Virtual Machine, such as:
Error: Could not create the Java Virtual Machine.
This issue can be particularly frustrating as it prevents the successful launch of UIAutomatorViewer, a key tool for inspecting UI components in Android applications. Fortunately, there’s a straightforward solution to this problem.
Solution: Downgrade to Java 8
The root cause of this error is often related to the version of Java installed on your system. UIAutomatorViewer and related Android tools have compatibility issues with Java 9 and above. To resolve this, you need to uninstall Java 9 and install Java 8 instead. Follow these steps:
- Uninstall Java 9: Use the Terminal or a Java uninstaller tool to remove Java 9 from your system.
- Download Java 8: Visit the official Oracle website or another trusted source to download Java 8.
- Install Java 8: Follow the installation instructions to set up Java 8 on your macOS.
Once Java 8 is installed, attempt to launch UIAutomatorViewer again. This should resolve the error and allow you to proceed with your testing tasks.
