Appium 测试使用 java 11 执行，而 uiautomatorviewer 抛出错误。 java 11 是否支持 uiautomatorviewer？

Question

Error while executing UIAUTOMATORVIEWER with Java11 installed and env path set right. I'm able to execute the appium tests with java11 though.

ERROR: No suitable Java found. In order to properly use the Android Developer
Tools, you need a suitable version of Java JDK installed on your system.
We recommend that you install the JDK version of JavaSE, available here:
  http://www.oracle.com/technetwork/java/javase/downloads

If you already have Java installed, you can define the JAVA_HOME environment
variable in Control Panel / System / Avanced System Settings to point to the
JDK folder.

You can find the complete Android SDK requirements here:

Edit: uiautomatorviewer works with java8, any workaround for java11?

Answer 1

This error has nothing to do with UIAutomatorViewer, but since it is an old tool it can rely on 32-bit JDK. You can check this answer for a fix.

If you are using Appium, UIAutomatorViewer is obviously a bad choice since Appium no longer use original UIAutomator under the hood: it was deprecated in favour of UiAutomator2 and Espresso drivers

You better try official Appium desktop instead
