I am trying to use UI Automator Viewer and have been testing on a device with Android version 10 and on another device with Android 9. I'm following the tutorial here.
When I try and run UI Automator Viewer then click the button in the top left I get this error:
Error obtaining UI hierarchy
Reason: Unexpected error while obtaining UI hierarchy
Details:
java.lang.reflect.InvocationTargetException
In the command window I notice the following log:
11:39:38 E/Screenshot: Unsupported protocol: 2
In Android studio I have Android SDK Build-Tools version 30.0.2 installed.
I've tried restarting the viewer and still same issue. Also I'm not using Appium.
