为什么Uiautomator在getUiDevices（）中崩溃？

Question

i am trying to write a testing tool: create a thread in MainActivity and call Uiautomator functions to scan and analyze the UI components. is that possible? why it always crashes in getUiDevice()? thanks!

Answer 1

First of all, UiAutomatorTestCase is deprecated and you should use UiDevice.getInstance() .

Getting the UiDevice requires an Instrumentation instance that cannot be obtained from the same Activity, that's why you need to do it from a test run from adb .
