I can't run tests in project ui/BasicSample

[sevenfirezzz]

I can install the app and use it. But when I want to run a test, it shows error like this:

Illegal character in opaque part at index 11: jar:file:D:\04_myproject\official\testing-samples-master\ui\espresso\BasicSample\app\build\intermediates\apk_for_local_test\debugUnitTest\packageDebugUnitTestForUnitTest\apk-for-local-test.ap_

What should I do ?

What's the command you tried to run, and can you provide the full error message?

I just import the project and click the run button(left beside ChangeTextBehaviorLocalTest.class in Android Studio) . This is all I get, just one line error message.
