ActivityScenario "close()" doesn't work as expected

[gustavobarbosab]

Description

I'm running an instrumented test using ActivityScenario, so I launch the test, and after the test finishes, I call the method close() of the ActivityScenario.

Then, I received the following error:

java.lang.AssertionError: Activity never becomes requested state "[DESTROYED]" (last
                  lifecycle transition = "RESUMED")

I don't know exactly why, but every time that I move the scenario to state DESTROYED the test crashes with the exception above.
When I remove the method "close" calling, the test starts to work as expected.

Steps to Reproduce

• Create an instrumented test for an Activity
• Starts the test using the method "ActivityScenario.launch"
• Closes the scenario using an "@after" JUnit annotation
• The crash will happen

Some libraries used:

• Mockk
• An abstraction of MockWebServer

Expected Results

• Test pass without problems

Actual Results

• Test crashing when calling close method.

Can you provide a code sample that repros the problem

[gustavobarbosab]

@brettchabot I have these tests in a private project, but I'm creating an open-source project to exemplify it and reproduce the error.

I have tried a lot of changes to understand why the error is happening, but I wasn't able. If I use the deprecated ActivityTestRule the test is executed successfully, but when using ActivityScenario the error happens in the moment that I call the method close.

I saw a related problem in another opened issue: #143

As soon as possible, I send a snippet of code here...
