android.os.BadParcelableException: ClassNotFoundException when unmarshalling

[plastiv]

Description

Asserting on activity result extra from ActivityScenario results in exception. This was not the case with ActivityTestRule.

Steps to Reproduce

2. Start "picker" activity with scenario = ActivityScenario.launch(intent)
3. Simulate result_ok with included parcelable extra
4. Assert on activity result intent extras (which triggers unmarshalling ClassNotFoundException exception) with

val activityResult = scenario.result!!
assertThat(activityResult, hasResultCode(RESULT_OK))
assertThat(activityResult, hasResultData(hasExtraWithKey(KEY_SELECTED_CITY)))

Expected Results

Assertion works

Actual Results

Exception similar to next one:

AndroidX Test and Android OS Versions

1.3.0 and sdk29

Link to a public git repo demonstrating the problem:

I need some guidance. I guess this repo should have already some tests which work on activity result verification. What are they? I would then extend them to include parcelable extra into activity result intent.

Current workaround

Set classloader explicitly before asserting result

val activityResult = scenario.result!!
activityResult.resultData.setExtrasClassLoader(this::class.java.classLoader)
assertThat(activityResult, hasResultCode(RESULT_OK))
assertThat(activityResult, hasResultData(hasExtraWithKey(KEY_SELECTED_CITY)))

Yes, it is reproducible. Are there any deadlines for when it will be fixed?

Can this be handled before the call？
