android.os.BadParcelableException: ClassNotFoundException when unmarshalling
Description
Asserting on activity result extra from ActivityScenario results in exception. This was not the case with ActivityTestRule.
Steps to Reproduce
- Start "picker" activity with
scenario = ActivityScenario.launch(intent) - Simulate result_ok with included parcelable extra
- 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:
android.os.BadParcelableException: ClassNotFoundException when unmarshalling: my.package.ParcelableAutoCompleteCity

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?
