How to Access Activity from ActivityScenarioRule

Issue

I am using ActivityScenarioRule for Espresso UI Testing and I wanted to get access to the method getStringArray(), calling which requires the Activity . So, is there any way to retrieve the Activity by the ActivityScenarioRule , maybe something similar to getActivity in ActivityTestRule.

@Rule
    public ActivityScenarioRule activityScenarioRule = new ActivityScenarioRule<>(MainActivity.class);

I am not using ActivityTestRule, because it is deprecated!

Solution

Since it appears you're using Java, here's how you'd do it:

@Rule
ActivityScenarioRule<MainActivity> activityScenarioRule = new ActivityScenarioRule<>(MainActivity.class);

@Test
public void test() {
    activityScenarioRule.getScenario().onActivity(activity -> {
        // use 'activity'.
    });
}

Please read the documentation for more info on these new ways of interacting with the activity under test.
