Kamil Krzyk, thanks for sharing!

I don’t believe the following is a good way of getting the current activity though

public Activity getCurrentActivity() {        return ((TestApplication) InstrumentationRegistry.            getTargetContext().getApplicationContext()).getCurrentActivity();    }

Inside the Espresso test, one can do the following which is better:

@Nullable
protected Activity getActivityInstance() {
final Activity[] currentActivity = new Activity[1];
getInstrumentation().runOnMainSync(() -> {
Collection<Activity> resumedActivities = ActivityLifecycleMonitorRegistry.getInstance()
.getActivitiesInStage(Stage.RESUMED);
for (Activity act : resumedActivities) {
currentActivity[0] = act;
}
});

return currentActivity[0];
}

Do you have a Github repository for me to understand your tutorial better?
