code: public static <T extends Activity> ActivityController<T> buildActivity(
        Class<T> activityClass, Intent intent) {
      return ActivityController.of(ReflectionHelpers.callConstructor(activityClass), intent);
    }
docs: Creates a ActivityController for the given activity class with the intent.
  
  <p>Note: the activity class is not determined by the intent.
  
  <p>Consider using {@link androidx.test.core.app.ActivityScenario} instead, which provides
  higher-level, streamlined APIs to control the lifecycle and it works with instrumentation tests
  too.
