code: public static <T extends Activity> ActivityController<T> buildActivity(Class<T> activityClass) {
      return buildActivity(activityClass, null);
    }
docs: Creates a ActivityController for the given activity class.
  
  <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.
