For example, we have a file in our assets folder app/src/main/assets/sample_teas.json. To get an InputStream for reading it, from out Context context, we can try do this:

• A.val input = context!!.assets.open("sample_teas.json")
• B.val input = context!!.resources.openRawResource(R.raw.sample_teas)
• C.val input = context!!.resources.assets.open("sample_teas.json")

As an example. In an Activity we have our TimerViewModel object (extended ViewModel), named mTimerViewModel. mTimerViewModel.getTimer() method returns a LiveData<Long> value. What can be a correct way to set an observer to change UI in case if data was changed?

• A.mTimerViewModel.observe(new Observer<Long>() {
  @Override
  public void onChanged(Long aLong) {
  callAnyChangeUIMethodHere(aLong)
  }
  });
• B.mTimerViewModel.getTimer().getValue().toString().observe(new Observer<Long>() {
  @Override
  public void onChanged(Long aLong) {
  callAnyChangeUIMethodHere(aLong)
  }
  });
• C.mTimerViewModel.getTimer().observe(this, new Observer<Long>() {
  @Override
  public void onChanged(Long aLong) {
  callAnyChangeUIMethodHere(aLong)
  }
  });

To run a debuggable build variant you must use a build variant that includes

• A.minifyEnabled false in the build configuration

• C.debuggable true or debuggable false in the build configuration

Custom duration in milliseconds as a parameter for the setDuration method is available when you are working with:

• A.Snackbar
• B.Toast

The following code snippet shows an example of an Espresso test:

• A.@Test
  public void greeterSaysHello() {
  onView(withId(R.id.name_field)).do(typeText("Steve"));
  onView(withId(R.id.greet_button)).do(click());
  onView(withText("Hello Steve!")).compare(matches(isDisplayed()));
  }
• B.@Rule
  public void greeterSaysHello() {
  onView(withId(R.id.name_field)).do(typeText("Steve"));
  onView(withId(R.id.greet_button)).do(click());
  onView(withText("Hello Steve!")).check(matches(isDisplayed()));
  }
• C.@Test
  public void greeterSaysHello() {
  onView(withId(R.id.name_field)).perform(typeText("Steve"));
  onView(withId(R.id.greet_button)).perform(click());
  onView(withText("Hello Steve!")).check(matches(isDisplayed()));
  }
