Question 64

By default, the notification's text content is truncated to fit one line. If you want your notification to be longer, for example, to create a larger text area, you can do it in this way:

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID).setContentText("Much longer text that cannot fit one line...").setStyle(new NotificationCompat.BigTextStyle().bigText("Much longer text that cannot fit one line..."))

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID).setContentText("Much longer text that cannot fit one line...").setLongText("Much longer text that cannot fit one line..."))

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID).setContentText("Much longer text that cannot fit one line...") .setTheme(android.R.style.Theme_LongText); ...

Question 65

"workManager" is an instance of WorkManager. Select correct demonstration of WorkRequest cancellation:

workManager.enqueue(new OneTimeWorkRequest.Builder(FooWorker.class).build());

WorkRequest request = new OneTimeWorkRequest.Builder(FooWorker.class).build(); workManager.enqueue(request);LiveData<WorkInfo> status = workManager.getWorkInfoByIdLiveData(request.getId()); status.observe(...);

WorkRequest request = new OneTimeWorkRequest.Builder(FooWorker.class).build(); workManager.enqueue(request);workManager.cancelWorkById(request.getId());

WorkRequest request1 = new OneTimeWorkRequest.Builder(FooWorker.class).build();WorkRequest request2 = new OneTimeWorkRequest.Builder(BarWorker.class).build(); WorkRequest request3 = new OneTimeWorkRequest.Builder(BazWorker.class).build(); workManager.beginWith(request1, request2).then(request3).enqueue();

WorkRequest request = new OneTimeWorkRequest.Builder(FooWorker.class).build(); workManager.enqueue(request); workManager.cancelWork(request);

Question 66

In general, you should send an AccessibilityEvent whenever the content of your custom view changes. For example, if you are implementing a custom slider bar that allows a user to select a numeric value by pressing the left or right arrows, your custom view should emit an event of type TYPE_VIEW_TEXT_CHANGED whenever the slider value changes. Which one of the following sample codes demonstrates the use of the sendAccessibilityEvent() method to report this event.

@Override public boolean dispatchPopulateAccessibilityEvent(AccessibilityEvent event) { boolean completed = super.dispatchPopulateAccessibilityEvent(event); CharSequence text = getText(); if (!TextUtils.isEmpty(text)) { event.getText().add(text); return true;}return completed;}

@Override public boolean onKeyUp (int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) { currentValue--;sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED); return true;}

@Override public boolean onKeyUp (int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_ENTER) { currentValue--;sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_CONTEXT_CLICKED); return true;}

The easiest way of adding menu items (to specify the options menu for an activity) is inflating an XML file into the Menu via MenuInflater. With menu_main.xml we can do it in this way:

@Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); return true;}

@Override public boolean onOptionsItemSelected(MenuItem item) { getMenuInflater().inflate(R.menu.menu_main, menu); returnsuper.onOptionsItemSelected(item); }

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.menu.menu_main); }

Question 68

Android Tests. You can use the childSelector() method to nest multiple UiSelector instances. For example, the following code example shows how your test might specify a search to find the first ListView in the currently displayed UI, then search within that ListView to find a UI element with the text property Apps. What is the correct sample?

UiObject appItem = device.findObject(new UiSelector().className(ListView.class).instance(1).childSelector(new UiSelector().text("Apps")));

UiObject appItem = device.findObject(new UiSelector().className("android.widget.ListView").instance(0).childSelector(new UiSelector().text("Apps")));

UiObject appItem = device.findObject(new UiSelector().className("android.widget.ListView").instance(new UiSelector().text("Apps")));

Question 69

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

@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())); }

@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())); }

@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())); }

Question 70

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?

mTimerViewModel.getTimer().getValue().toString().observe(new Observer<Long>() { @Overridepublic void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong)}});

mTimerViewModel.getTimer().observe(this, new Observer<Long>() { @Overridepublic void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong)}});

mTimerViewModel.observe(new Observer<Long>() { @Overridepublic void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong)}});
