New Updated Google Associate Android Developer Exam Dumps

1. What is a correct part of an Implicit Intent for sharing data implementation?

2. 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:

3. Select correct demonstration of WorkRequest cancellation.

4. 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.

5. 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:

6. 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?

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

8. As an example. In an Activity we have our TimerViewModel object (extended ViewModel), named mTimerViewModel. mTimerViewModel.timer 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?

9. LiveData.postValue() and LiveData.setValue() methods have some differences.

So if you have a following code executed in the main thread:

liveData.postValue("a"); liveData.setValue("b");

What will be the correct statement?

10. In our TeaViewModel class, that extends ViewModel, we have such prorerty:

val tea: LiveData<Tea>

An observer in our Activity (type of mViewModel variable in example is TeaViewModel) is set in this way:

mViewModel!!.tea.observe(this, Observer { tea: Tea? -> displayTea(tea) })

What will be a correct displayTea method definition?

11. For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences). Our preferences.xml file contains such item:

<SwitchPreference android:id="@+id/notification" android:key="@string/pref_notification_key"

android:title="@string/pref_notification_title"

android:summary="@string/pref_notification_summary"

android:defaultValue="@bool/pref_notification_default_value" app:iconSpaceReserved="false"/>

In our Fragment, we can dynamically get current notification preference value in this way:

12. For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences).

Our preferences.xml file contains such item:

<ListPreference android:id="@+id/order_by" android:key="@string/pref_sort_key"

android:title="@string/pref_sort_title" android:summary="@string/pref_sort_summary"

android:dialogTitle="@string/pref_sort_dialog_title" android:entries="@array/sort_oder"

android:entryValues="@array/sort_oder_value"

android:defaultValue="@string/pref_default_sort_value" app:iconSpaceReserved="false" />

In our Fragment, we can dynamically get current notification preference value in this way:

13. For example, we have a file in our raw folder app/src/main/res/raw/sample_teas.json.

To get an InputStream for reading it, from out Context context, we can do this:

14. For example, we have a BufferedReader reader, associated with the json file through InputStreamReader.

To get a file data we can do this:

15. 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:

16. An example. In our ViewModelFactory (that implements ViewModelProvider.Factory) we have an instance of our Repository, named mRepository. Our ViewModel has such constructor: class MyViewModel(private val mRepository: MyRepository) : ViewModel()...

Next, in our ViewModelFactory create ViewModel method (overriden) looks like this:

override fun <T : ViewModel?> create(modelClass: Class<T>): T {

return try {

//MISSED RETURN VALUE HERE”

} catch (e: InstantiationException) {

throw RuntimeException("Cannot create an instance of $modelClass", e)

} catch (e: IllegalAccessException) {

throw RuntimeException("Cannot create an instance of $modelClass", e)

} catch (e: NoSuchMethodException) {

throw RuntimeException("Cannot create an instance of $modelClass", e)

} catch (e: InvocationTargetException) {

throw RuntimeException("Cannot create an instance of $modelClass", e)

}

}

What should we write instead of “//MISSED RETURN VALUE HERE”?

17. What is demonstrated by the code below?

// RawDao.kt

@Dao

interface RawDao { @RawQuery

fun getUserViaQuery(query: SupportSQLiteQuery?): User?

}

// Usage of RawDao

...

val query =

SimpleSQLiteQuery("SELECT * FROM User WHERE id = ? LIMIT 1", arrayOf<Any>(sortBy))

val user = rawDao.getUserViaQuery(query)

...

18. What happens when you create a DAO method and annotate it with @Insert?

Example:

@Dao

interface MyDao {

@Insert(onConflict = OnConflictStrategy.REPLACE)

fun insertUsers(vararg users: User)

}

19. What do you want from Room when you create a DAO method and annotate it with @Update?

Example:

@Dao

interface MyDao {

@Update

fun updateUsers(vararg users: User)

}

20. What do you want from Room when you create a DAO method and annotate it with @Delete?

Example:

@Dao

interface MyDao {

@Delete

fun deleteUsers(vararg users: User)

}

21. To automate UI tests with Android Studio, you implement your test code in a separate Android test folder.

Folder could be named:

22. Once your test has obtained a UiObject object, you can call the methods in the UiObject class to perform user interactions on the UI component represented by that object.

You can specify such actions as: (Choose four.)

23. If you want to access a specific UI component in an app, use the UiSelector class. This class represents a query for specific elements in the currently displayed UI.

What is correct about it? (Choose two.)

24. Each time your test invokes onView(), Espresso waits to perform the corresponding UI action or assertion until the following synchronization conditions are met: (Choose three.)

25. Run your test in one of the following ways (select possible): (Choose three.)

26. To create a basic JUnit 4 test class, create a class that contains one or more test methods. A test method begins with the specific annotation and contains the code to exercise and verify a single functionality in the component that you want to test.

What is the annotation?

27. The Testing Pyramid, shown in the Figure, illustrates how your app should include the three categories of tests: small, medium, and large. Medium tests are integration tests that:

35. The Log class allows you to create log messages that appear in logcat. Generally, you could use the following log methods: (Choose five.)

36. Filter logcat messages. If in the filter menu, a filter option “Show only selected application”? means:
