1. 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 fun onCreateOptionsMenu(menu: Menu): Boolean { menuInflater.inflate(

menu.menu_main, menu) return true }

override fun onOptionsItemSelected(item: MenuItem): Boolean { menuInflater.inflate(

menu.menu_main, menu) return super.onOptionsItemSelected(item) }

override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(

menu.menu_main) }

2. Custom views and directional controller clicks. In general, you should send an Accessibility Event whenever the content of your custom view changes.

For example, if a text value was changed in your custom view, you should emit an event of this type:

TYPE_WINDOWS_CHANGED

TYPE_VIEW_CONTEXT_CLICKED

TYPE_WINDOWS_CHANGED

TYPE_VIEW_TEXT_CHANGED

3. If you want the Database Inspector to automatically update the data it presents as you interact with your running app, check the Live updates checkbox at the top of the inspector window.

While live updates are enabled, what happens with the table in the inspector window?

It is still editable. You can modify data in a table by double-clicking a cell, typing a new value, and pressing Enter.

It becomes read-only and you cannot modify its values.

It becomes read-only, but you cannot see its updated values before updating the data by clicking the Refresh table button at the top of the inspector window.

4. “Set the activity content to an explicit view. This view is placed directly into the activity's view hierarchy. It can itself be a complex view hierarchy.”

This can be done by calling method:

findViewById

setContentView

setActionBar

setContentTransitionManager

setTheme

5. A content label sometimes depends on information only available at runtime, or the meaning of a View might change over time. For example, a Play button might change to a Pause button during music playback.

In these cases, to update the content label at the appropriate time, we can use:

View#setContentDescription(int contentDescriptionResId)

View#setContentLabel(int contentDescriptionResId)

View#setContentDescription(CharSequence contentDescription)

View#setContentLabel(CharSequence contentDescription)

6. DRAG DROP

Under the hood WorkManager uses an underlying job dispatching service based on the following criteria. You need to move services to the correct places.

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

minifyEnabled false in the build configuration

debuggable true or debuggable false in the build configuration

debuggable true in the build configuration

8. 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:

val input = context!!.resources.openRawResource(

raw.sample_teas)

val input = context!!.assets.open("sample_teas.json")

val input = context!!.resources.assets.open("sample_teas.json")

9. What statements about InputStreamReader (java.io.InputStreamReader) are correct? (Choose two.)

An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

An InputStreamReader is a bridge from character streams to byte streams: It reads characters using a specified charset and encodes them into bytes. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

Each invocation of one of an InputStreamReader's read() methods may cause one or more bytes to be read from the underlying byte-input stream. To enable the efficient conversion of bytes to characters, more bytes may be read ahead from the underlying stream than are necessary to satisfy the current read operation.

No any invocation of one of an InputStreamReader's read() methods can cause some bytes to be read from the underlying byte-input stream.

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

Our preferences.xml file contains such item:

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:

val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(

string.pref_sort_key), context!!.resources.getBoolean(

bool.pref_default_sort_value) )

val sortBy = PreferenceManager.getSharedPreferences(context).getString( context!!.getString(

string.pref_default_sort_value), context!!.getString(

string.pref_sort_key), )

val sortBy = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.resources.getBoolean(

bool.pref_default_sort_value), context!!.getString(

string.pref_sort_key) )

val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(

string.pref_sort_key), context!!.getString(

string.pref_default_sort_value) )

11. When your code execution reaches the breakpoint, Android Studio pauses execution of your app. You can then use the tools in the Debugger tab to identify the state of the app.

With Step Into you can

examine the object tree for a variable, expand it in the Variables view. If the Variables view is not visible

evaluate an expression at the current execution point

advance to the next line in the code (without entering a method)

advance to the first line inside a method call

advance to the next line outside the current method

continue running the app normally

12. If no any folder like res/anim-, res/drawable-, res/layout-, res/raw-

, res/xml- exist in the project.

Which folders are required in the project anyway? (Choose two.)

res/anim/

res/drawable/

res/layout/

res/raw/

res/xml/

13. What method should we use with Notification.Builder to supply a PendingIntent to be sent when the notification is clicked?

setContentInfo

setContentIntent

setDeleteIntent

14. For example, suppose that in a XML file (res/menu/menu_main.xml as an example), where menu items are described, we have such item:

...

android:id="@+id/action_settings"

android:orderInCategory="100"

android:title="@string/menu_action_settings"

app:showAsAction="never" />

...

Attribute “app:showAsAction” shows when and how this item should appear as an action item in the app bar.

What value “never” in this attribute means?

Only place this item in the app bar if there is room for it. If there is not room for all the items marked by this value, the items with the lowest orderInCategory values are displayed as actions, and the remaining items are displayed in the overflow menu.

Also include the title text (defined by android:title) with the action item. You can include this value along with one of the others as a flag set, by separating them with a pipe.

Never place this item in the app bar. Instead, list the item in the app bar's overflow menu.

Always place this item in the app bar. Avoid using this unless it's critical that the item always appear in the action bar. Setting multiple items to always appear as action items can result in them overlapping with other UI in the app bar.

The action view associated with this action item (as declared by android:actionLayout or android:actionViewClass) is collapsible.

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

@Rule public void greeterSaysHello() { onView(withId(

id.name_field)).do(typeText("Steve")); onView(withId(

id.greet_button)).do(click()); onView(withText("Hello Steve!")).check(matches(isDisplayed())); }

@Test public void greeterSaysHello() { onView(withId(

id.name_field)).perform(typeText("Steve")); onView(withId(

id.greet_button)).perform(click()); onView(withText("Hello Steve!")).check(matches(isDisplayed())); }

@Test public void greeterSaysHello() { onView(withId(

id.name_field)).do(typeText("Steve")); onView(withId(

id.greet_button)).do(click()); onView(withText("Hello Steve!")).compare(matches(isDisplayed())); }

16. If content in a PagedList updates, the PagedListAdapter object receives:

only one item from PagedList that contains the updated information.

one or more items from PagedList that contains the updated information.

a completely new PagedList that contains the updated information.

17. Filter logcat messages. If in the filter menu, a filter option “Edit Filter Configuration”? means:

Display the messages produced by the app code only (the default). Logcat filters the log messages using the PID of the active app.

Apply no filters. Logcat displays all log messages from the device, regardless of which process you selected.

Create or modify a custom filter. For example, you could create a filter to view log messages from two apps at the same time.

18. DRAG DROP

Move the major components of the Android platform to correct places in diagram.

19. Select correct statements about Hardware Abstraction Layer (HAL). (Choose two.)

The HAL provides standard interfaces that expose device hardware capabilities to the higher-level Java API framework.

The HAL function both as apps for users and to provide key capabilities that developers can access from their own app. For example, if your app would like to deliver an SMS message, you don't need to build that functionality yourself C you can instead invoke whichever SMS app is already installed to deliver a message to the recipient you specify

The HAL consists of multiple library modules, each of which implements an interface for a specific type of hardware component, such as the camera or bluetooth module. When a framework API makes a call to access device hardware, the Android system loads the library module for that hardware component.

Using a HAL, not using a Linux kernel, allows Android to take advantage of key security features and allows device manufacturers to develop hardware drivers for a well-known kernel.

20. In a class PreferenceFragmentCompat. As a convenience, this fragment implements a click listener for any preference in the current hierarchy.

So, in what overridden method we can handle that a preference in the tree rooted at this PreferenceScreen has been clicked?

onCreateLayoutManager

onCreatePreferences

onCreateRecyclerView

onPreferenceTreeClick

Page 3 of 4

21. 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.)

The message queue is empty.

The message queue is not empty.

There are some instances of AsyncTask currently executing a task.

There are no instances of AsyncTask currently executing a task.

Some developer-defined idling resources are not idle.

All developer-defined idling res

22. A class that you create for managing multiple data sources. In addition to a Room database, this class could manage remote data sources such as a web server.

It is about:

Activity/Fragment

ViewModel

Repository

Room database

23. In a class extended PreferenceFragmentCompat.

What method is used to inflate the given XML resource and add the preference hierarchy to the current preference hierarchy?

findPreference

getPreferenceManager

addPreferencesFromResource

setPreferenceScreen

24. Which build options in the Build menu to choose to delete all intermediate/cached build files.

Make Module

Generate Signed Bundle / APK

Rebuild Project

Clean Project

Make Project

25. “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 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);

26. Assume that an app includes a default set of graphics and two other sets of graphics, each optimized

for a different device setup:

res/drawable/

Contains default graphics. res/drawable-small-land-stylus/

Contains graphics optimized for use with a device that expects input from a stylus and has a QVGA

low- density screen in landscape orientation.

res/drawable-ja/

Contains graphics optimized for use with Japanese.

What happens if the app runs on a device that is configured to use Japanese and, at the same time, the device happens to be one that expects input from a stylus and has a QVGA low-density screen in landscape orientation?

Android loads graphics from res/drawable/

Android loads graphics from res/drawable-small-land-stylus/

Android loads graphics from res/drawable-ja/

27. As an example. In an Activity we have our TimerViewModel object (extended ViewModel), named mTimerViewModel. mTimerViewModel.getTimer() method returns a LiveData 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() { @Override public void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong) } });

mTimerViewModel.getTimer().observe(this, new Observer() { @Override public void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong) } });

mTimerViewModel.observe(new Observer() { @Override public void onChanged(Long aLong) { callAnyChangeUIMethodHere(aLong) } });

28. In application theme style, flag windowNoTitle () indicates:

whether this window should have an Action Bar in place of the usual title bar.

whether there should be no title on this window.

that this window should not be displayed at all.

whether this is a floating window.

whether this Window is responsible for drawing the background for the system bars.

29. Content labels.

What attribute to use to indicate that a View should act as a content label for another View?

android:contentDescription

android:hint

android:labelFor

30. 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.

style.Theme_LongText); ...

31. About running a debuggable build variant. Usually, you can just select the default "debug" variant that's included in every Android Studio project (even though it's not visible in the build.gradle file). But if you define new build types that should be debuggable, you must add ‘debuggable true’ to the build type.

Is that mostly true?

Yes.

No, if you define new build types that should be debuggable, you must add ‘debuggable false’

No, the debug variant should be visible in the build.gradle file anyway.

32. 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)

}

Room generates an implementation that inserts all parameters into the database in a single transaction.

Room modifies a set of entities, given as parameters, in the database. It uses a query that matches against the primary key of each entity.

Room removes a set of entities, given as parameters, from the database. It uses the primary keys to find the entities to delete.

33. What public methods are there in android.widget.Toast.Callback? (Choose two.)

onDismissed()

onToastHidden()

onShown()

onToastShown()

onToastCancelled()

34. Assume that you have the following situation:

The app code calls for R.string.text_a Three relevant resource files are available:

- res/values/strings.xml, which includes text_a in the app's default language, in this case English.

- res/values-mcc404/strings.xml, which includes text_a in the app's default language, in this case English.

- res/values-hi/strings.xml, which includes text_a in Hindi.

The app is running on a device that has the following configuration:

- The SIM card is connected to a mobile network in India (MCC 404).

- The language is set to Hindi (hi).

Which is the correct statement below?

Android loads text_a from res/values/strings.xml (in English)

Android loads text_a from res/values-mcc404/strings.xml (in English)

Android loads text_a from res/values-hi/strings.xml (in Hindi)

35. 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?

@RunWith

@LargeTest

@Rule

@Test

36. DRAG DROP

The diagram below shows a basic form of the recommended architecture for apps that use Architecture Components. The architecture consists of a UI controller, a ViewModel that serves LiveData, a Repository, and a Room database.

Drag modules to correct places.

37. If you want get a debuggable APK that people can install without adb, in Android Studio you can:

Select your debug variant and click Build Bundle(s) / APK(s) > Build APK(s).

Click the Run button from toolbar

Select your debug variant and click Analyze AP

38. 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; } ... }

39. What is the incorrect statement about Data Access Object (androidx.room.Dao)?

Data Access Objects are the main classes where you define your database interactions. They can include a variety of query methods.

The class marked with @Dao should either be an interface or an abstract class. At compile time, Room will generate an implementation of this class when it is referenced by a Database.

An abstract @Dao class can optionally have a constructor that takes a Database as its only parameter.

It is recommended to have only one Dao class in your codebase for all tables.
