About queries in DAO classes. Room verifies the return value of the query such that if the name of the field in the returned object doesn't match the corresponding column names in the query response, Room alerts you in one of the following two ways: (Choose two.)

Options

AIt gives a warning if no field names match.

BIt gives a warning if only some field names match.

CIt gives an error if no field names match.

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?

Options

AOnly 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.

BAlso 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.

CNever place this item in the app bar. Instead, list the item in the app bar's overflow menu.

DAlways 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.

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

MultipleChoice

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 create(modelClass: Class): 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''?

Options

AmodelClass.getConstructor()
.newInstance(mRepository)

BmodelClass.getConstructor(MyRepository::class.java)
.newInstance()

CmodelClass.getConstructor(MyRepository::class.java)
.newInstance(mRepository)

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

Options

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

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

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

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

Options

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

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

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

DWorkRequest 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();

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