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?

• A. Android loads graphics from res/drawable-small-land-stylus/
• B. Android loads graphics from res/drawable/
• C. Android loads graphics from res/drawable-ja/

We have a custom view that extends android.widget.ProgressBar. Our progress bar is not touchable, focusable, etc.: it just shows progress. Style for our custom progress bar extends
"Widget.AppCompat.ProgressBar.Horizontal". An item, named "progressDrawable", in our style, is a xml file . What we usually can see as a main single element in this xml file:

• A. An <ImageView> element with android:id="@+id/progress" identifier
• B. A State List (<selector> element )
• C. A Layer List (<layer-list> element) with items android:id="@+id/progress" and android:id="@+id/ background" inside it.

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

• A. for none of them
• B. for both of them
• C. Toast
• D. Snackbar

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"?

• A. modelClass.getConstructor(MyRepository::class.java)
  .newInstance(mRepository)
• B. modelClass.getConstructor()
  .newInstance(mRepository)
• C. modelClass.getConstructor(MyRepository::class.java)
  .newInstance()

By adding a RoomDatabase.Callback to the room database builder RoomDatabase.Builder (method addCallback(RoomDatabase.Callback callback)), we can: (Choose two.)

• A. handle database first time creation
• B. set the database factory
• C. handle database opening
• D. disable the main thread query check for Room
