In our TeaViewModel class, that extends ViewModel, we have such prorerty: val tea: LiveData

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?

A. private fun displayTea()

B. private fun displayTea(tea: Tea?)

C. private fun displayTea(tea: LiveData?)

D. private fun displayTea(tea: LiveData?)

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?

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

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

C. 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.

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/

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

C. Android loads graphics from res/drawable-ja/
