Ch. 4 ViewModel Scoping

Android Programming (4th Edition) 4. Persisting UI State
1

I am following through the book and trying to fix the bug with GeoGuesser resetting on rotation. I followed the instructions to scope QuizViewModel to MainActivity but it doesn’t seem to be scoping to it. I do not see the message in logcat when it is initialized. This is the relevant code in Main and QuizViewModel:

MainActivity.kt:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    Log.d(TAG, "onCreate(Bundle?) called")
    setContentView(R.layout.activity_main)

    val provider: ViewModelProvider = ViewModelProviders.of(this)
    val quizViewModel = provider.get(QuizViewModel::class.java)
    Log.d(TAG, "Got a QuizVieModel: $quizViewModel")

QuizViewModel.kt

private const val TAG = “QuizViewModel”

class QuizViewModel : ViewModel() {

init {
    Log.d(TAG, "ViewModel instance created")
}

override fun onCleared() {
    super.onCleared();
    Log.d(TAG, "ViewModel instance about to be destroyed")
}

}

I have been looking over it to see if I made any spelling errors and unless I am blind, I do not think I have made any. Please let me know what I am doing wrong. I am using the same emulator as the book the Pixel 2 API 28.
