Strange NullPointerException in LiveData Observer with Room Database on Android 14
I'm updating my dependencies and I'm trying to implement I'm working with a frustrating `NullPointerException` when trying to observe a LiveData object from my Room database in my Android app targeting API level 34..... The scenario arises when I attempt to update the UI with the data changes. Here's the relevant part of my code: ```kotlin class MyViewModel(application: Application) : AndroidViewModel(application) { private val repository: MyRepository = MyRepository(application) val myData: LiveData<List<MyEntity>> = repository.getAllEntities() } class MyActivity : AppCompatActivity() { private lateinit var viewModel: MyViewModel override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) viewModel = ViewModelProvider(this).get(MyViewModel::class.java) viewModel.myData.observe(this, { data -> // scenario occurs here myRecyclerView.adapter = MyAdapter(data) }) } } ``` The exact behavior message I receive is `java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.List com.example.MyEntity.getData()' on a null object reference`. I have verified that the `LiveData` object is being populated correctly when I check the database directly. I've also tried using `viewModelScope.launch` to ensure any data fetching is happening in the correct coroutine scope. I have created the database and DAO properly and am using the latest version of Room (2.4.3). This scenario didn't occur on Android 13, so I suspect there's something specific with the way LiveData works in Android 14. I am also using Kotlin Coroutines for asynchronous operations. Any thoughts on what might be going wrong? How can I ensure that my `myData` is never null when I attempt to observe it? The project is a REST API built with Kotlin. I'd love to hear your thoughts on this. My development environment is Debian. Thanks in advance!
