Crashing When Accessing a ViewModel from a Fragment in Android 14 with Hilt Dependency Injection

android hilt viewmodel kotlin

I'm refactoring my project and I'm collaborating on a project where I'm experiencing a crash when trying to access my ViewModel from a Fragment that uses Hilt for dependency injection... The behavior message I get is `java.lang.IllegalStateException: Fragment MyFragment did not return a ViewModel`. I've already annotated my Fragment with `@AndroidEntryPoint` and am using the following code to retrieve the ViewModel: ```kotlin class MyFragment : Fragment() { private val viewModel: MyViewModel by viewModels() override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { return inflater.inflate(R.layout.fragment_my, container, false) } override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) viewModel.someLiveData.observe(viewLifecycleOwner) { data -> // Handle data } } } ``` I've double-checked that my ViewModel is set up correctly with the `@HiltViewModel` annotation: ```kotlin @HiltViewModel class MyViewModel @Inject constructor(private val repository: MyRepository) : ViewModel() { val someLiveData: LiveData<MyData> = repository.getData() } ``` In my build.gradle file, I have the appropriate dependencies: ```groovy dependencies { implementation "com.google.dagger:hilt-android:2.42" kapt "com.google.dagger:hilt-compiler:2.42" implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03" implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.0" } ``` I have also included the necessary Hilt dependencies in my Application class: ```kotlin @HiltAndroidApp class MyApplication : Application() {} ``` Despite all of this, I still get the crash when the Fragment is created. It seems like Hilt isn't properly injecting the ViewModel. How can I fix this scenario? Any insights would be appreciated. For context: I'm using Kotlin on Windows. Thanks in advance! I'm working with Kotlin in a Docker container on Ubuntu 20.04. Thanks for taking the time to read this! I'm open to any suggestions. Any help would be greatly appreciated! I'm using Kotlin latest in this project. How would you solve this?
