Injection of an @HiltViewModel class is prohibited since it does not create a ViewModel instance correctly.
Access the ViewModel via the Android APIs (e.g. ViewModelProvider) instead.
Injected ViewModel: com.maxvision.myapplication.YourViewModel
com.maxvision.myapplication.YourViewModel is injected at
com.maxvision.myapplication.base.BaseActivity.viewModel
com.maxvision.myapplication.MainActivity is injected at
com.maxvision.myapplication.MainActivity_GeneratedInjector.injectMainActivity(com.maxvision.myapplication.MainActivity) [com.maxvision.myapplication.AppApplication_HiltComponents.SingletonC → com.maxvision.myapplication.AppApplication_HiltComponents.ActivityRetainedC → com.maxvision.myapplication.AppApplication_HiltComponents.ActivityC]
