Seeing a has no zero argument constructor runtime error when using androidx.lifecycle.viewmodel.compose.viewModel() 🧵

[Tash]

Happens ONLY when the ViewModel is in a separate gradle module

[Tash]

The activity:

// In Module A
@AndroidEntryPoint
class FooActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            // Breaks when FooViewModel is in a different gradle module
            val fooViewModel = viewModel<FooViewModel>()
            ScreenContent(state = fooViewModel.state)
        }
    }
}

[Tash]

The viewmodel:

// In Module B
@HiltViewModel
class FooViewModel @Inject constructor(
    private val getFoo: GetFoo
) : ViewModel() { ... }

[Tash]

Something to do with my setup or could it be a bug?

[Tash]

Hmm just updated dagger/hilt to 2.40.5, seems to have fixed it 🤔

Try hiltViewmodel() instead of viewModel() but first you must add the hilt-compose-navigation lib to your gradle

[Tash]

Had the same result with hiltViewModel() … the only thing that fixed it was bumping dagger version 😬
