'Dagger-Hilt @AndroidEntryPoint is not working with BottomSheetDialogFragment()

I am using ViewModel inside BottomSheetDialogFragmet() so I have to mark my BottomSheet with @AndroidEntryPoint.

@AndroidEntryPoint
class SearchAddressDialog : BottomSheetDialogFragment() {

    private val viewModel: MyAddressesViewModel by viewModels()
    
    ......
}

But when I tried to build my project it is giving me this error:

Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing 
org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
> java.lang.reflect.InvocationTargetException (no error message)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option 
to get more log output. Run with --scan to get full insights.

And here is my output for run with --stacktrace

If I delete the @AndroidEntryPoint above my BottomSheetFragmen() it is building and installing the app. But when I try to open the bottomSheet the app is crashing as I injected my repositories to the ViewModel:

@AndroidEntryPoint is working without errors on other ordinary Fragments.

UPDATE:

Here is my view model:

@HiltViewModel
class MyAddressesViewModel @Inject constructor(
   private val repository: AddressRepository,
   private val geocoderRepository: GeocoderRepository
) : ViewModel() {}

UPDATE 2: Right now I am annotating BottomSheetDialogFragment() and it is giving me errors while building.

And If I change this

@AndroidEntryPoint
class SearchAddressDialog : BottomSheetDialogFragment(){

to this

@AndroidEntryPoint
class SearchAddressDialog : Fragment() {

it is working perfectly fine.

Can I actually annotate BottomSheetDialogFragment() with @AndroidEntryPoint?

UPDATE 3:

Here is my BottomSheetDialogFragment

Solution 1:^[1]

After long research, I couldn't solve the @AndroidEntryPoint problem. And I have come up with this: I just pass my ViewModel to my BottomSheetDialogFragment on its constructor:

class SearchAddressDialog(
    private val viewModel: MyAddressesViewModel
) : BottomSheetDialogFragment() {
    ........ 
}

And I opened my dialog like this:

val dialog = SearchAddressDialog(viewModel)
dialog.show(childFragmentManager, SearchAddressDialog.TAG)

I have used the ViewModel of the current fragment.

Solution 2:^[2]

Did you add @Inject annotation on
AddressRepository and GeocoderRepository classes constructors? maybe you forget to annotate the constructor of the dependent object of your ViewModel class. because of it Hilt/Dagger is unable to resolve the dependency tree.

If this is the case, annotate all dependent class constructors with @Inject the problem will be resolve.

Solution 3:^[3]

First of all, I hope you added hilt-android-gradle-plugin in your project.

Secondly, there was an issue in dagger-hilt long ago regarding this inheritance dependency but it's already been fixed since 2.28. You can see more details in this link. https://github.com/google/dagger/issues/1910

So, for your case without adding @AndroidEntryPoint to BottomSheetDialogFragment should work but did you also try adding with this? Did it work that way?

Also, can you please share your BottomSheetDialogFragment class?

@AndroidEntryPoint & @HiltViewModel

works perfectly!

Here is my bottom sheet fragment and view model.

@AndroidEntryPoint
class BottomSheetFragment : BottomSheetDialogFragment() {
    companion object {
        const val TAG = "BottomSheetFragment"
    }

    private val viewModel by viewModels<BottomSheetFragmentViewModel>()
    private var _binding: BottomSheetFragmentBinding? = null
    private val binding get() = _binding!!

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?,): View {
        _binding = BottomSheetFragmentBinding.inflate(inflater, container, false)
        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        viewModel.test()
    }
}

@HiltViewModel
class BottomSheetFragmentViewModel @Inject constructor(
    private val localData: LocalRepository,
    private val remoteData: RemoteRepository,
) : BaseViewModel() {

    fun test() {}
}

and finally opening it from another fragment like this:

BottomSheetFragment().show(childFragmentManager, BottomSheetFragment.TAG);

Note: using dagger & hilt version 2.41

Hope this will help! Happy coding!!

From the documentation:

Hilt only supports fragments that extend androidx.Fragment.
