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

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?

CodePudding user response：

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.

CodePudding user response：

From the documentation:

Hilt only supports fragments that extend androidx.Fragment.
