无法解析"dagger.hilt.android.internal.lifecycle.DefaultActivityViewModelFactory"

Question

我花了整整一周的时间试图将hilt依赖项注入添加到我的示例note应用程序中，android工作室一直在向我抛出一个又一个错误。无论如何，这让我很生气，在AppModule中，我一直试图将我的房间数据库注入应用程序存储库，然后将我的应用程序repo注入用例类，最后将用例类注入sharedViewModel这就是我的AppModule对象：

@Module
@InstallIn(SingletonComponent::class)
object AppModule {
@Provides
@Singleton
fun provideNoteDatabase(app: Application): NoteDatabase {
return Room.databaseBuilder(
app,
NoteDatabase::class.java,
NoteDatabase.DATABASE_NAME
).build()
}
@Provides
@Singleton
fun provideNoteRepository(db: NoteDatabase): NotesRepo {
return RepoImplementation(db.noteDao())
}
@Provides
@Singleton
fun provideNoteUseCase(repo: NotesRepo): NoteUseCase {
return NoteUseCase(
getNotesUseCase = GetNotesUseCase(repo),
deleteNoteUseCase = DeleteNoteUseCase(repo),
updateNoteUseCase = UpdateNoteUseCase(repo),
insertNoteUseCase = InsertNoteUseCase(repo)
)
}
}

这是我的应用程序类：

@HiltAndroidApp
class Application : Application()

我的编辑片段：

@AndroidEntryPoint
class EditFragment : Fragment() {
private var _binding: FragmentEditBinding? = null
private val binding get() = _binding!!
private val viewModel: SharedViewModel by activityViewModels()
//...
}

我的另一个片段：

@AndroidEntryPoint
class MainFragment : Fragment() {
private  var _binding: FragmentMainBinding? = null
private val binding get() = _binding!!
private val viewModel: SharedViewModel by activityViewModels()
//...
}

顺便说一句，我的MainActivity也用@AndroidEntryPoint注释
我著名的viewModel:

@HiltViewModel
class SharedViewModel @Inject constructor(private val noteUseCase: NoteUseCase) :
ViewModel() {...} 

这是项目级别的构建.gradle:

buildscript {
repositories {
google()
mavenCentral()
}
dependencies {
def nav_version = "2.5.2"
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
classpath 'com.google.dagger:hilt-android-gradle-plugin:2.44'

和模块级构建.gradle:

如果有人能帮我找出问题所在并解释原因，我将非常感谢他。我需要通过这个考试，这样我才能在我的职业生涯中提高水平。

Answer 1

删除以下不推荐使用的依赖项：

implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"

(自dagger-2.34版本以来已弃用(

证明：https://github.com/google/dagger/releases/tag/dagger-2.34

同时尝试升级您的生命周期版本，如下所示：

def lifecycle_version = "2.5.1"

在build.gradle(app(中的依赖项部分后添加以下行：

kapt {   correctErrorTypes true }
