我正在开发一个 Android 应用程序。我正在尝试将 hilt 与 workmanager 构造函数一起使用，但它不起作用并给了我这个错误：

2020-08-18 19:01:09.989 18125-18759/com. E/WM-WorkerFactory: Could not instantiate example.android.app.database.DeleteNotesWorker

这是工人阶级：

class DeleteNotesWorker @WorkerInject constructor(
    @Assisted context: Context,
    @Assisted workerParams: WorkerParameters,
    private val dao : NotesDao
) : CoroutineWorker(context, workerParams) {

    override suspend fun doWork(): Result {
        dao.deleteNotesInTrash()
         return Result.success()
    }


}

应用模块：

@Module
@InstallIn(ApplicationComponent::class)
object AppModule {

    @Singleton
    @Provides
    fun …
