I'm learning to use Jetpack Compose and I was trying to follow a tutorial to create a Pokedex with Hilt and MVVM, everything was going well until I tried to implement the viewModel, when I injected it and tried to run the app, I got the title error ( Given component holder class com.example.pokedex.MainActivity does not implement interface dagger.hilt.internal.GeneratedComponent or interface dagger.hilt.internal.GeneratedComponentManager ), I already tried several solutions from the forum changing the way of injecting it but none of them has worked for me.
My code:
Pokedex Application:
@HiltAndroidApp
class PokedexApplication : Application() {
override fun onCreate() {
super.onCreate()
Timber.plant(Timber.DebugTree())
}
}
MainActivity
@AndroidEntryPoint
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
PokedexTheme {
val navController = rememberNavController()
NavHost(navController = navController,
startDestination = "pokemon_list_screen"
) {
composable("pokemon_list_screen") {
PokemonListScreen(navController = navController)
}
composable(
"pokemon_detail_screen/{dominantColor}/{pokemonName}",
arguments = listOf(
navArgument("dominantColor") {
type = NavType.IntType
},
navArgument("pokemonName") {
type = NavType.StringType
}
)) {
val dominantColor = remember {
val color = it.arguments?.getInt("dominantColor")
color?.let { Color(it) } ?: Color.White
}
val pokemonName = remember {
it.arguments?.getString("pokemonName")
}
}
}
}
}
}
}
AppModule
@Module
@InstallIn(SingletonComponent::class)
object AppModule {
@Singleton
@Provides
fun providePokemonRepository(
api: PokeApi
) = PokemonRepository(api)
@Singleton
@Provides
fun providePokeApi(): PokeApi {
return Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(BASE_URL)
.build()
.create(PokeApi::class.java)
}
}
Repository
@ActivityScoped
class PokemonRepository @Inject constructor (
private val api: PokeApi
) {
suspend fun getPokemonList(limit: Int, offset: Int): Resource<PokemonList> {
val response = try {
api.getPokemonList(limit, offset)
} catch (e: Exception) {
return Resource.Error(e.message.toString())
}
return Resource.Success(response)
}
}
Composable where I call the ViewModel
@Composable
fun PokemonList(
navController: NavController,
viewModel: PokemonListViewModel = hiltViewModel()
) {
val pokemonList by remember { viewModel.pokemonList }
val endReached by remember { viewModel.endReached }
val loadError by remember { viewModel.loadError }
val isLoading by remember { viewModel.isLoading }
LazyColumn(contentPadding = PaddingValues(16.dp)) {
val itemCount = if(pokemonList.size % 2 == 0) pokemonList.size / 2 else pokemonList.size / 2 + 1
items(itemCount) {
if (it >= itemCount - 1 && !endReached){
viewModel.loadPokemonPaginated()
}
PokedexRow(rowIndex = it, entries = pokemonList, navController = navController)
}
}
}
ViewModel (Just first code)
@HiltViewModel
class PokemonListViewModel @Inject constructor(
private val repository: PokemonRepository
) : ViewModel() {
private var curPage = 0
var pokemonList = mutableStateOf<List<PokedexListEntry>>(listOf())
var loadError = mutableStateOf("")
var isLoading = mutableStateOf(false)
var endReached = mutableStateOf(false)
init {
loadPokemonPaginated()
}
