使用 Hilt 注入實現接口的類的正確方法

Question

我有

BeatPlayer.kt

interface BeatPlayer {
   fun getSession(): MediaSessionCompat
   fun playSong(extras: Bundle = bundleOf(BY_UI_KEY to true))
   fun playSong(id: Long)
   fun playSong(song: Song)
 }

class BeatPlayerImplementation(
private val context: Application,
private val musicPlayer: AudioPlayer,
private val songsRepository: SongsRepository,
private val queueUtils: QueueUtils,
private val audioFocusHelper: AudioFocusHelper
) : BeatPlayer {
 .........

 }

音樂服務.kt

@AndroidEntryPoint
class MusicService :  CoroutineService(Main) {
   @Inject
  lateinit var beatPlayer: BeatPlayer
}

當我運行它說：

[Dagger/MissingBinding] 如果沒有 @Provides 注釋方法，則無法提供 BeatPlayer。

所以我添加了這個：

@Module
@InstallIn(SingletonComponent::class)
abstract class StorageModule {
@Singleton
@Binds
abstract fun bindBeatPlayer(beatPlayer: BeatPlayer): BeatPlayerImplementation
}

現在，我運行，它說：

錯誤：@Binds 方法的參數類型必須可分配給返回類型刀柄

如何正確操作？

Answer 1

我將根據@HenryTest 的評論回答我的問題。

存儲模塊.kt

@Module
@InstallIn(SingletonComponent::class)
abstract class StorageModule {
@Binds
abstract fun bindsPreferenceStorage(preferenceStorageImpl: 
PreferenceStorageImpl): PreferenceStorage

@Singleton
@Binds
abstract fun bindBeatPlayer(beatPlayer: BeatPlayerImplementation): 
BeatPlayer
}

現在提供 BeatPlayer 實現。

應用模塊.kt

 @Singleton
 @Provides
 fun providesBeatPlayerImplementation(@ApplicationContext context: 
 Context.,.,.,.) = 
 BeatPlayerImplementation(
    context, .., .., ..,  
 )

要么

在BeatPlayer 中實現

 class BeatPlayerImplementation @Inject constructor(
 @ApplicationContext private val context: Application,
 .....
 ) : BeatPlayer {
 .........
 }
