android - Android Hilt：找不到符号 DaggerBaseApplication_HiltComponents_SingletonC.builder()

Question

我正在尝试使用 CoroutineWorker 来安排一些工作，在这些工作中我将读取 json 文件并更新首选项管理器。

问题是我收到以下错误：

Hilt_BaseApplication.java:20：错误：找不到符号返回 DaggerBaseApplication_HiltComponents_SingletonC.builder() ^ 符号：变量 DaggerBaseApplication_HiltComponents_SingletonC

BaseApplication： @HiltAndroidApp 类 BaseApplication：Application()，Configuration.Provider {

@Inject
lateinit var workerFactory: HiltWorkerFactory

override fun onCreate() {
    super.onCreate()

    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)

    Timber.plant(Timber.DebugTree())

    NewsRepository.readNews()

    scheduleWorker()
}

private fun scheduleWorker(){
    val constraints = Constraints.Builder()
        .setRequiredNetworkType(NetworkType.CONNECTED)
        .build()

    val checkPatchWR = PeriodicWorkRequestBuilder<CheckPatchWorker>(15, TimeUnit.MINUTES, 10, TimeUnit.MINUTES)
        .setConstraints(constraints)
        .build()

    val reminderWR = PeriodicWorkRequestBuilder<RemindMeToWorkWorker>(2, TimeUnit.HOURS, 30, TimeUnit.MINUTES).build()

    WorkManager.getInstance(this).enqueue(checkPatchWR)
    WorkManager.getInstance(this).enqueue(reminderWR)

    Timber.d("Setup the worker !")
}

override fun getWorkManagerConfiguration(): Configuration = Configuration.Builder().setWorkerFactory(workerFactory).build()

}

CheckPatchWorker：

@HiltWorker
class CheckPatchWorker @AssistedInject constructor
    (
        @Assisted private val appContext: Context,
        @Assisted workerParameters: WorkerParameters,
        private val preferenceManager: PreferencesManager
    ): CoroutineWorker(appContext, workerParameters){

    val patchesUrl = "https://ddragon.leagueoflegends.com/api/versions.json"

    override suspend fun doWork(): Result {


        val patch = readLastPatchNotes()

        preferenceManager.patchFlow.collect {
            val lastPatch = it.yes

            if(!(patch.equals(lastPatch))){
                var builder = NotificationCompat.Builder(appContext, Constants.CHANNEL_PATCH_ID)
                    .setSmallIcon(R.drawable.challenger_1)
                    .setContentTitle("Patch notes")
                    .setContentText("A new version of patch notes was released ! Come check it out !")
                    .setPriority(NotificationCompat.PRIORITY_DEFAULT)
                    .setAutoCancel(true)
                    .setStyle(
                        NotificationCompat.BigTextStyle()
                            .bigText("New patch notes $lastPatch !!!! "))

                val pendingIntent = NavDeepLinkBuilder(appContext)
                    .setComponentName(MainActivity::class.java)
                    .setGraph(R.navigation.navigation_graph)
                    .setDestination(R.id.newsFragment)
                    .setArguments(bundleOf("worker" to "News"))
                    .createPendingIntent()

                builder.setContentIntent(pendingIntent)

                createNotificationChannel(builder)

                preferenceManager.updatePatch(lastPatch)
            }
        }




        return Result.success()
    }

    private fun readLastPatchNotes(): String {
        val jsonArticles = JSONArray(URL(patchesUrl).readText())

        return jsonArticles.getString(0)
    }

    fun createNotificationChannel(builder: NotificationCompat.Builder) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val name = Constants.CHANNEL_PATCH_ID
            val descriptionText = "Patch notes"
            val importance = NotificationManager.IMPORTANCE_DEFAULT
            val channel = NotificationChannel(Constants.CHANNEL_PATCH_ID, name, importance).apply {
                description = descriptionText
            }
            // Register the channel with the system
            val notificationManager: NotificationManager = appContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            notificationManager.createNotificationChannel(channel)

            notificationManager.notify(0, builder.build())
        }
    }
