在后台和终止应用程序后，通知未与Workmanager一起显示

Question

我有一个待办事项列表应用程序，我想在前台和后台显示通知，我已经实现了代码，并且一切正常，但是当涉及到后台以及应用程序被杀死或设备重启后，通知没有不再显示，我不确定为什么会这样，这就是为什么我在这里寻求帮助的原因，并在此先感谢您提供的任何帮助。

val constraint = Constraints.Builder()
          .setRequiresCharging(false)
          .setRequiresStorageNotLow(false)
          .build()

      val oneTimeWorkRequest = OneTimeWorkRequestBuilder<NotificationWorkManager>()
          .setConstraints(constraint)
          .build()

      val workRequest  = WorkManager.getInstance(this).enqueue(oneTimeWorkRequest)
      var result = workRequest.state.value
      when(result){
          is SUCCESS ->{
            Toast.makeText(this,"Work Manager Success",Toast.LENGTH_SHORT).show()
          }
          is FAILURE ->{
              Toast.makeText(this,"Work Manager Failure",Toast.LENGTH_SHORT).show()

              var workUIDD = oneTimeWorkRequest.id
              WorkManager.getInstance(this).cancelWorkById(workUIDD)
          }
      }

 class NotificationWorkManager(var context: Context, workerParameters: WorkerParameters) : CoroutineWorker(context,workerParameters) {
    private var compat : NotificationManagerCompat? = null
    init {
        compat = NotificationManagerCompat.from(context)
    }

    override suspend fun doWork(): Result {
        return try {
            taskNotification() // this is the function to fire a notification
            Result.success()
        }catch (throwable : Throwable){
            Result.failure()
        }

    }
