Комната и отладка не работают в WorkManager?

Question

Custom WorkerManager

class CustomWorker(
val
context: Context, workerParams: WorkerParameters
) : Worker(context, workerParams) {
override fun doWork(): Result {

    val appDao = AppDatabase.getInstance(context).appDao()

    appDao.deleteAllRecords().subscribeOn(Schedulers.io())
        .observeOn(Schedulers.io()).subscribe(object : CompletableObserver {
            override fun onComplete() {
                Log.d("WorkManager", "onComplete")
            }

            override fun onSubscribe(d: Disposable) {
                Log.d("WorkManager", "onSubscribe")
            }

            override fun onError(e: Throwable) {
                Log.d("WorkManager", "onError")
            }

        })
  Log.d("WorkManager", "WorkManager")
           Looper.prepare()
           context.toast("Hellow")
           Looper.loop().
    return Result.success()
    }
}

Вызов WorkManager

fun createWorkerForClearingDb() {
    val oneTimeWorkRequest =
        OneTimeWorkRequest.Builder(CustomWorker::class.java)
            .setInitialDelay(2L, TimeUnit.HOURS).build()
    WorkManager.getInstance().beginUniqueWork(
        AppConstants.Work.DELETE_TASK,
        ExistingWorkPolicy.REPLACE,
        oneTimeWorkRequest
    ).enqueue()
}

Однако я могу заставить работать журнал и тост.

Answer 1

Я получил его после добавления open в класс.

open class CustomWorker(
val
context: Context, workerParams: WorkerParameters
) : Worker(context, workerParams) 

Звук немного странный, но теперь все работает нормально.
