Android Implement LifecycleOwner for WorkManager

WorkManager runs in background thread, while LifecycleOwner/LiveData require main/ui thread, thus it is highly not recommended.

If you really must ...

The sample below utilize CoroutineWorker

class ReminderWorker(appContext: Context, workerParams: WorkerParameters): CoroutineWorker(appContext, workerParams), LifecycleOwner {    companion object {        fun run() : LiveData<WorkInfo> {            val work = OneTimeWorkRequestBuilder<ReminderWorker>().build()            WorkManager.getInstance().enqueue(work)            return WorkManager.getInstance().getWorkInfoByIdLiveData(        }    }    private lateinit var lifecycleRegistry: LifecycleRegistry    override fun getLifecycle(): Lifecycle {        return lifecycleRegistry    }    override suspend fun doWork(): Result = coroutineScope {        val worker = this@ReminderWorker        lifecycleRegistry = LifecycleRegistry(worker)        lifecycleRegistry.currentState = Lifecycle.State.CREATED        val lifecyclerOwner = work        // test if Lifecycle.Event.ON_DESTROY is called        lifecycle.addObserver(object : LifecycleObserver {            @OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)            fun onDestroy() {                Timber.d("onDestroy")            }        })        lifecycleRegistry.currentState = Lifecycle.State.STARTED        // do something        lifecycleRegistry.currentState = Lifecycle.State.DESTROYED        Result.success()    }}
