I have written a new usecase to communicate to api which uses Flow, I am guessing I am not handing the threading properly in the Usecase between Main thread and IO thread,
This is the error I get
-01-18 02:20:40.555 26602-26870/com.xxx.xx.staging E/AndroidRuntime: FATAL EXCEPTION: DefaultDispatcher-worker-4 Process: com.xxx.xx.staging, PID: 26602 java.lang.IllegalStateException: Event bus [Bus "fill_order"] accessed from non-main thread null at com.squareup.otto.ThreadEnforcer$2.enforce(ThreadEnforcer.java:47) at com.squareup.otto.Bus.post(Bus.java:317) at com.xxx.xx.fragments.filller.fillorder.BasefillOrderFragment.postFldeckStatusUpdateEvent(BasefillOrderFragment.java:117) at com.xxx.xx.fragments.filller.fillorder.fillOrderDataFragment.postFldeckStatusUpdateEvent(fillOrderDataFragment.java:1955) at com.xxx.xx.fragments.filller.fillorder.fillOrderDataFragment.updateView(fillOrderDataFragment.java:845) at com.xx.xx.fragments.filller.fillorder.fillOrderDataFragment.legacyUpdateView(fillOrderDataFragment.java:2317) at com.xxx.xx.clean.fillorder.presenter.BasefillDataPresenter.onStartfilllingSuccess(BasefillDataPresenter.kt:460) at com.xxx.xx.clean.fillorder.presenter.BasefillDataPresenter.handleStartfilllingClicked(BasefillDataPresenter.kt:315) at com.xxx.xx.clean.fillorder.presenter.BasefillDataPresenter.access$handleStartfilllingClicked(BasefillDataPresenter.kt:49)The error is at handleStartfilllingClicked(view, it) in . collect
I am calling startfilllingUseCaseFlow usecase which might be the issue
@FlowPreviewfun initFlowSubscription(view: View) { launch { view.startfilllingObservableFlow .conflate() .catch { onStartfilllingError(view) } .flatMapMerge { if (!hasOpenInopIncidents()) { equipmentProvider.get()?.let { startfilllingUseCaseFlow(StartfilllingUseCaseFlow.Params(it)) }!! } else { val incidentOpenResponse = GenericResponse(false) incidentOpenResponse.error = OPEN_INCIDENTS flowOf(incidentOpenResponse) } } .collect { handleStartfilllingClicked(view, it) // ERROR IS HERE } }}private fun handleStartfilllingClicked(view: View, response: GenericResponse) { if (response.success == false && response.error == OPEN_INCIDENTS) { view.showCannotProceedInopIncidentDialog() view.hideLoader(false) return } onStartfilllingSuccess(view) // Error is here}StartfilllingUseCaseFlow
class StartfilllingUseCaseFlow @Inject constructor( private val currentOrderStorage: CurrentOrderStorage, private val fillOrderRepository: fillOrderRepository, private val app: App): FlowUseCase<StartfilllingUseCaseFlow.Params, GenericResponse>() { override suspend fun run(params: Params): Flow<GenericResponse> { val startTime = DateTime() val action = TimestampedAction( app.session.user.id, null, startTime ) return flowOf(fillOrderRepository.startfilllingSuspend( currentOrderStorage.fillOrder!!.id, action )).onEach { onSuccess(startTime, params.equipment) } .catch { e -> e.message?.let { onError(it) } } .flowOn(Dispatchers.IO) } private fun onSuccess(startTime: DateTime, equipment: Equipment) { if (currentOrderStorage.getfillOrder() == null) return currentOrderStorage.getfillOrder()!!.setStatus(fillOrderData.STATUS_fillLING) equipment.times.start = startTime app.saveState() } private fun onError(errorMessage: String) { Timber.e(errorMessage, "Error calling started fillling! %s", errorMessage) } data class Params(val equipment: Equipment)}I am guessing I am not handing IO and Main thread properly here
abstract class FlowUseCase<in Params, out T>() { abstract suspend fun run(params: Params): Flow<T> suspend operator fun invoke(params: Params): Flow<T> = run(params).flowOn(Dispatchers.IO)}Could you suggest where I am gettig it wrong
ThanksR
