Offline Map doesn't show all layers

Hi,

I'm new to The Esri Community and Android SDK programming. I'm having an issue where I need to offline a section of the map as outlined in this tutorial - https://developers.arcgis.com/android/latest/guide/take-map-offline-on-demand.htm but I'm using inherited code outlined below to do so and the output map doesn't show all of the layers of the maps and throws an exception:

I/System.out: Non Outage Completion cannot be taken offline
Error : com.esri.arcgisruntime.ArcGISRuntimeException: Illegal state: Unable to support duplicate feature layers already exists

I use this code to generate the map and the exception:

fun generateOfflineMap() { // create a progress dialog to show map download progress progressDialog!!.setTitle("Generate Offline Map") progressDialog!!.setMessage("Downloading map...") progressDialog!!.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL) progressDialog!!.isIndeterminate = false progressDialog!!.setCanceledOnTouchOutside(false) progressDialog!!.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel") { dialog, which -> downloadMsg!!.visibility = View.GONE mGraphicsOverlay!!.graphics.clear() mapdownloadJob!!.cancel() //set the flag to false to re-select the download area for consecutive downloads isMapDownloadAreaSelected = false isMapDownloadInProgress = false dialog.dismiss() } if (!isMapDownloadAreaSelected) { downloadMsg!!.visibility = View.VISIBLE // create a graphics overlay for the map view mGraphicsOverlay = GraphicsOverlay() mapView!!.graphicsOverlays.add(mGraphicsOverlay) // create a graphic to show a box around the extent we want to download mDownloadArea = Graphic() mGraphicsOverlay!!.graphics.add(mDownloadArea) val simpleLineSymbol = SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, Color.RED, 2F) mDownloadArea!!.symbol = simpleLineSymbol // upper left corner of the area to take offline minScreenPoint = Point(200, 200) // lower right corner of the downloaded area maxScreenPoint = Point(mapView!!.width - 200, mapView!!.height - 200) // convert screen points to map points minPoint = mapView!!.screenToLocation(minScreenPoint) maxPoint = mapView!!.screenToLocation(maxScreenPoint) // use the points to define and return an envelope if (minPoint != null && maxPoint != null) { val envelope = Envelope(minPoint, maxPoint) mDownloadArea!!.geometry = envelope } //Debugging - use this to get errors with layers and tables var offlineMapTask = OfflineMapTask(map); var minScale = mapView!!.mapScale val maxScale = mapView!!.map.maxScale val generateOfflineMapParameters = GenerateOfflineMapParameters(mDownloadArea!!.geometry, minScale, maxScale) val offlineMapCapabilitiesFuture: ListenableFuture<OfflineMapCapabilities> = offlineMapTask.getOfflineMapCapabilitiesAsync(generateOfflineMapParameters) offlineMapCapabilitiesFuture.addDoneListener { val offlineMapCapabilities: OfflineMapCapabilities = offlineMapCapabilitiesFuture.get() if (offlineMapCapabilities.hasErrors()) { // Handle possible errors with layers for ((key, value) in offlineMapCapabilities.getLayerCapabilities()) { if (!value.isSupportsOffline()) { println(key.getName().toString() + " cannot be taken offline\n" + "Error: " + value.getError()) } } // Handle possible errors with tables for ((key, value) in offlineMapCapabilities.getTableCapabilities()) { if (!value.isSupportsOffline()) { println(key.tableName.toString() + " cannot be taken offline\n" + "Error : " + value.getError()) } } } else { // All layers and tables can be taken offline! showMessage("All layers are good to go!") } } //End Debugging // update the download area box whenever the viewpoint changes mapView!!.addViewpointChangedListener { viewpointChangedEvent: ViewpointChangedEvent? -> if (map!!.loadStatus == LoadStatus.LOADED) { // upper left corner of the area to take offline minScreenPoint = Point(200, 200) // lower right corner of the downloaded area maxScreenPoint = Point(mapView!!.width - 200, mapView!!.height - 200) // convert screen points to map points minPoint = mapView!!.screenToLocation(minScreenPoint) maxPoint = mapView!!.screenToLocation(maxScreenPoint) // use the points to define and return an envelope if (minPoint != null && maxPoint != null) { val envelope = Envelope(minPoint, maxPoint) mDownloadArea!!.geometry = envelope } } } // map download area selected isMapDownloadAreaSelected = true } else { if (!isMapDownloadInProgress) { progressDialog!!.progress = 0 progressDialog!!.show() // delete any offline map already in the cache deleteDirectory(File(offlineMapDirectoryPath)) // specify the extent, min scale, and max scale as parameters var minScale = mapView!!.mapScale val maxScale = mapView!!.map.maxScale // minScale must always be larger than maxScale if (minScale <= maxScale) { minScale = maxScale + 1 } val generateOfflineMapParameters = GenerateOfflineMapParameters(mDownloadArea!!.geometry, minScale, maxScale) // create an offline map offlineMapTask with the map val offlineMapTask = OfflineMapTask(mapView!!.map) // create an offline map job with the download directory path and parameters and start the job mapdownloadJob = offlineMapTask.generateOfflineMap(generateOfflineMapParameters, offlineMapDirectoryPath) isMapDownloadInProgress = true // replace the current map with the result offline map when the job finishes mapdownloadJob.addJobDoneListener(Runnable { if (mapdownloadJob.getStatus() == Job.Status.SUCCEEDED) { val result = mapdownloadJob.getResult() downloadMsg!!.visibility = View.GONE mGraphicsOverlay!!.graphics.clear() //set the flag to false to re-select the download area for consecutive downloads isMapDownloadAreaSelected = false isMapDownloadInProgress = false //show the map mapView!!.map = result.offlineMap //hide save map, show cancel map //save_map.visibility = View.GONE //cancel_map.visibility = View.VISIBLE //hide the legend - it must be online legendHeader!!.visibility = View.GONE if (mAttributes != null) { sharedPreferencesPseg.setString("ESDNUMBERFORSAVEDMAP", mAttributes!!.cadjobno) } else { sharedPreferencesPseg.setString("ESDNUMBERFORSAVEDMAP", "MAINTAB") } Toast.makeText(requireContext(), "Map downloaded successfully", Toast.LENGTH_LONG).show() } else if (mapdownloadJob.getStatus() == Job.Status.FAILED) { Toast.makeText(requireContext(), "Error in generate offline map", Toast.LENGTH_LONG).show() } else if (mapdownloadJob.getStatus() == Job.Status.PAUSED) { Toast.makeText(requireContext(), "Map download cancelled", Toast.LENGTH_LONG).show() } progressDialog!!.dismiss() }) mapdownloadJob.addProgressChangedListener(Runnable { progressDialog!!.progress = mapdownloadJob.getProgress() }) mapdownloadJob.start() } else { mapdownloadJob!!.addProgressChangedListener { progressDialog!!.progress = mapdownloadJob!!.progress } progressDialog!!.show() } } }

When the code to display the map is called the map is displayed but with minimal detail and it appears layer(s) are left out. I'm not sure what is causing this. I also use this function below to open the map and wanted to provide this to see if there are errors in this code as well:

private fun openOfflineMap() { val offlineMapPackage = MobileMapPackage(offlineMapDirectoryPath) offlineMapPackage.loadAsync() offlineMapPackage.addDoneLoadingListener { if (offlineMapPackage.maps.size == 0) { mapNotDownloadedMsg!!.visibility = View.VISIBLE progressBar!!.visibility = View.GONE } else { mapView!!.map = offlineMapPackage.maps[0] callout = mapView!!.callout progressBar!!.visibility = View.GONE // downloadMapIcon.setVisibility(View.GONE); mapView!!.visibility = View.VISIBLE mapView!!.onTouchListener = object : DefaultMapViewOnTouchListener(context, mapView) { override fun onSingleTapConfirmed(e: MotionEvent): Boolean { if (callout.isShowing()) { callout.dismiss() } val screenPoint = Point(Math.round(e.x), Math.round(e.y)) // identifyResult(screenPoint); identifyandDisplayResults(screenPoint) return true } } } } }

Any help you can provide is much appreciated! If there is a need for additional detail please let me know and I will provide as best I can.

Thanks,

John Meah
