I guess that didn't happen because the release notes still list it as a known issue. BUG-000115165 Poor WebTiledLayer performance when deriving the class from a custom ServiceImageTiledLayer. ... View more

I've done everything you have asked and this is still the result. In the code, i can debug and see that one MobileBaseMapLayer is added to the basemap and four feature layers are added to the operational layers. But none of that helps because I see absolutely nothing on screen. Not even a grid. No basemap, no feature layers. Nothing. This is with your very own Yellowstone.mmpk example. Here is the code. /* Copyright 2016 Esri * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * *    http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * */ package com.esri.arcgisruntime.sample.openmobilemappackage;

It occurs in Android 6-9 I do not have simple code to reproduce it. It does not happen all the time, but happens fairly often for actual users. If I knew what triggers it, I'd be closer to fixing it. This code is in onCreate() of the activity. mMapView.addMapScaleChangedListener(new MapScaleChangedListener() {     @Override     public void mapScaleChanged(MapScaleChangedEvent mapScaleChangedEvent) {         updateZoomLevelText();     } }); This code is in a local method. Only important thing here is that we are calling getMapScale. private void updateZoomLevelText() {     tvZoomLevel.setText(String.valueOf(BC_Helper.getZoomLevelByScale(mMapView.getMapScale()))); } Only thing that occurs to me is that somehow we are getting this event at a point in the Activity lifecycle where the activity, and therefore the MapView, is no longer valid. ...

Thanks. I'd hate to have to resort to proxies or something to work around the Url pattern limitations of WebTiledLayer and the performance limitations of the ServiceImageTiledLayer. ... View more

As a slight correction. WebTiledlayer does not allow you to overrride getTileUrl and expect it to be called. We are using a subclass of ServiceImageTiledLayer. I have produced a simple example using your WebTiledLayer sample. The If you change this line of code to use WebTiledLayer instead of my custom class, performance is just fine. Using my custom class inherited from ServiceImageTiledLayer  - well, I am still waiting for the map to refresh after 10 minutes. In addition, the runtime thread pool of ArcGIS gets all used up, so features like place search suggestion don't work. final MyWebTiledLayer webTiledLayer= new MyWebTiledLayer(templateUri); I have escalated the case with Esri support, but they are unlikely to find a solution without help from developers. While this template could be used with either WebTiledLayer or a custom class, there are many that cannot. We use up to 60 template urls in our application. Web Tiled Layer can only handle {row} {col} {level} as tags. Notably it cannot handle TMS server, just because the y is upside down from your {row} tag. It cannot handle quadkeys like in Bing Urls. I am aware there is a Bing Maps layer, but it only has three styles. It could not handle, for instance, the Ordnance Survey style for the UK. It can't handle a bounding box query to create tiles from a WMS server that supports 900913 projection. /* Copyright 2017 Esri * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * *    http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * */ package com.esri.arcgisruntime.sample.webtiledlayer; import java.util.Arrays; import java.util.List; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import com.esri.arcgisruntime.arcgisservices.TileInfo; import com.esri.arcgisruntime.layers.WebTiledLayer; import com.esri.arcgisruntime.loadable.LoadStatus; import com.esri.arcgisruntime.mapping.ArcGISMap; import com.esri.arcgisruntime.mapping.Basemap; import com.esri.arcgisruntime.mapping.Viewpoint; import com.esri.arcgisruntime.mapping.view.MapView; public class MainActivity extends AppCompatActivity {   private MapView mMapView;   @Override   protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     // access MapView from layout     mMapView = (MapView) findViewById(R.id.mapView);     // list of subdomains     List<String> subDomains = Arrays.asList("a", "b", "c", "d");     // url pattern     String templateUri = "http://services.thelist.tas.gov.au/arcgis/rest/services/Basemaps/Topographic/ImageServer/tile/{level}/{row}/{col}/";     // webtile layer     final MyWebTiledLayer webTiledLayer= new MyWebTiledLayer(templateUri);     webTiledLayer.loadAsync();     webTiledLayer.addDoneLoadingListener(new Runnable() {       @Override       public void run() {         if (webTiledLayer.getLoadStatus() == LoadStatus.LOADED) {           // use webtile layer as Basemap           ArcGISMap map = new ArcGISMap(new Basemap(webTiledLayer));           map.setInitialViewpoint(new Viewpoint(-42.106967,147.097578,577791));           mMapView.setMap(map);           TileInfo tinfo = webTiledLayer.getTileInfo();           Log.i("webtiledlayer","web tileinfo: " + tinfo);           // custom attributes           /*           webTiledLayer.setAttribution("Map tiles by <a href=\"http://stamen.com/\">Stamen Design</a>, " +               "under <a href=\"http://creativecommons.org/licenses/by/3.0\">CC BY 3.0</a>.
