This is for an ArcGISFeatureLayer that was initialized using a layer definition and feature set rather than a URL, and I think something must have changed with the way queries work in the new API. In the previous API version the following code worked as expected. I have a feature layer with a few hundred graphics, and I'm trying to query one based on an ObjectID. The following code returns a null feature set even though a graphic with the ObjectID value exists. Query query = new Query(); query.setWhere("OBJECTID = 1"); In fact, it looks like ANY where clause returns a null feature set. Even "1 = 1". If I set the geometry in addition to the where clause, I get all 400 graphics returned and the where clause is ignored. Query query = new Query(); query.setWhere("OBJECTID = 1"); query.setGeometry(mapView.getExtent()); If I loop through the features I can find the one with the ObjectID that I want, and that will be my workaround for now, but I don't understand while simply using setWhere() no longer works and why the where clause is ignored when setGeometry() is used. ...

Recently I ran into two problems which seem to be limitations of the currently implementation of the ArcGIS Runtime SDK for Android, and so I thought I'd post this to let others know of a potential workaround. Problems: I need an offline solution so I created a tpk of the imagery, but it's almost 25 GB and the SDK doesn't seem to read tpk files > 2GB. If I create multiple tpks that are each less than 2GB, the MapView extent gets locked to the extent of the first tpk and I can't pan to the others. By creating several smaller tpks for my area of interest, I ended up with 8 tpks that only total 10 GB (ranging from 1.1 GB to 1.6 GB in size). The good news is that the SDK reads all of them just fine, and it also saves a lot total space since the tpks are all rectangular (envelope) extents, and the single tpk included large areas that I don't care about. However, I experienced the problem that I described above, whereby the MapView would initialize to the extent of the first tpk, and while I could see the edges of the adjacent tpks, I couldn't actually pan the MapView to see them all. Calling mapView.setExtent() didn't solve my problem, and neither did setting 'initExtent' in my layout.xml where I defined my MapView. My solution? Before I loaded the tpks I added an empty ArcGISFeatureLayer as the first layer in my MapView, with a service definition that specifies an extent which covers all of my tpks. The code I used (which uses the Tennessee State Plane project and encompasses the Memphis area) is below. Based on my testing, your feature definition can omit all properties except for the extent. In MyApplication/res/values/config.xml: <string name="config.fullextent.definition"> { \"extent\": {     \"xmin\": 745209,     \"ymin\": 258815,     \"xmax\": 889493,     \"ymax\": 413469,     \"spatialReference\": {         \"wkid\": 102736,         \"latestWkid\": 2274     } } } </string> In MyApplication/src/myPackage/myActivity.java: // add layer to control the overall extent mMapView.addLayer(new ArcGISFeatureLayer(getResources().getString(R.string.config_fullextent_definition), new FeatureSet(), new Options())); // add imagery layers String[] imageryFiles = getResources().getStringArray(R.array.config_imagery_layers); for (String imageryFile : imageryFiles) { mMapView.addLayer(new ArcGISLocalTiledLayer(String.format("file://%s%s", Environment.getExternalStorageDirectory(), imageryFile))); } ...

I was writing a program where I needed to check properties of various fields, and so I decided to use the ArcGISFeatureLayer.getField(String fieldName) but kept experiencing errors. The return value was always null. So as a quick test, I did this... final ArcGISFeatureLayer testLayer = new ArcGISFeatureLayer(     "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Petroleum/KSFields/FeatureServer/0",     MODE.SNAPSHOT);         testLayer.setOnStatusChangedListener(new OnStatusChangedListener() {     private static final long serialVersionUID = 1L;     public void onStatusChanged(Object arg0, STATUS arg1) {         if (arg1 == STATUS.INITIALIZED) {             Field[] fields = testLayer.getFields();             Log.d(TAG, featureLayer.getName() + ": found " + fields.length + " fields");             boolean found = false;             for (Field field : fields) {                 if (testLayer.getField(field.getName()) != null) {                     Log.d(TAG, featureLayer.getName() + ": found field object for " + field.getName());                     found = true;                 }             }             if (!found) {                 Log.d(TAG, featureLayer.getName() + ": no field objects found by name");             }         }     } }); Which results in !! Current Kansas Field Production: found 23 fields !! Current Kansas Field Production: no field object found by name Why does getField(fieldName) always return null? ... View more

I'm trying to instantiate an ArcGISFeatureLayer using the constructor: public ArcGISFeatureLayer (String layerDefinition, FeatureSet featureCollection, ArcGISFeatureLayer.Options layerOption) My layer definition is a string resource (in JSON format) and the feature set is the result of a query that contains a few graphics. The map view, layer definition, and feature set all have the same spatial reference (102100), however I keep getting an error that my feature set needs to be projected. The full error is: E/ArcGIS(2057): Failed to initialize the ArcGISFeatureLayer. E/ArcGIS(2057): java.lang.UnsupportedOperationException: The Feature collection need to be projected. E/ArcGIS(2057):  at com.esri.android.map.ags.ArcGISFeatureLayer.initLayer(Unknown Source) E/ArcGIS(2057):  at com.esri.android.map.ags.ArcGISFeatureLayer$1.run(Unknown Source) E/ArcGIS(2057):  at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:390) E/ArcGIS(2057):  at java.util.concurrent.FutureTask.run(FutureTask.java:234) E/ArcGIS(2057):  at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) E/ArcGIS(2057):  at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) E/ArcGIS(2057):  at java.lang.Thread.run(Thread.java:856) Oddly enough, it works if I use an empty FeatureSet and then add graphics from my existing FeatureSet. In summary, this throws an error: offlineLayer = new ArcGISFeatureLayer(layerDef, featureSet, new Options()); While this works: offlineLayer = new ArcGISFeatureLayer(layerDef, new FeatureSet(), new Options()); offlineLayer.addGraphics(featureSet.getGraphics()); Is this a bug? It's easy enough to work around, I just don't understand why the first line throws an error.

I'm just curious if there are any plans in the near future for REST support for dot density symbology. Right now if I load a service with dot density symbology, the legend will show the same symbol for all categories rather than the actual unique symbols (using the Silverlight API). I haven't found any information about this in the REST forums, and the only thing I found in the Silverlight forum indicated that this was a limitation of the REST API. ... View more

I am in the process of setting up an environment where there will be two web adaptors behind a load balancer to serve a high-availability site. The configuration looks something like this: [ATTACH=CONFIG]20023[/ATTACH] Essentially, two physically separate ArcGIS Server sites are mirrored and attached with a NLB on the front end. Each site serves the same secured services and are configured to use the same shared key for token generation. In this scenario, ideally when the client logs in (authenticating against the built-in store) a token will be generated which will be recognized by both server sites. Is this possible? If so, what needs to be done for this to happen? I know we can adjust the affinity settings on the NLB to prevent requests from the same client from being distributed across the two sites, but the goal is complete failover. Thanks. ... View more

I have a Python script that which creates a database connection using arcpy.CreateDatabaseConnection_management(), and while the connection is created it ignores the version that is passed in as a parameter. The version is valid and the function does not return an error. In order to verify that the parameters were being passed appropriately, I even went so far as to edit the method management.py to print the parameters immediately before it calls: retval = convertArcObjectToPythonObject(gp.CreateDatabaseConnection_management(*gp_fixargs((out_folder_path, out_name, database_platform, instance, account_authentication, username, password, save_user_pass, database, schema, version_type, version, date), True))) In my code, I call: arcpy.CreateDatabaseConnection_management(folderName, fileName, "SQL_SERVER", instance, "OPERATING_SYSTEM_AUTH", None, None, "SAVE_USERNAME", dbName, None, "TRANSACTIONAL", "DBO.test", None) print "Version now set to " + arcpy.Describe(folderName + "/" + fileName).connectionProperties.version In the attached screenshot the variables have been printed out in management.py immediately before creating the connection.  Afterwards, you can see that while the version should be "DBO.test" it is instead "sde.DEFAULT". How can I use Python to create a SQL Server database connection using Operating System authentication with a transactional version name? ... View more
