Geometries are immutable so you can't move them.  Instead you just create a new one and its very easy to apply a new geometry to an existing graphic and hence move it. I've had a go at this using a point and a polygon which I've also created with ellipseGeodesic.  It looked like this: My app had some class members to track my ship private GraphicsOverlay dynamicGraphicsLayer; private double xPos=0, yPos=0; // current location of my ship private Graphic shipGraphic; // graphic for ship private Graphic shipBufferGraphic; // graphic for buffer around ship A method to create my buffer / ellipse public Polygon generateBuffer(Point shipPosition) { Polygon buffer = null; GeodesicEllipseParameters parameters = new GeodesicEllipseParameters(); parameters.setCenter(shipPosition); parameters.setSemiAxis1Length(500); parameters.setSemiAxis2Length(500); parameters.setMaxSegmentLength(5); buffer = (Polygon) GeometryEngine.ellipseGeodesic(parameters); return buffer; } The initial position was drawn like this: // create a dynamic graphics layer dynamicGraphicsLayer = new GraphicsOverlay(GraphicsOverlay.RenderingMode.DYNAMIC); mapView.getGraphicsOverlays().add(dynamicGraphicsLayer); // symbols SimpleLineSymbol bufferSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, 0xFF00FF00, 3); SimpleMarkerSymbol shipSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.Style.CIRCLE, 0xFFFF0000, 10); // geometries Point shipPosition = new Point(xPos,yPos, SpatialReferences.getWebMercator()); Polygon shipBuffer = generateBuffer(shipPosition); // initial graphics showing ship and buffer shipGraphic = new Graphic(shipPosition, shipSymbol); shipBufferGraphic = new Graphic(shipBuffer, bufferSymbol); // adding graphics to graphics layer dynamicGraphicsLayer.getGraphics().add(shipGraphic); dynamicGraphicsLayer.getGraphics().add(shipBufferGraphic); Then I had a button on my app to move the position of the ship slightly Button addGraphics = new Button("move ship"); addGraphics.setOnAction(event -> { // move the ship xPos = xPos + 50; yPos = yPos + 50; Point newLocation = new Point(xPos, yPos, SpatialReferences.getWebMercator()); // update the graphics location moveShip(newLocation); }); Which in turn calls this simple code to apply the new geometries to your existing graphics public void moveShip(Point newLocation) { shipGraphic.setGeometry(newLocation); shipBufferGraphic.setGeometry(generateBuffer(newLocation)); } This is a very common workflow and even if you use it for updating thousands of graphics it works well.

The OpenGL Context creation issue was fixed in 100.9 so you need to get to the reason why this is not working for you.  Have you switched to using AndroidX?   Have you tried running a simple sample like this to see if the API works on your device? arcgis-runtime-samples-android/java/display-map at master · Esri/arcgis-runtime-samples-android · GitHub  It is best that you continue this conversation on the other thread or create a new one and we will help you.  The only answer to the context creation issue is to use 100.9. ...

Can you tell me what version of the SDK you are using?  I'm aware of this issue in earlier versions, but I do believe this was fixed in 100.9...  however if you can tell me the version you are experiencing this and the full details of the device this will help. ... View more

There are a couple of approaches you could take to this.  One way would be to use Local Server to run a geoprocessing tool to create it for you.  I can see that fishnet is supported here Local Server geoprocessing tools support—ArcGIS Runtime SDK for Java | ArcGIS for Developers  If you didn't want to follow the Local Server / Geoprocessing approach, it wouldn't be hard to to take the bounding box of your geometry and write some of your own code to create a fishnet.  You could display this in a graphic layer. I'm not sure of your workflow or what you need the fishnet for, but do either of these ideas help? ... View more

This isn't something we've seen before and we've not had crash reports like this in any of the apps we deploy to the app store. There is however no escaping the error you are seeing in the log.  Some more information would be helpful to track this down.  Do you have any information of what the tests are doing at the time of the crash? Also some clues about your code would help.  It's pretty obviously happening when you are calling a MapView.getRotation, but can you tell me a little more about the context you are calling this in? Also can you confirm what version of the API you are using? ... View more

Hi Rafael, For the bearing calculation there isn't a method which takes 2 points.  I can however see the value in it so we may consider if for a future release. In the meantime my method should work, but the calculation will only be correct for project coordinate systems and over small distances to be accurate.   Glad this helped. Mark ... View more

I'm looking at for format of you license code and I'm not sure these is complete  I appreciate you've sensibly replaced numbers with "*", but is this all you were given? Can you tell me where you got the code from? Can you also confirm what version of the product you are using? ... View more

I'm happy to help but you'll need to give me some clues about what is happening and what your code looks like. Can you share any code and a stack trace? What device are you running on?  Emulator or physical? What data are you using and what is your app doing? I also noticed an error in my original reply.  I said that 100.8 was out latest release whereas its 100.9.  However this shouldn't make any difference. There are lots of sample apps which you can try out which might show you how to get going here written in Kotlin and Java. This is a good starter app : arcgis-runtime-samples-android/kotlin/display-map at master · Esri/arcgis-runtime-samples-android · GitHub  There is a Java equivalent there too:  arcgis-runtime-samples-android/java/display-map at master · Esri/arcgis-runtime-samples-android · GitHub  ...

That is very curious.  I'd be interested to compare the Kotlin code which doesn't work with the Java code which does.   If you want to share this code, I'd be happy to comment on why the Kotlin code didn't work.   ... View more

Can you share any code or data which would reproduce this issue? I've been running the sample code this morning from this sample code and it is fluid and not flashing.  Does this sample work for you without any issues? ... View more

The stack trace doesn't give me much to go on.  Can you show any code and say what version of the API you are using? Not sure if you are using Kotlin or Java, but here are some samples which may help to explain how to perform geocoding operations. arcgis-runtime-samples-android/java/find-address at master · Esri/arcgis-runtime-samples-android · GitHub  arcgis-runtime-samples-android/java/find-place at master · Esri/arcgis-runtime-samples-android · GitHub  The above samples are Java, but we have the same ones written in Kotlin in the same git repository. Does this help? ... View more

The code in the example I have above explains how to move a graphic.  You just need to create a new geometry and apply it to the existing graphic. // this code section is for moving the graphic to a new location // start by creating a new point Point newPoint = new Point(5000,5000); // apply the new point to the graphic graphic.setGeometry(newPoint); If this isn't what you are trying to achieve, then can you explain exactly what you are trying to implement. ...

The API has changed a little, but once you have understood the new concepts it will work well for you. In your application it sounds like you are maintaining your own locations which you display in your app.  If this is the case then the container you will want to use is a GraphicsOverlay.  I have shown some very simple code below which creates a graphics overlay, adds it to your MapView and adds a graphic.  It then goes on to move the graphic straight away.  Note that the Point class is immutable. // create a graphics overlay GraphicsOverlay graphicsOverlay = new GraphicsOverlay(); mapView.getGraphicsOverlays().add(graphicsOverlay); // make a symbol for your graphic - this is just a dot SimpleMarkerSymbol simpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.Style.CIRCLE, 0xFF00FF00, 10); // make a point geometry - note its immutable. Point initialPoint = new Point(1000,1000); // create your graphic from the symbol and geometry Graphic graphic = new Graphic(initialPoint, simpleMarkerSymbol); // add it to the graphics overlay - this will allow you to see the point graphicsOverlay.getGraphics().add(graphic); // this code section is for moving the graphic to a new location // start by creating a new point Point newPoint = new Point(5000,5000); // apply the new point to the graphic graphic.setGeometry(newPoint); // your graphic is now in the new location! There is lots of documentation explaining how this work here:  Add graphics and text to graphics overlays—ArcGIS Runtime SDK for Android | ArcGIS for Developers  There are also samples in gitHub.  arcgis-runtime-samples-android/java at master · Esri/arcgis-runtime-samples-android · GitHub  (Kotlin examples are there too if you prefer). There is an example of a 3D app which shows how to rapidly update graphics which you can take a look at: arcgis-runtime-samples-android/java/animate-3d-graphic at master · Esri/arcgis-runtime-samples-android · GitHub  Does this help? ...

10.2.9 is a very old release which is no longer supported or in development. The current release of ArcGIS Runtime is 100.9.  Have you tried your layer in this version? If you want to try it out, there is a github repository with lots of samples showing how to implement various use-cases.  This sample may be of interest to you: arcgis-runtime-samples-android/kotlin/display-kml at master · Esri/arcgis-runtime-samples-android · GitHub  ...
