Could not update the active symbol - Using SVY21 Spatial Reference

RamKola — Tue, 05 Mar 2013 06:14:04 GMT

We are trying to use ESRI Android SDK 2.0 with OneMap server based in Singapore. (It uses SVY21 spatial reference). I am able to display the Map on the screen but I keep getting - "Could not update the active symbol java.lang.RuntimeException: Invalid SpatialReference."

I have tried several approaches including creating the MapView via Java and adding to the Layout. The other approach using XML is shown below. I will be grateful if any expert can point me in the right direction.

Hi,

I am also facing same issue. Have you got this issue resolved?

Thanks.

I couldn't find a solution till date. I am inclined to think that it needs some small piece of code that we are missing.
It would be great if anyone from ArcGIS could give us a suggestion.

I do see a few apps in the Android store - Pocket OneMap which are successfully using OneMap as the base-map.

cheers
Ram

am also getting the same issue here,when i pinch the for zoomin or zoomout these exceptions raised
i couldn't find the solution.
plz help me if any expert has the solution for this.

I think this is not the problem with ArcGis. This is bcz of the problem with OneMap. If you use
http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer
then it will work perfectly.

One more chance is the SpatialReference of OneMap is not available in ArcGis list.

If you add

locationService.setAccuracyCircleOn(false);

before you start the location service it will work.

I'm also encountering the same issue. Any update on this one? Thanks.
