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. Could not update the active symbol
java.lang.RuntimeException: Invalid SpatialReference.
