Hi Zijian,
Yes, you can use Feature Service to support editing functionalities while using the Map Service to display the label as per my previous suggestion from Method 1, that is, author the map with proper labelling. Whenever a geometry's attribute is added/updated through the Feature Service, the Map Server will be able to render new map images with the updated information.
For this to happen, you cannot use a TileMapServiceLayer which lets you to work with a cached map service resource exposed by the ArcGIS Server REST API. A cached service accesses tiles from a cache instead of dynamically rendering images. For dynamic map services, see https://developers.arcgis.com/android/api-reference/reference/com/esri/android/map/DynamicLayer.html.
Let me know if I understood you correctly.
Cheers,
Raymond
Hi Raymond,Your suggestion is really helpful, now I want to use ArcGISDynamicMapServiceLayer to display the label info, but the problem is how I can only display the label info without the symbols. This is my code.This is the map service
DynamicLayer li = new ArcGISDynamicMapServiceLayer(this.getResources()
.getString(R.string.feature_url));
mMapView.addLayer(li);

I can display neither symbol nor label info. That is really strange. When I use the featureLayer, I can at least display symbols.Thanks for your help.Cheers Zijian
