Flex API 2.0 with Air Android API 2.5

AlpineTech — Tue, 21 Sep 2010 03:25:05 GMT

I am testing the Flex API 2.0 to see if I can get it to run with latest pre-release of the Air Android 2.5 SDK (AIR25_win_sdk_20100909.zip). Using Flex Builder 4 I created an Air Desktop app and added a reference to the ArcGIS Flex API 2.0 library. First, I tried one of the simple sample applications that just shows a tiled map from ArcGIS online, nothing fancy. It built, but did not run. It threw an error, but I expected that because the Air Android SDK does not support .mxml files yet. Second, I tried the same thing with a simple action script no .mxml file. I thought that might work, but it threw an error when I ran it. The error says:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.esri.ags::Map()
at FlexMobileGIS1()

Please see the action script below and let me know if there is something I am missing here?

package
{
import com.esri.ags.Map;
import com.esri.ags.layers.ArcGISTiledMapServiceLayer;
import com.esri.ags.geometry.Extent;
import flash.display.DisplayObject;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.Event;
import flash.system.*;

public class FlexMobileGIS1 extends Sprite
{

public function FlexMobileGIS1()
{
   stage.scaleMode = flash.display.StageScaleMode.NO_SCALE;
   stage.align = StageAlign.TOP_LEFT;
   var map:Map = new Map();
   var extent:Extent = new Extent(-13635000,4541000,-13625000,4547000);
   extent.spatialReference.wkid = 102100;
   map.extent = extent;
   var tiledLyr:ArcGISTiledMapServiceLayer = new ArcGISTiledMapServiceLayer();
   tiledLyr.url = "http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer";
   map.addLayer(tiledLyr);
   stage.addChild(map);
}
}
}

This is/was a bug that will be fixed in version 2.1 of the Flex API.

I tried the new ArcGIS Flex 2.1 API, and yes my first error did not occur, but still no go. I suspect it might be because the API still depends on mx.styles.StyleManager (and other mx stuff). I found this information that indicates that a bunch of the mx stuff was depreciated for Air:

http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/deprecated.html

What now?

This is the ERROR:

It works! I tried another approach with an mxml. I'll write up something later and post it.
