Project Configuration - AndroidManifest.xml

Performance and the UI Thread
•
All UI work must be done on UI thread!
•
AsyncTask – runs in other threads
•
Handler() – bound to creation thread
•
View.runonUiThread(new runnable(){…})
•
ExecutorService – manage multiple AsyncTasks
•
Threads
The main mapping component - MapView class
public class HelloWorld extends Activity { MapView map = null; /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); map = (MapView) findViewById(R.id.map); } }

Adding map layers
map = new MapView(this); map.addLayer(new ArcGISTiledMapServiceLayer( "http://services.arcgisonline.com/ArcGIS/rest/services/...”)); setContentView(map);
Adding map layers Tiled Map Service map = new MapView(this); map.addLayer(new ArcGISTiledMapServiceLayer( "http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer")); setContentView(map);
Dynamic Map Service map.addLayer(new ArcGISDynamicMapServiceLayer( "http://.../ArcGIS/rest/services/Demographics/ESRI_Population_World/MapServer"));
Feature Service map.addLayer(new ArcGISFeatureLayer(url,MODE.SNAPSHOT));
Image Service map.addLayer(new ArcGISImageServicesLayer(url, null));

Listening for Layer events
tiledLayer.setOnStatusChangedListener(new OnStatusChangedListener() { private static final long serialVersionUID = 1L; public void onStatusChanged(Object source, STATUS status) { if (OnStatusChangedListener.STATUS.INITIALIZED == status && source == tiledLayer) { //TODO } if (OnStatusChangedListener.STATUS.INITIALIZATION_FAILED == status && source == tiledLayer){ //TODO } } }

Map touch events - MapOnTouchListener
Listening for map touch events class MyTouchListener extends MapOnTouchListener { Graphic g; // first point clicked on the map Point p0 = null; int uid = -1; public MyTouchListener(Context arg0, MapView arg1) { super(arg0, arg1); } public boolean onDragPointerMove(MotionEvent from, MotionEvent to) { if (uid == -1) { // first time //TODO } else { //TODO } return true; } ... }
Switching between touch listeners /** * Sets the DEFAULT MapOnTouchListener */ public void setDefaultTouchListener(){ MapOnTouchListener ml = new MapOnTouchListener(getContext(), _mapView); _mapView.setOnTouchListener(ml); } /** * Set the MyTouchListener which overrides various user touch events. */ public void setDrawTouchListener(){ _myTouchListener = new MyTouchListener(getContext(), _mapView); _mapView.setOnTouchListener(_myTouchListener); }
/** * Remove DEFAULT MapOnTouchListener */
map.setOnSingleTapListener(null);

GPS and Device Location
MapView mv = _mapView; _locationService = _mapView.getLocationService(); _locationService.setAutoPan(true); _locationService.setLocationListener(new LocationListener() { //TODO }); _locationService.start();
GPS/Location restart
•
After application cold start, paused, view change.
•
Step 1: Map + layer(s) MUST be loaded first
•
Step 2: Start the GPS and/or LocationService
•
Step 3: autoCenter and/or draw GPS graphic
Restart LocationService #1 – easy way
map.setOnStatusChangedListener(new OnStatusChangedListener() { public void onStatusChanged(Object source, STATUS status) { if (source == map && status == STATUS.INITIALIZED) { LocationService ls = map.getLocationService(); ls.setAutoPan(false); ls.setLocationListener(new LocationListener() { public void onLocationChanged(Location loc) { //TODO } } } } }
Restart LocationService #2 - more control
In onResume() use a perpetual Handler… Step 1: unpause() map Step 2: Implement two nested handlers inside a Runnable Step 3: Implement a counter Step 4: Implement if count > X then fail gracefully Step 5: start the Runnable

Tasks •
All ArcGIS Tasks are AsyncTask -
Geocode
-
GeoProcessing
-
Identify
-
Query
Geoprocessing Example – Step 1
class ViewShedQuery extends AsyncTask { GPParameter[] outParams = null; @Override protected void onPostExecute(GPParameter[] result) { //TODO } @Override protected GPParameter[] doInBackground( ArrayList... params1) { //TODO } }
Geoprocessing Example – Step 2
GPFeatureRecordSetLayer gpf = new GPFeatureRecordSetLayer(“xyz"); gpf.setSpatialReference(map.getSpatialReference()); gpf.setGeometryType(Geometry.Type.Point); // 1st input parameter - Add the point selected by the user Graphic f = new Graphic(mappoint,new SimpleMarkerSymbol(...)); gpf.addGraphic(f); // Second input parameter GPLinearUnit gpl = new GPLinearUnit("Viewshed_Distance"); gpl.setUnits("esriMeters"); gpl.setDistance(8046.72); // Add params params = new ArrayList(); params.add(gpf); params.add(gpl); new ViewShedQuery().execute(params);
Geoprocessing Example – Step 3
@Override protected GPParameter[] doInBackground( ArrayList... params1) { gp = new Geoprocessor(_gpEndPoint); gp.setOutSR(map.getSpatialReference()); try { GPResultResource rr = gp.execute(params1[0]); outParams = rr.getOutputParameters(); } catch (Exception e) { e.printStackTrace(); } return outParams; }
Geoprocessing Example – Step 4 @Override protected void onPostExecute(GPParameter[] result) { if (outParams == null) return; for (int i = 0; i < outParams.length; i++) { if (outParams[i] instanceof GPFeatureRecordSetLayer) { GPFeatureRecordSetLayer fsl = (GPFeatureRecordSetLayer) outParams[i]; for (Graphic feature : fsl.getGraphics()) { Graphic g = new Graphic(feature.getGeometry(), new SimpleFillSymbol(Color.CYAN) ); gLayer.addGraphic(g); } } } }

-
Tile Package (*.tpk)
-
JSON FeatureSet
baseMapLayer = new ArcGISLocalTiledLayer( “file:///mnt/sdcard/ArcGIS/samples/cljf/”+ “OfflineData/ImageryTPK.tpk”);
Offline capabilities •
•

Feature set [array of features]
-
Layer definition (JSON from feature service)

Write to/from disk in JSON
•
Add/remove graphics

Advanced Symbology
Offline – create FeatureLayer
<string name="config.windturbine.layer.definition"> {\"currentVersion\":10.01,\"id\":0,\"name\":\"WindTurbine\”…
//Java classturbinesFeatureLayer = new ArcGISFeatureLayer( R.string.config.windturbine.layer.definition, FeatureSet, null);
Offline – Add/edit features
featureLayer.addGraphics(graphics); //or Graphic[] graphics = new Graphic[ g ]; featureLayer.applyEdits( //adds graphics, //updates, //deletes );
Offline – write JSON to SD Card windTurbine.queryFeatures(query, new CallbackListener() { // create json from resulting FeatureSet @Override public void onCallback(FeatureSet result) { if(result != null){ FileOutputStream outstream = null; try { // create feature set as json string String fsstring = FeatureSet.toJson(result); // create fully qualified path for json file path = createJsonFile(); // create a File from json fully qualified path File outfile = new File(path); // create output stream to write to json file outstream = new FileOutputStream(outfile); outstream.write(fsstring.getBytes()); outstream.close(); } catch (Exception e) { //TODO } } }}); }
Offline – read JSON from SD Card
//Use Jackson JsonParser JsonFactory factory = new JsonFactory(); JsonParser parser = factory.createJsonParser( new FileInputStream(path) ); parser.nextToken(); fs = FeatureSet.fromJson(parser);
