This should explain projections: Spatial references—ArcGIS Runtime SDK for Android | ArcGIS for Developers Mapping Projections Explained​ Additionally, what code are you using to zoom to the extent?  It is possible that if you are zooming to -38, 71, that you will be zoomed into the center of the map because the map projections unit of measurement would then be in meters, not decimal degrees as you may expect. ...

Are you waiting for the map to be fully initialized? mapView.setOnStatusChangedListener(new OnStatusChangedListener() {   @Override public void onStatusChanged(Object o, STATUS status) {    if (status == STATUS.INITIALIZED) {    //Do Something    }   } }); Additionally, are you placing your coordinates in web mercator projection? ...

Mohamed EzzerI​ What I would do, if working with only one layer, is use the getFullExtent() method on that layer and then use mapView.setExtent to then set the extent that I would like to zoom to.  This of course would all have to occur after the layer is fully initialized. Layer.GetFullExtent() Layer | ArcGIS Android 10.2.8 API MapView.SetExtent() MapView | ArcGIS Android 10.2.8 API I hope this helps! ... View more

double[][] p = new double[pointsArray.length()][2]; The points array would be the outside array which would contain the amount of points.  I believe that you have this backwards.  As well as this: p[pointCount][0] = Double.parseDouble(point.getString("latitude")); p[pointCount][1] = Double.parseDouble(point.getString("longitude")); ...

Hello Mohamed EzzerI​, I was able to get the feature to draw in Casablanca using the following snippet: package com.arcgis.androidsupportcases.addpolygongraphic; import android.graphics.Color; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import com.esri.android.map.MapView; import com.esri.android.map.event.OnStatusChangedListener; import com.esri.android.toolkit.map.MapViewHelper; public class MainActivity extends AppCompatActivity {   MapView mapView;   @Override protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    mapView = (MapView) findViewById(R.id.map);    mapView.setOnStatusChangedListener(new OnStatusChangedListener() {    @Override public void onStatusChanged(Object o, STATUS status) {    if (status == STATUS.INITIALIZED) {   MapViewHelper mapViewHelper = new MapViewHelper(mapView);   double[][] latLon = new double[][] {{    33.599389, -7.610728    },    {    33.599985, -7.597180    },    {    33.588879, -7.617027    }   };   int graphic = mapViewHelper.addPolygonGraphic(latLon,"pol_t", "pol_st", "", Color.GREEN, Color.DKGRAY,2, 0);    Log.e("NOHE", "" + graphic);    }   }   });   } } Here is the screenshot of my end result: ...
