Cant get Geopoints to add to google map due to; Couldn't get connection factory client

Question

I am getting this error while try to plot multiple Geopoint locations onto a google map. I am reading the latitude and longitude from a MySQL database through PHP and JSON. I have looked at the main examples, such as Couldn't get connection factory client, Couldn't get connection factory client - fighting with Google Maps, Android MapActivity : Couldn't get connection factory client.
I can confirm it is not an invalid API key as I have generated 2 different keys and returned the same error. It is also not an API level problem either, I tried to run the application on API level 17 and on level 8 and still no joy. When I run the code it displays the map no problem and then gets to my exception toast message of "Error displaying contents"
Here is my mapview.java code:

import java.util.ArrayList;

    try 
    {

         HttpClient httpclient = new DefaultHttpClient();

         //httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
         HttpResponse response = httpclient.execute(httppost);
         HttpEntity entity = response.getEntity();
         is = entity.getContent();

    }

    catch(Exception e)

    }


        try{        


        jarray = new JSONArray("$json_output[]");
        JSONObject json_data = null;
                for(int i = 0; i < jarray.length(); i++)
                {
                    json_data = jarray.getJSONObject(i);

                    LAT=json_data.getDouble("lat");
                    LNG=json_data.getDouble("lng");

                    GeoPoint point = new GeoPoint((int)(LAT * 1E6), (int)(LNG * 1E6));
                    OverlayItem overlayitem = new OverlayItem(point, "TEXT", null);

                    List<Overlay> mapOverlays = mapview.getOverlays();
                    Drawable drawable = this.getResources().getDrawable(R.drawable.marker);
                    myItemizedOverlay itemizedoverlay = new myItemizedOverlay(drawable, this);

                    MapController mapController = mapview.getController();

                    //mapController.animateTo(point);
                    mapController.setZoom(8);

                    itemizedoverlay.addOverlay(overlayitem);
                    mapOverlays.add(itemizedoverlay);
                }
            }
            catch(JSONException e1)
            {
            Toast.makeText(getBaseContext(), "Error displaying contents" ,Toast.LENGTH_LONG).show();
            }       
                catch (ParseException e1) 
                {
                e1.printStackTrace();
                }   
    }
    @Override
    protected boolean isRouteDisplayed() 
    {
        return false;
    }
}

This is my ItemizedOverlay.java code:

    import java.util.ArrayList;

    import android.app.AlertDialog;
    import android.content.Context;
    import android.graphics.drawable.Drawable;

    import com.google.android.maps.OverlayItem;
    import com.google.android.maps.ItemizedOverlay;


    public class myItemizedOverlay extends ItemizedOverlay 
    {

        private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>();
        private Context mContext;

        public myItemizedOverlay(Drawable marker, Context context) 
        {
            super(boundCenterBottom(marker));
            mContext = context;

        }

        public void addOverlay(OverlayItem overlay) 
        {
            mapOverlays.add(overlay);
            this.populate();
        }


        @Override
        protected OverlayItem createItem(int i) 
        {
          return mapOverlays.get(i);
        }

        @Override
        public int size() 
        {
            return mapOverlays.size();
        }

        @Override
        protected boolean onTap(int index) 
        {
          OverlayItem item = mapOverlays.get(index);
          AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
          dialog.setTitle(item.getTitle());
          dialog.setMessage(item.getSnippet());
          dialog.show();
          return true;
        }

    }

I would appreciate any help I get, thanks in advance.

If you have generated these keys recently, you will not get your results, because API v1 is deprecated and won't work.

You may want to switch to Maps API v2: https://developers.google.com/maps/documentation/android/

Don't try to use your old code, because new API doesn't share any code with API v1.
