Fixed version (ground truth):

  for (  final String photoPath : photoPaths) {
    queue.addOperation(new Runnable(){

        File file=new File(photoPath);
        NSData imageData=NSData.read(file);
        CGDataProvider dataProvider=CGDataProvider.create(imageData);
        CGImageSource imageSource=CGImageSource.create(dataProvider,null);
        CGImageProperties imageProperties=imageSource.getProperties(0,null);
        CGImagePropertyGPSData gpsInfo=imageProperties.getGPSData();
        if (gpsInfo != null) {
          CLLocationCoordinate2D coord=new CLLocationCoordinate2D();
          coord.setLatitude(gpsInfo.getNumber(CGImagePropertyGPS.Latitude));
          coord.setLongitude(gpsInfo.getNumber(CGImagePropertyGPS.Longitude));

          }
          if (gpsInfo.getString(CGImagePropertyGPS.LongitudeRef).equals("String_Node_Str")) {
