Class Veery

countLocationHistory(int format, Long since, Long unti)

Count Historical data of Geolocations observed during a given period of time.

The format parameter defines the type of data to count

Parameters

Param name	Type	Possible Values / Usage
format	int	Veery.HISTORY_RAW will return the amount of geolocation measured
		HISTORY_ROUTEMATCH will return the amount of trips computed
since	Long	Represent the time of the beginning of the historical period required. Format is the EPOCH in millis as returned by Calendar.getTimeInMillis()
		null could be used for "since the beginning"
until	Long	Represent the time of the end of the historical period required. Format is the EPOCH in millis as returned by Calendar.getTimeInMillis()
		null could be used for "until the end"

Returns

int

• HISTORY_RAW will return the amount of geolocation measured
• HISTORY_ROUTEMATCH will return the amount of trips computed

Usage / Example

The following example prints the geolocation history to a mMap Google Maps object

Calendar calendar = Calendar.getInstance(); // now
Long until = calendar.getTimeInMillis();
calendar.add(Calendar.HOUR, -3); // three hours ago
Long since = calendar.getTimeInMillis();

if (countLocationHistory(Veery.HISTORY_RAW,  since,  until) > 0){
    Veery.Locations locations =  veery.getLocationHistory(Veery.HISTORY_RAW, since, until);

    JSONObject geoJsonData1 = locations.toGeoJSON(veery.GEOJSON_MULTIPOINT);

    if (geoJsonData1 != null) {
        GeoJsonLayer layer = new GeoJsonLayer(mMap, geoJsonData1); // see Google Maps API
        setGeoJsonStyle(layer);
        layer.addLayerToMap();
        LatLngBounds latLngBounds = Veery.getBoundingBox(layer);
        if (latLngBounds != null && bMapReady)
            mMap.animateCamera(CameraUpdateFactory.newLatLngBounds(latLngBounds,100));
    }
}
