services are automatically maintains the user current location. Recently google
released through google I/O “Fused
Location Providers”. What is the meaning of fused location?
Taking Gps, wifi, Mobile network, Sensors which provides the location and taking best
location out of these, By fusing these will give the better location and
follows the user position continuously.
How to implement this
api to the android application?
Android providing google play services
library, which will provide the all apis which are required for implementing
fused location providers.
Location providers
sends the user current location to the application through LocationClient.
Declare the permissions in the manifest.xml file
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Class will implement implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,
LocationListener {
private LocationClient mLocationclient;
int resp =
GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getActivity());
if (resp ==
ConnectionResult.SUCCESS) {
mLocationclient = new
LocationClient(getActivity(), this, this);
mLocationclient.connect();
}
else {
GooglePlayServicesUtil.getErrorDialog(resp,
getActivity(), 2);
}
@Override
public void onConnected(Bundle
arg0) {
Log.i("location", "onConnected");
if (mLocationclient != null && mLocationclient.isConnected()) {
Location
loc = mLocationclient.getLastLocation();
if (loc != null) {
String locLatitude = "" + loc.getLatitude();
String locLongitude = "" + loc.getLongitude();
}
else {
LocationManager
manager = (LocationManager) getActivity()
.getSystemService(Context.LOCATION_SERVICE);
if
(!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
buildAlertMessageNoGps();
}
}
}
}
@Override
public void onDisconnected() {
Log.i("location", "onDisconnected");
}
@Override
public void
onConnectionFailed(ConnectionResult result) {
Log.i("location", "onConnectionFailed");
}
@Override
public void
onLocationChanged(Location location) {
if (location != null) {
String locationLatitude = "" +
location.getLatitude();
String locLongitude = "" + location.getLongitude();
}
}
