I have following LocationService.java service class.
public class LocationService extends Service
implements LocationListener,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private static final long INTERVAL = 1000 * 60;
private static final long FASTEST_INTERVAL = 1000 * 5;
Location mLastLocation;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
String lat, lon;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mGoogleApiClient.connect();
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onConnected(Bundle bundle) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
lat = String.valueOf(mLastLocation.getLatitude());
lon = String.valueOf(mLastLocation.getLongitude());
Util.WriteSharePrefrence(getApplicationContext(), "track_lat", "" + lat);
Util.WriteSharePrefrence(getApplicationContext(), "track_lng", "" + lon);
}
}
#Override
public void onCreate() {
int permissionCheck = ContextCompat.checkSelfPermission(LocationService.this, Manifest.permission.ACCESS_FINE_LOCATION);
if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
//Execute location service call if user has explicitly granted ACCESS_FINE_LOCATION..
buildGoogleApiClient();
}
}
#Override
public void onConnectionSuspended(int i) {
}
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
#Override
public void onLocationChanged(Location location) {
if (location != null) {
Util.WriteSharePrefrence(getApplicationContext(), "track_lat", "" + location.getLatitude());
Util.WriteSharePrefrence(getApplicationContext(), "track_lng", "" + location.getLongitude());
}
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
buildGoogleApiClient();
}
#Override
public void onDestroy() {
super.onDestroy();
}
}
In the above location service what I am doing is.
1. Set fastest interval to refresh the location every 5 sec.
2. Once location availabe onLocationChanged() will be take place. Inside onLocationChanged() method I am writing current latitude and longitude in the shared preference.
3. This service will be running 24 hours in the background to get current location.
I have Mentioned both location condition in my manifest like below:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
My Issue is :
Some times onLocationChanged() method taking wrong latitude longitude
for example : user device in India and it taking USA address. The device version is Xolo - 4.2.1.(India)
Is it device specific issue? Or something I need to change in my code?
What should I do to make my location service better ?
Use Network or GPS providers or Passive if you want
public void Request_LocationUpdate(String type)
{
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(getActivity(),new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION}, 12);
}
else
{
LocationManager locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
switch (type)
{
case "Passive":
locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER,10000,10,locationListener);
break;
case "GPS":
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,10000,10,locationListener);
break;
case "Network":
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,10000,10,locationListener);
break;
}
}
}

I am developing offline car tracker android application. It will update location after 5 min and stores it in SQLite.I used FusedLocationAPI but can not get accurate location while travelling in bus without Internet. I am getting accuracy 999m and getting same location after every 5 minutes.
I set alarm manager to 5 minutes.
public static void startAlarmManager(Context context)
{
preferences =context.getSharedPreferences(Constant.SHARED_PREF_NAME, Context.MODE_PRIVATE);
int duration= Integer.parseInt(preferences.getString(Constant.DURATION_SHARED_PREF,Constant.CONSTANT_DURATION_SHARED_PREF));
Log.d("duration",duration+"");
alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
gpsTrackerIntent = new Intent(context, GpsTrackerAlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(context, 0, gpsTrackerIntent, 0);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(),
5*60000,
pendingIntent);
}
It will fire broadcast receiver.
public class GpsTrackerAlarmReceiver extends WakefulBroadcastReceiver {
private static final String TAG = "GpsTrackerAlarmReceiver";
#Override
public void onReceive(Context context, Intent intent) {
LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE );
boolean statusOfGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if(statusOfGPS) {
context.startService(new Intent(context, LocationService.class));
}
}
}
This is location service. I am getting location with this way.

Please help...if i am wrong. Thanks in advance.
When GPS is not practical you can use LocationManager.NETWORK_PROVIDER, this is location from the phone carrier that is less accurate than GPS but is available everywhere the carrier has a tower. The way I do it is a set a flag isGpsAvailable() to see if that is true I use GPS otherwise I use network provided location. This Google's doc provides detailed solutions including code snippets that you can use and change the way you it fits your needs.
I have a jobScheduler with fusedLocationApi provider. It works alright but once a while it gives null value for a no. of time (6-7 times in a sequence). I tried onLocationChanged() and LocationServices.FusedLocationApi.requestLocationUpdates(), both gives null values at same time. How can I improve it? I have set high accuracy or Gps,wifi and mobile networks as locating method in device setting. thanks in advance.
One more thing, 80% of the null value are received when there is no wifi. I think Fused Api should have worked well without wifi as well Since there is gps available, isn't it?

Try this
Create a background service class like this
public class LocationBackGroundService extends Service implements LocationListener,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "LocationBackGroundService";
private static final long INTERVAL = 100;
private static final long FASTEST_INTERVAL = 100;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
Location mCurrentLocation;
Context mCOntext;
public void LocationBackGroundService(Context mContext) {
this.mCOntext = mContext;
}
protected void createLocationRequest() {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
#Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
mGoogleApiClient.connect();
}
#Override
public void onCreate() {
super.onCreate();
if (!isGooglePlayServicesAvailable()) {
// finish();
}
createLocationRequest();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
if (mGoogleApiClient.isConnected()) {
startLocationUpdates();
}
}
private boolean isGooglePlayServicesAvailable() {
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (ConnectionResult.SUCCESS == status) {
return true;
} else {
return false;
}
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onConnected(Bundle bundle) {
startLocationUpdates();
}
protected void startLocationUpdates() {
PendingResult<Status> pendingResult = LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, mLocationRequest, this);
Log.d(TAG, "Location update started ..............: ");
}
#Override
public void onConnectionSuspended(int i) {
Toast.makeText(this, "OnConnection Suspended", Toast.LENGTH_SHORT).show();
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(this, "OnConnection Failed", Toast.LENGTH_SHORT).show();
}
#Override
public void onLocationChanged(Location location) {
if (null != mCurrentLocation) {
mCurrentLocation = location;
String lat = String.valueOf(mCurrentLocation.getLatitude());
String lng = String.valueOf(mCurrentLocation.getLongitude());
}
}
}
And call when activity starts like this
startService(new Intent(this, yourBackgroundServiceName.class));
and in menifest
<service android:name=".yourBackgroundServiceName"></service>
and don;t forget to add run time permissions before stating a service
I am trying to get continuous location updates by running a background service. While I debug the code onConnected(Bundle b) is called and location update request is called. But onLocationChanged(Location location) is never called. Below is my code:

}
}
I can't understand where I am making mistake, while I have followed android docs. I am testing on real device and app has location permissions.
service in menifest:
<service
android:name=".locations.LocationUpdateService"
android:enabled="true"
android:exported="false"></service>
Call of service in activity:
startService(new Intent(BaseActivity.this, LocationUpdateService.class));
What is your android phone SDK and how are you asking for the permissions on the manifest file?
If your phone SDK is 23 or higher the way you ask for permissions is different.
It was just a stupid debugging issue. I found my device location Access was off in advance settings.
all i am trying to get the location of the device but it always returns null. I know for the first time it will return null but again and again it is returning null. Below is my code. Please help me to solve this .

Thanks in advance
It seems, that you try to get last location when your LocationClient connected. But you need to request a location update to receive your current location instead of calling getLastLocation(). You created your own LocationRequest in createLocationRequest() method but you haven't ever used it in code.
Example code:
LocationServices.FusedLocationApi.requestLocationUpdates(yourGoogleApiClient, yourLocationRequest, yourLocationListener);
Update:
End when you received new location in yourLocationListener you need to you have to stop receiving location updates:
private LocationListener mLocationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Log.v("onLocationChanged","onLocationChanged");
if(mGoogleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mLocationListener);
mGoogleApiClient.disconnect();
}
//your code here }
};
More details you can find here.
Hope it will help you.
I have a service that will send location updates in a background thread. I have declared the service in the manifest as:
<service android:name="mypackage.LocationUpdater"></service>
I get my data from the activity in OnStartComand. But the OnLocationChanged is not called at all. I am unable to call the sendLocation() method from anywhere in the service.
public class LocationUpdater extends Service implements ConnectionCallbacks, OnConnectionFailedListener, LocationListener {
LocationListener mLocationListener;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
Location mLastLocation; //this object should be used to request location updates
String p = "test", d = "test";
#Override
public void onCreate() {
buildGoogleApiClient();
}
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)

.build();
}
protected void createLocationRequest() {
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(5000);
mLocationRequest.setFastestInterval(3000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
p = intent.getStringExtra("ptok");
d = intent.getStringExtra("dtok");
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_NOT_STICKY;
}
#Override
public void onConnected(Bundle connectionHint) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
mLocationRequest = LocationRequest.create();
mLocationRequest.setInterval(5000);
mLocationRequest.setFastestInterval(3000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
if (mLastLocation != null) {
String latitude = String.valueOf(mLastLocation.getLatitude());
String longitude = String.valueOf(mLastLocation.getLongitude());
sendLocation(p, latitude, longitude, d);
}
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
if(location != null) {
double latitude = location.getLatitude();
double longitude = location.getLongitude();
Log.i("info", "Latitude :: " + latitude);
Log.i("info", "Longitude :: " + longitude);
//sending location details
sendLocation(p, String.valueOf(latitude), String.valueOf(longitude), d);
}
}
}
I have to also add onConnected is never called as well. All I see is onStartComand being called and pass the values sent from my activity using intent.
The docs didn't describe this but based on this SO accepted answer, I had to explicitly call mGoogleApiClient.connect(); in my onCreate method. You call that in onStart(); from activity.
