I'm trying to retrieve location using LocationManager following this tutorial.
I'm running the code on an android device running Marshmallow and I have checked the permission and running below code once the permission is granted.
Here's my code:
public Location getLocation() {
try {
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled
Log.d("noProviderEnabled", "called");
} else {
this.canGetLocation = true;
// First get location from Network Provider
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
currentLatDouble = location.getLatitude();
currentLngDouble = location.getLongitude();
}
}
}
// if GPS Enabled get lat/long using GPS Services
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
currentLatDouble = location.getLatitude();
currentLngDouble = location.getLongitude();
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
Even though WiFi is enabled, isNetworkEnabled=locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); is returning false and Log.d("noProviderEnabled", "called"); is getting printed out.
Update: when I turned the GPS on and then run the above code.. only the isNetworkEnabled returned true and isGPSEnabled still returned false.
What's wrong here? Why am I unable to retrieve location using LocationManager.NETWORK_PROVIDER even when WiFi is enabled?
P.S.: This is working perfectly fine on android L and below.
