Question

I am trying to fetch location based on WiFi/3G/4G connection but it always returns 0.0 as latitude and longitude. If same code is used

Answer 1

The steps to be followed :

Step 1 : check the following permission in Manifest File

Step 2 : check the service class

import android.annotation.SuppressLint;


public class  GPSTracker extends Service implements LocationListener {

public static boolean isGPSEnabled = false;
public static boolean isNetworkEnabled = false;
static boolean canGetLocation = false;

Location location; // location
double latitude; // latitude
double longitude; // longitude
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 2; // 2 meters
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
protected LocationManager locationManager;

@Override
public IBinder onBind(Intent arg0) {
    return null;
}
@SuppressWarnings("static-access")
@Override
public void onCreate() {
    super.onCreate();
    Log.d("onCreate", "Success !");
        latitudeAndLongtitude();
}

public void latitudeAndLongtitude()
{
    locationManager = (LocationManager) getApplicationContext().getSystemService(LOCATION_SERVICE);
    isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    if (!isGPSEnabled && !isNetworkEnabled) {
        Toast.makeText(getApplicationContext(), "No provider found!", Toast.LENGTH_SHORT).show();
    }else{
        GPSTracker.canGetLocation = true;
        if(isGPSEnabled)
        {
            if (location == null) {
            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,MIN_TIME_BW_UPDATES,MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
            Log.d("Network", "GPS");
            if (locationManager != null) {
                Log.d("locationManager", "is not null ");
                location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                if (location != null) {
                    Log.d("Network", "GPS lat and long gets ");
                    Toast.makeText(getApplicationContext(), "isNetworkEnabled!", Toast.LENGTH_SHORT).show();
                    latitude = location.getLatitude();
                    longitude = location.getLongitude();
                    Helper.savePreferences(getApplicationContext(), NameConversion.LATITUDE,String.valueOf(latitude));
                    Helper.savePreferences(getApplicationContext(), NameConversion.LONGITUDE,String.valueOf(longitude));
                }else{
                    Log.d("location", "is getting null ");
                }
            }
        }
    }
        else 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) {
                    //Toast.makeText(getApplicationContext(), "isGPSEnabled!", Toast.LENGTH_SHORT).show();
                    latitude = location.getLatitude();
                    longitude = location.getLongitude();
                    Helper.savePreferences(getApplicationContext(), NameConversion.LATITUDE,String.valueOf(latitude));
                    Helper.savePreferences(getApplicationContext(), NameConversion.LONGITUDE,String.valueOf(longitude));
                }
            }
        }
    }
}
public Location getLocation() {
    return location;
}
/**
 * Stop using GPS listener Calling this function will stop using GPS in your
 * app
 * */
public void stopUsingGPS() {
    if (locationManager != null) {
        locationManager.removeUpdates(GPSTracker.this);
    }
}
/**
 * Function to get latitude

public double getLatitude() {
    if (location != null) {
        latitude = location.getLatitude();
    }
    // return latitude
    return latitude;
}
/**

public double getLongitude() {
    if (location != null) {
        longitude = location.getLongitude();
    }
    // return longitude
    return longitude;
}

public void sendLocationToServer() {
    Log.i("sendLocationToServer", "Called!");

}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.i("onDestroy", "Called!");
    stopSelf();

}

/**
 * Function to check GPS/wifi enabled
 * 
 * @return boolean
 * */
@SuppressWarnings("static-access")
public boolean canGetLocation() {
    return this.canGetLocation;
}

/**
 * Function to show settings alert dialog On pressing Settings button will
 * lauch Settings Options
 * */
@SuppressLint("NewApi")

@Override
public void onLocationChanged(Location location) {

    latitudeAndLongtitude();
}

@Override
public void onProviderDisabled(String provider) {
}

@Override
public void onProviderEnabled(String provider) {
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}}

step 3 : Enable the service in Manifest file

inside application tag

setp 4 : start the service in where you want

Hope this will work if you face stil problem may be your mobile will not get the GPS and Network Locaiton .
