Android Location Manager Get GPS location if no GPS then get to Network Provider location

I am using this given below code to get locations   public Location getLocation             try               mLocationManager    LocationManager  context getSystemService LOCATION SERVICE                   getting GPS status             boolean isGPSEnabled   mLocationManager isProviderEnabled LocationManager GPS PROVIDER                   getting network status             boolean isNetworkEnabled   mLocationManager isProviderEnabled LocationManager NETWORK PROVIDER                if   isGPSEnabled  amp  amp   isNetworkEnabled                       no network provider is enabled               else                      First get location from Network Provider                 if  isNetworkEnabled                        mLocationManager requestLocationUpdates  LocationManager NETWORK PROVIDER   MIN TIME BW UPDATES   MIN DISTANCE CHANGE FOR UPDATES  this                       Log d  Network    Network                        if  mLocationManager    null                            location   mLocationManager getLastKnownLocation LocationManager NETWORK PROVIDER                           if  location    null                                lat   location getLatitude                                lng   location getLongitude                                                                                        get the location by gps                 if  isGPSEnabled                        if  location    null                            mLocationManager requestLocationUpdates LocationManager GPS PROVIDER MIN TIME BW UPDATES MIN DISTANCE CHANGE FOR UPDATES  this                           Log d  GPS Enabled    GPS Enabled                            if  mLocationManager    null   location   mLocationManager getLastKnownLocation LocationManager GPS PROVIDER                               if  location    null                                    lat   location getLatitude                                    lng   location getLongitude                                                                                                                             catch  Exception e                e printStackTrace                       return location          It is working properly  but I would like to get GPS location first  and in case if it is unavailable   location manager should query for Network provider  in which I am getting trouble   Please  recommend me the good way to do this

I made some changes in above code to look for a location fix by both GPS and Network for about 5sec and give me the best known location out of it.

public class LocationService implements LocationListener {

    boolean isGPSEnabled = false;

    boolean isNetworkEnabled = false;

    boolean canGetLocation = false;

    final static long MIN_TIME_INTERVAL = 60 * 1000L;

    Location location;


    // The minimum distance to change Updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 0; // 10

    // The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 1; // 1 minute

    protected LocationManager locationManager;

    private CountDownTimer timer = new CountDownTimer(5 * 1000, 1000) {

        public void onTick(long millisUntilFinished) {

        }

        public void onFinish() {
            stopUsingGPS();
        }
    };

    public LocationService() {
        super(R.id.gps_service_id);
    }


    public void start() {
        if (Utils.isNetworkAvailable(context)) {

            try {


                timer.start();


                locationManager = (LocationManager) context
                        .getSystemService(Context.LOCATION_SERVICE);

                isGPSEnabled = locationManager
                        .isProviderEnabled(LocationManager.GPS_PROVIDER);

                isNetworkEnabled = locationManager
                        .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
                this.canGetLocation = true;
                if (isNetworkEnabled) {
                    locationManager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER,

                                .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        if (tempLocation != null
                                && isBetterLocation(tempLocation,
                                        location))
                            location = tempLocation;
                    }

                    if (locationManager != null) {

                                .getLastKnownLocation(LocationManager.GPS_PROVIDER);

                .isProviderEnabled(LocationManager.GPS_PROVIDER);

        // getting network status
        isNetworkEnabled = locationManager
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        return isGPSEnabled || isNetworkEnabled;
    }

    @Override
    public void onLocationChanged(Location location) {

        if (location != null
                && isBetterLocation(location, this.location)) {

            this.location = location;

        }
    }

    @Override

    @Override

        return location;
    }

    public static boolean isBetterLocation(Location location,
            Location currentBestLocation) {
        if (currentBestLocation == null) {
            // A new location is always better than no location
            return true;
        }

        // Check whether the new location fix is newer or older
        long timeDelta = location.getTime() - currentBestLocation.getTime();
        boolean isSignificantlyNewer = timeDelta > MIN_TIME_INTERVAL;
        boolean isSignificantlyOlder = timeDelta < -MIN_TIME_INTERVAL;
        boolean isNewer = timeDelta > 0;

        // If it's been more than two minutes since the current location,
        // use the new location
        // because the user has likely moved
        if (isSignificantlyNewer) {
            return true;
            // If the new location is more than two minutes older, it must
            // be worse
        } else if (isSignificantlyOlder) {
            return false;
        }

        // Check whether the new location fix is more or less accurate
        int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation
                .getAccuracy());
        boolean isLessAccurate = accuracyDelta > 0;
        boolean isMoreAccurate = accuracyDelta < 0;
        boolean isSignificantlyLessAccurate = accuracyDelta > 200;

        // Check if the old and new location are from the same provider
        boolean isFromSameProvider = isSameProvider(location.getProvider(),
                currentBestLocation.getProvider());

        // Determine location quality using a combination of timeliness and
        // accuracy
        if (isMoreAccurate) {
            return true;
        } else if (isNewer && !isLessAccurate) {
            return true;
        } else if (isNewer && !isSignificantlyLessAccurate
                && isFromSameProvider) {
            return true;
        }
        return false;
    }

}

In the above class, I am registering a location listener for both GPS and network, so an onLocationChanged call back can be called by either or both of them multiple times and we just compare the new location fix with the one we already have and keep the best one.

The recommended way to do this is to use LocationClient   First  define location update interval values  Adjust this to your needs   private static final int MILLISECONDS PER SECOND   1000  private static final long UPDATE INTERVAL   MILLISECONDS PER SECOND   UPDATE INTERVAL IN SECONDS  private static final int FASTEST INTERVAL IN SECONDS   1  private static final long FASTEST INTERVAL   MILLISECONDS PER SECOND   FASTEST INTERVAL IN SECONDS    Have your Activity implement GooglePlayServicesClient ConnectionCallbacks  GooglePlayServicesClient OnConnectionFailedListener  and LocationListener   public class LocationActivity extends Activity implements  GooglePlayServicesClient ConnectionCallbacks  GooglePlayServicesClient OnConnectionFailedListener  LocationListener      Then  set up a LocationClientin the onCreate   method of your Activity   public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState        mLocationClient   new LocationClient this  this  this        mLocationRequest   LocationRequest create        mLocationRequest setPriority LocationRequest PRIORITY HIGH ACCURACY       mLocationRequest setInterval UPDATE INTERVAL       mLocationRequest setFastestInterval FASTEST INTERVAL       Add the required methods to your Activity  onConnected   is the method that is called when the LocationClientconnects  onLocationChanged   is where you ll retrieve the most up-to-date location    Override public void onConnectionFailed ConnectionResult connectionResult        Log w TAG   Location client connection failed        Override public void onConnected Bundle dataBundle        Log d TAG   Location client connected        mLocationClient requestLocationUpdates mLocationRequest  this        Override public void onDisconnected         Log d TAG   Location client disconnected        Override public void onLocationChanged Location location        if  location    null            Log d TAG   Updated Location      Double toString location getLatitude            Double toString location getLongitude            else           Log d TAG   Updated location NULL                    Be sure to connect disconnect the LocationClient so it s only using extra battery when absolutely necessary and so the GPS doesn t run indefinitely  The LocationClient must be connected in order to get data from it    public void onResume         super onResume        mLocationClient connect       public void onStop         if  mLocationClient isConnected              mLocationClient removeLocationUpdates this             mLocationClient disconnect        super onStop        Get the user s location  First try using the LocationClient  if that fails  fall back to the LocationManager   public Location getLocation         if  mLocationClient    null  amp  amp  mLocationClient isConnected              return mLocationClient getLastLocation          else           LocationManager locationManager    LocationManager  this getSystemService Context LOCATION SERVICE           if  locationManager    null                Location lastKnownLocationGPS   locationManager getLastKnownLocation LocationManager GPS PROVIDER               if  lastKnownLocationGPS    null                    return lastKnownLocationGPS                else                   return locationManager getLastKnownLocation LocationManager NETWORK PROVIDER                           else               return null

there are better ways to do it as mentioned on android developer sites http   developer android com guide topics location strategies html

You re saying that you need GPS location first if its available  but what you did is first you re getting location from network provider and then from GPS  This will get location from Network and GPS as well if both are available  What you can do is  write these cases in if  else if block  Similar to-  if   isGPSEnabled  amp  amp   isNetworkEnabled        Can t get location by any way    else        if isGPSEnabled            get location from GPS        else if isNetworkEnabled            get location from Network Provider            So this will fetch location from GPS first  if available   else it will try to fetch location from Network Provider   EDIT   To make it better  I ll post a snippet  Consider it is in try-catch   boolean gps enabled   false  boolean network enabled   false   LocationManager lm    LocationManager  mCtx                  getSystemService Context LOCATION SERVICE    gps enabled   lm isProviderEnabled LocationManager GPS PROVIDER   network enabled   lm isProviderEnabled LocationManager NETWORK PROVIDER    Location net loc   null  gps loc   null  finalLoc   null   if  gps enabled      gps loc   lm getLastKnownLocation LocationManager GPS PROVIDER   if  network enabled      net loc   lm getLastKnownLocation LocationManager NETWORK PROVIDER    if  gps loc    null  amp  amp  net loc    null           smaller the number more accurate result will     if  gps loc getAccuracy    gt  net loc getAccuracy             finalLoc   net loc      else         finalLoc   gps loc              I used this just to get an idea  if both avail  its upto you which you want to take as I ve taken location with more accuracy     else        if  gps loc    null            finalLoc   gps loc        else if  net loc    null            finalLoc   net loc            Now you check finalLoc for null  if not then return it  You can write above code in a function which returns the desired  finalLoc  location  I think this might help

use the fusion API that google developer have developed with fusion of GPS Sensor Magnetometer Accelerometer also using Wifi or cell location to calculate or estimate the location  It is also able to give location updates also inside the building accurately   package com example ashis gpslocation   import android app Activity  import android location Location  import android os Bundle  import android support v7 app ActionBarActivity  import android support v7 app AppCompatActivity  import android util Log  import android widget TextView  import android widget Toast   import com google android gms common ConnectionResult  import com google android gms common GooglePlayServicesUtil  import com google android gms common api GoogleApiClient  import com google android gms common api GoogleApiClient ConnectionCallbacks  import com google android gms common api GoogleApiClient OnConnectionFailedListener  import com google android gms location LocationListener  import com google android gms location LocationRequest  import com google android gms location LocationServices   import java util concurrent Executors  import java util concurrent TimeUnit          Location sample        Demonstrates use of the Location API to retrieve the last known location for a device     This sample uses Google Play services  GoogleApiClient  but does not need to authenticate a user     See https   github com googlesamples android-google-accounts tree master QuickStart if you are    also using APIs that need authentication       public class MainActivity extends Activity implements LocationListener          GoogleApiClient ConnectionCallbacks          GoogleApiClient OnConnectionFailedListener        private static final long ONE MIN   500      private static final long TWO MIN   500      private static final long FIVE MIN   500      private static final long POLLING FREQ   1000   20      private static final long FASTEST UPDATE FREQ   1000   5      private static final float MIN ACCURACY   1 0f      private static final float MIN LAST READ ACCURACY   1       private LocationRequest mLocationRequest      private Location mBestReading  TextView tv      private GoogleApiClient mGoogleApiClient        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState            if   servicesAvailable                  finish                       setContentView R layout activity main   tv   TextView  findViewById R id tv1           mLocationRequest   LocationRequest create            mLocationRequest setPriority LocationRequest PRIORITY HIGH ACCURACY           mLocationRequest setInterval POLLING FREQ           mLocationRequest setFastestInterval FASTEST UPDATE FREQ            mGoogleApiClient   new GoogleApiClient Builder this                   addApi LocationServices API                   addConnectionCallbacks this                   addOnConnectionFailedListener this                   build              if  mGoogleApiClient    null                mGoogleApiClient connect                          Override     protected void onResume             super onResume             if  mGoogleApiClient    null                mGoogleApiClient connect                          Override     protected void onPause    d         super onPause             if  mGoogleApiClient    null  amp  amp  mGoogleApiClient isConnected                  mGoogleApiClient disconnect                              tv setText location                   Determine whether new location is better than current best            estimate         if  null    mBestReading    location getAccuracy    lt  mBestReading getAccuracy                  mBestReading   location                if  mBestReading getAccuracy    lt  MIN ACCURACY                    LocationServices FusedLocationApi removeLocationUpdates mGoogleApiClient  this                                       Override     public void onConnected Bundle dataBundle               Get first reading  Get additional location updates if necessary         if  servicesAvailable                      Get best last location measurement meeting criteria             mBestReading   bestLastKnownLocation MIN LAST READ ACCURACY  FIVE MIN                if  null    mBestReading                        mBestReading getAccuracy    gt  MIN LAST READ ACCURACY                        mBestReading getTime    lt  System currentTimeMillis   -
