Android get current location (latitude and longitude) using GPS

Android get current location (latitude and longitude) using GPS

Step 1 : Create a project and add these permissions to AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission. ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />

Step 2 : Create a Service class named GpsTracker and paste these code . Here implemented LocationListener



import android.Manifest;
import android.app.Activity;
import android.app.Service;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.provider.Settings;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AlertDialog;
import android.util.Log;

class GpsTracker extends Service implements LocationListener {
    private final Context mContext;
    // flag for GPS status
    boolean isGPSEnabled = false;
    // flag for network status
    boolean isNetworkEnabled = false;
    // flag for GPS status
    boolean canGetLocation = false;
    Location location; // location
    double latitude; // latitude
    double longitude; // longitude
    // The minimum distance to change Updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
    // The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
    // Declaring a Location Manager
    protected LocationManager locationManager;
    public GpsTracker(Context context) {
        this.mContext = context;
        getLocation();
    }
    public Location getLocation() {
        try {
            locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE);
            // getting GPS status
            isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
            // getting network status
            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
            if (!isGPSEnabled &amp;&amp; !isNetworkEnabled) {
                // no network provider is enabled
            } else {
                this.canGetLocation = true;
                // First get location from Network Provider
                if (isNetworkEnabled) {
                    //check the network permission
                    if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &amp;&amp; ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                        ActivityCompat.requestPermissions((Activity) mContext, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 101);
                    }
                    locationManager.requestLocationUpdates(

                    if (locationManager != null) {
                        location = locationManager
                                .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        if (location != null) {
                            latitude = location.getLatitude();
                            longitude = location.getLongitude();
                        }
                    }
                }
                // if GPS Enabled get lat/long using GPS Services
                if (isGPSEnabled) {

                        }
                        locationManager.requestLocationUpdates(

                                MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                        Log.d("GPS Enabled", "GPS Enabled");
                        if (locationManager != null) {
                            location = locationManager
                                    .getLastKnownLocation(LocationManager.GPS_PROVIDER);
                            if (location != null) {
                                latitude = location.getLatitude();

        }
        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);
        }
    }

    public void showSettingsAlert(){
        AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
        // Setting Dialog Title
        alertDialog.setTitle("GPS is settings");
        // Setting Dialog Message
        alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
        // On pressing Settings button
        alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {

    }
}


Step 3 : Now call the GpsTracker class from Activity class

 
      GpsTracker gpsTracker;

       gpsTracker = new GpsTracker(EmployeeDataActivity.this);
        if(gpsTracker.canGetLocation()){
            double latitude = gpsTracker.getLatitude();
            double longitude = gpsTracker.getLongitude();

        }else{
            gpsTracker.showSettingsAlert();
        }
