When you want to exit from whole application use below code

         Intent intent = new Intent(Intent.ACTION_MAIN);
         intent.addCategory(Intent.CATEGORY_HOME);
         intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         startActivity(intent);
         finish();

Get Current Latitude and Longitude

To get current latitude and longitude 

create one class name CurrentLocListener 

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.os.Bundle;
import android.util.Log;


public class CurrentLocListener implements LocationListener {
   
    private static final String TAG = "CurrentLocListener - ";
   
    Context mContext;
   
    String latitude,longitude,token;
   
    public CurrentLocListener(Context context){
        mContext = context;
    }

    public void onLocationChanged(Location location) {
        Log.i("Lock Me If You Can", TAG + "onLocationChanged - Latitude: " + String.valueOf(location.getLatitude()) + " Longitude: " + String.valueOf(location.getLongitude()));
        Utility.setSharedKey("Latitude", String.valueOf(location.getLatitude()), mContext);
        Utility.setSharedKey("Longitude", String.valueOf(location.getLongitude()), mContext);
      
        //Intent mIntent = new Intent(General.ACTION_LOCATION_CHANGED);
        //mContext.sendBroadcast(mIntent);
    }

    public void onProviderDisabled(String provider) {
        Log.i("Lock Me If You Can", TAG + "onProviderDisabled - ");
    }

    public void onProviderEnabled(String provider) {
        Log.i("Lock Me If You Can", TAG + "onProviderEnabled - ");
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        Log.i("Lock Me If You Can", TAG + "onStatusChanged - ");
    }
}
 

in your main activity create below method


public static void registerLocationListener(Context context) {
        LocationManager lManager = null;
        CurrentLocListener cListener = null;
        lManager = (LocationManager) context
                .getSystemService(Context.LOCATION_SERVICE);

        boolean isGpsEnabled = false;
        boolean isNetworkEnabled = false;

        isGpsEnabled = lManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        isNetworkEnabled = lManager
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        if (isGpsEnabled) {
            cListener = new CurrentLocListener(context);
            lManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
                    cListener);
            Location location = lManager
                    .getLastKnownLocation(LocationManager.GPS_PROVIDER);
            if (location != null) {
                setSharedKey("Latitude",
                        String.valueOf(location.getLatitude()), context);
                setSharedKey("Longitude",
                        String.valueOf(location.getLongitude()), context);
            }
        }
        if (isNetworkEnabled) {
            cListener = new CurrentLocListener(context);
            lManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
                    0, 0, cListener);
            Location location = lManager
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if (location != null) {
                setSharedKey("Latitude",
                        String.valueOf(location.getLatitude()), context);
                setSharedKey("Longitude",
                        String.valueOf(location.getLongitude()), context);
            }
        }
    }

 public static void setSharedKey(String key, String value, Context context) {
        SharedPreferences spre = context.getSharedPreferences(
                context.getPackageName(), Context.MODE_PRIVATE);
        SharedPreferences.Editor prefEditor = spre.edit();
        prefEditor.putString(key, value);
        //prefEditor.clear();
        prefEditor.commit();
    }

    public static String getSharedKey(String key, Context context) {
        SharedPreferences spre = context.getSharedPreferences(
                context.getPackageName(), Context.MODE_PRIVATE);
        return spre.getString(key, "");
    }
    

in your oncreate method write below code

registerLocationListener(mcontext);
latitude = Utility.getSharedKey("Latitude",mcontext);
longitude = Utility.getSharedKey("Longitude",mcontext);
