Question

I want to keep my application running in background
I have an application that sends the user’s location to our server
I have the following code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    LocationManager locationManager;
    String context = Context.LOCATION_SERVICE;
    locationManager = (LocationManager)getSystemService(context);

    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setAltitudeRequired(false);
    criteria.setBearingRequired(false);
    criteria.setCostAllowed(true);
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    String provider = locationManager.getBestProvider(criteria, true);

    updateWithNewLocation(null);

    locationManager.requestLocationUpdates(provider, (10*60*1000), 10,
                                           locationListener);
}
private final LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      updateWithNewLocation(location);
    }

    public void onProviderDisabled(String provider){
      updateWithNewLocation(null);
    }

    public void onProviderEnabled(String provider){ }
    public void onStatusChanged(String provider, int status, 
                                Bundle extras){ }
  };
  public void updateWithNewLocation(Location location) {


        if (location != null) {
            Dbhelper helper = new Dbhelper(this);
            final SQLiteDatabase db = helper.getWritableDatabase();
            long time = System.currentTimeMillis();
            SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss");
            final String curTime = df.format(time);
            final double lat = location.getLatitude();
            final double lng = location.getLongitude();
            final double alt = location.getAltitude();
            System.out.println(lat);
            System.out.println(lng);
            System.out.println(alt);
            db.execSQL("INSERT INTO location (longitude,latitude,altitude,tgl_buat) VALUES " +
            "('"+lng+"','"+lat+"','"+alt+"','"+curTime+"')");
            db.close();
            /*Timer timer = new Timer();
            timer.scheduleAtFixedRate(new TimerTask(){
                @Override
                public void run(){
                    db.execSQL("INSERT INTO location (longitude,latitude,altitude,tgl_buat) VALUES " +
                            "('121.2149012','-6.217837','0.0','2012-05-07 10:20:01')");
                    db.close();
                }
            }, 10*60*1000, 10*60*1000);*/

          } 
       }

I want my applicatioin to be running in the background. I want it to launch automatically when the phone is turned on

Answer 1

A very simple answer for your problem is to use Service. It will allow you to perform variety of tasks while being in background and is your best bet for sending your location to server silently.
