How to get location of android device by its android id

Question

I am new in android and recently start learning about Android and I am trying to get location of any android device by its unique android id. By that I can track the approx or exact location either by GPS or network provider. In detail I mean to say that whenever i enter any Android id in my app i can get device location in my application. Thanks for your kind help.

Answer 1

Finally I am able to do with this code:

public class MyService extends Service implements LocationListener{
String GPS_FILTER = "";
Thread triggerService;
LocationListener locationListener;
LocationManager lm;
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meter

private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000 * 60 * 3; // 1 minute
protected LocationManager locationManager;
boolean isRunning = true;

Calendar cur_cal = Calendar.getInstance();

Location location;
double latitude; // latitude
double longitude;
UserFunctions userFunction;
private JSONObject json;
private AlertDialogManager alert = new AlertDialogManager();

private static String KEY_SUCCESS = "success";
private static String KEY_ERROR = "error";
private static String KEY_ERROR_MSG = "error_msg";
private static String KEY_FLAG = "flag";
String android_id ;
String userName;

@Override
public void onCreate() {
    // TODO Auto-generated method stub
    super.onCreate();
    Intent intent = new Intent(this, MyService.class);
    PendingIntent pintent = PendingIntent.getService(getApplicationContext(),
            0, intent, 0);
    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    android_id = Settings.Secure.getString(getContentResolver(),
                Settings.Secure.ANDROID_ID);
    if (getAccount() != null) {
        userName = getAccount();
    }

    GPS_FILTER = "MyGPSLocation";
    // locationManager = (LocationManager)
    // getSystemService(Context.LOCATION_SERVICE);
    // locationManager.requestLocationUpdates(
    // LocationManager.GPS_PROVIDER,
    // MINIMUM_TIME_BETWEEN_UPDATES,
    // MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
    // new MyLocationListener());
    cur_cal.setTimeInMillis(System.currentTimeMillis());
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cur_cal.getTimeInMillis(),
            60 * 1000*3, pintent);
}

@Override
public void onStart(Intent intent, int startId) {
    // TODO Auto-generated method stub
    super.onStart(intent, startId);
    //turnGPSOn();
    /*Toast.makeText(getApplicationContext(), "Hello1", Toast.LENGTH_LONG)
            .show();*/
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
     locationListener = new MyLocationListener();
     locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER,
                MINIMUM_TIME_BETWEEN_UPDATES,
                MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, (LocationListener) this);
     if (locationManager != null) {
            location = locationManager
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if (location != null) {
                latitude = location.getLatitude();
                longitude = location.getLongitude();
                /*Toast.makeText(getApplicationContext(), latitude + ", ll" + longitude, Toast.LENGTH_LONG)
                .show();*/
                userFunction = new UserFunctions();
                new YourAsyncTaskLogin().execute();
            }
        }

     location =locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
            MINIMUM_TIME_BETWEEN_UPDATES, 1.0f, locationListener);

Answer 2

if you want to get location of any device who has your app in their mobile , you can get it , firstly in your app you can upload locations to your server with memberid(you can set it , unique for every device) for every x time(you can set it how many times you update the location). And then you can check your db on your server which device in where.

(my advice you can use webservice to update db on your server)
