android location base notifications

I want to create an android app

that will send the device location after the app's installation

and every 15 minutes

What is the best way to do so?

1) I can create a timer inside the App's main Activity.

but then it will be stopped when the app is on the background. So I understand I have to create a service.

But then, how do I register it to work from device start up (after turning the device on and forever after)?

2) I saw this push notification tutorial, I think it doesn't fit my needs as the server sends the notification in broadcast, no?

I want different notifications to users based on their current location.

I want the user to actively send GPS location and then receive custom push to his location

(GEO based push notification)

Would you use something like the guy answered here?

If you are using google map android api, then there is a interface calls locationOnChange(LatLng points), this will be called every X min or sec ( X is defined by you ), that bascially gets your current location at giving LatLng point. Then if I was you, I would use NotificationManager to push the notification with the updated point to my phone

Here is the code I would do for this. 

    //At OnCreate


    mLocationClient = new LocationClient(this, this, this);
        mLocationRequest = LocationRequest.create();
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        mLocationRequest.setInterval(UPDATE_INTERVAL);
        mLocationRequest.setFastestInterval(FASTEST_INTERVAL);

mLocationClient.requestLocationUpdates(mLocationRequest, this)

//Google Map interface

    @Override
    public void onLocationChanged(Location location)

//inside I would use the notificationManager to push the location
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                    context).setSmallIcon(R.drawable.btn_star)
                    .setContentTitle("My notification~~~~")
                    .setContentText("Hello World!~~~~")
                    .setStyle(new NotificationCompat.BigTextStyle().bigText(s));

            NotificationManager mNotificationManager = (NotificationManager) context
                    .getSystemService(Context.NOTIFICATION_SERVICE);

            mNotificationManager.notify(123, mBuilder.build());

You can start the service by making a broadcast Receiver which listens to boot completed. Then start service in it. As far as getting location every 15 minutes is concerned you can use following code to get location every 15 minutes :-

locationManager.requestLocationUpdates(usedLocationService, updateTime, updateDistance, this);

replace updateTime with 90000 for 15 minutes. You should implement locationManager in your service.

If you want to do something on a time-based interval, I suggest looking into AlarmManager:

Alarms (based on the AlarmManager class) give you a way to perform time-based operations outside the lifetime of your application.
