You can use AlarmManager or JobScheduler - for more info refer: https://developer.android.com/topic/performance/scheduling.html look for their tutorial and implement using any one of the two. After implementing in case you face any issue then post it in here. — Shadow Droid, Nov 11 '16 at 08:07

I suggest using rxJava library - it is very convenient:

Subscription repeatingTask = 
Observable.interval(6, Timeunit.SECONDS)
// receive notification on background thead
.observeOn(Schedulers.computation())
.map( t -> {
  // do your work;
 return result;
}
.map(result -> {
 sendResult();
return result
})
// notify UI
.observeOn(AndroidSchedulers.mainThread)
.subscribe(r -> {
 // update UI
});

// unsubscribe when polling is no longer needed:
if (subscription != null && !subscription.isUnsubscribed()){
   subscription.unsubscribe();
   subscription = null;
}

You can solve this by creating a foregroundService. This might solve your problem of your service getting killed on low memory. A foreground service

is a service that the user is actively aware of and is not a candidate for the system to kill when low on memory. Source

For a good examples of a foreground Service read through this thread: Android - implementing startForeground for a service?

Also to be informed when the location changes check out this answer: https://stackoverflow.com/a/8600896/5183341

I also created a similar service than you are trying to do and allways had problems with my service getting killed on some devices. (Like the LG2 with API19). I tryed alot of different solotions like using an alarmmanager which restarts the service and so on. The only which worked solid on all devices was using a foregroundService.
