Android method implementations for background service

Here's the situation.

I have an app with a database. The db must update every X minutes. The data is on a web server. The communication with the server will take about 10 httpget requests. So far accomplished a background service and a HTTPget function for getting the new information and updating the db. The problem is that it must update in background at that X minutes. I'm unsure what and how to realize that.

1.Use a delay function and run it at every X minutes ? 2.Use a sleep thread and wake it up at every X minutes ?

Or something else ?

Use Intent Service and run it periodically every X minutes using alarm manager.

Use a Broadcast Receiver to trigger the intent service , so that the service continues to run even when user switches on their phone

Step 1. Create your Intent Service

public class SimpleIntentService extends IntentService {


    public SimpleIntentService() {
        super("SimpleIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
 // TODO your task

    }
}

Step 2. Repeating pending intent for service using AlarmManager

Intent myIntent = new Intent(context, StartMyServiceReceiver.class);

        PendingIntent pi = PendingIntent.getBroadcast(context, 0, myIntent, 0);

        alarmMgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                SystemClock.elapsedRealtime(),
                AlarmManager.INTERVAL_FIFTEEN_MINUTES, pi);

Step 3. In order to ensure that your service runs even after switch off when phone boots up again , create an PowerEventReceiver

public class PowerEventReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {


        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            //start your service
        }

    }
}

P.S: Remember to register your service and receivers in In AndroidManifest.
