The best way to do that is to create a PendingIntent for a Service and register it with the AlarmManager:

Intent i = new Intent(this, LocationService.class);
PendingIntent pitch = PendingIntent.getService(this, 1, intent, PendingIntent.FLAG_CANCEL_CURRENT);        
AlarmManager am = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP,0,60*60*1000, pi);  /* starting Service every hours. */

This will ensure that the Service is periodically already at regular intermissions, independent on wether the user must brought the app to the spotlight or does.

How to start a Service when the Google application is started?

You can beginning the Service automatically on application start by extending the Application class:

public class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        startService(new Intent(this, NetworkService.class));
    }

}

and modify the applications tag in your manifest with

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name"
    android:name="com.mycompanydomain.MyApp">

This works because the Petition class is single by the primary entities to be created when an app launches. This wishes startup the Gift irrespective of what the launch Activity is.
