Yea that isn't necessary. LeanData is already a service and is built so that it can withstand being killed and recreated. The problem comes with KitKat where if the system kills a service, it no longer restarts (shows 0 processes in Running Services) like it should and did in other versions of Android. This is why you can't swipe the app away from the recent apps list. If the system is low on memory the system can also kill the service and then it fails to restart. I'm going to add an option for a persistent notification.

It is not necessary to do a persistent notification, as soon as already we have formed the application to put an option in order that when we extinguish it completely and we return to light the telephone start the application in the beginning, like that already we will not have this problems of which we erase it of the recent applications since it is not going to go out for us there and already the application was not closed, this way there have been solved some applications that also it happens to them in kitkat
