Android Service Stops When App Is Closed

make you service like this in your Mainifest

 <service
            android:name=".sys.service.youservice"
            android:exported="true"
        android:process=":ServiceProcess" />

then your service will run on other process named ServiceProcess

---

if you want make your service never die :

1. onStartCommand() return START_STICKY

2. onDestroy() -> startself

3. create a Deamon service

4. jin -> create a Native Deamon process, you can find some open-source projects on github

5. startForeground() , there is a way to startForeground without Notification ,google it

This may help you. I may be mistaken but it seems to me that this is related with returning START_STICKY in your onStartCommand() method. You can avoid the service from being called again by returning START_NOT_STICKY instead.

I'm in the same situation, so far I learned when the app is closed the service get closed also because they are in a one thread, so the service should be on another thread in order fot it not to be closed, look into that and look into keeping the service alive with alarm manager here an example http://www.vogella.com/articles/AndroidServices/article.html this way your service won't be shown in notification.

lastly, after all the research I've done I'm coming to realize that the best choice for a long running service is startForeground(), because it is made for that and the system actually deals with your service well.
