Android service, need a service that keeps running

I am a beginner in Android development. I want to build a service that once started, must keep running.

Step 1.) Once user will install the app give some input, service will start. (i'll use IntentService)

Step 2.) Now user moves to other app/close my app. I want to make sure Service should keep running and processing/saving info with current timestamps.

Questions:

1.) How I make sure that the service keeps running/saving data even if user returns after say, 1 month on my app.

2.) I read that every app is a new user and separate VM is provided by the Android, question is when an app is considered to be closed?

3.) If my app closes, related services will also close then?

1.) How I make sure that the service keeps running/saving data even if user returns after say, 1 month on my app.

Once user installs app, you can start STICKY service but make sure you inform the user as well as Android OS by making it run on foreground with on going notification. it will help your service to run for long time without being killed by Android OS.

1 month is long period, user may reboot the cell in between. and you will need to restart your service. so you should register for reboot complete event . 

2.) I read that every app is a new user and separate VM is provided by the Android, question is when an app is considered to be closed?

There is no condition like considered to be closed.Actually, when user installs app, it is by default in stopped mode, it gets activated when user opens your app for first time. and application can go back to stopped mode again whenever user force stop your app.

3.) If my app closes, related services will also close then?

If you are considering that app is considered as closed when user don't use the app,your service won't close unless Android OS kills it in low memory situation.you may make it foreground as suggested earlier to convey Android OS that you are doing important things,nothing is wrong,so kill me only at last when you don't have any other options left
