Get running Intent Service

Hi,

I'm creating an android application that will do a task in a specific time (defined by the user). For this I'm using an Intent Service.

The the problem is if the user closes the application (example: using back button) then I cannot get the the running service to shutdown it, to read information from it (to update my activity when the application opens), etc.

Is this the better approach?

Is there any way to get the running service (intent service)?

Thanks

When the user closes your activity the onStop() method of the activity is called (or the onPause(), depending on what made the activity stop). So you could implement your code in one of these two methods.

Thanks for the reply.

But the second time the user presses the back button it destroys the activity and the next time it opens, it starts  a new instance.

What I want to achieve is to check if the service is already running. If not, then start a new one, if it's running, then get the state of the timer, selected options, etc, and event shutdown the service (if the user wants it).

You are right, when the user presses the back button your current activity will be destroyed. So when you start your activity again it will be a new instance. You cannot check if your activity is running since there is no activity. I guess what you need to do is to recreate the activity state when the onCreate() method is called (when you start a new activity). You will need to save your activity state in method onSaveInstanceState() and then recreate it by reading the data from the bundle. For more information have a look here.
