Android Application: Run code on a timer from the background

hello everyone and thank you in advance. My problem is that I have an app that the user will start in the foreground and will set a variable as a timer. The user will most likely close that app, or the phone will go to sleep. So I need the app to background and then run code to send a notification when that timer hits 0.

For the timer I would use unix time and have the background process check to see if it matched or the current time surpassed when the timer goes off.

I would like to know - A) how to send the app to the background with these instructions B) how to then foreground the app, or at least be able to send a notification after running some code

Again, thank you very much, let me know if I was not clear or if I missed someone's previous thread.

Look at extending the Android Handler class to create a custom Handler that creates a notification when the Handler receives a Message that you send it using the method sendMessageAtTime(android.os.Message, long uptimeMillis) or sendMessageDelayed(android.os.Message, long delayMillis). When that timer went off could be specified using the long parameter of either of those methods.

Hope this helped!

This post should be a good place to start, it looks like what you want to use is a service.
