How to detect user inactivity in Android

Question

User start my app and logs in.
Selects Session Timeout to be 5 mins.
Does some operations on the app. (all in foreground)
Now User bring Myapp to background and starts some other app.
----> Count down timer starts and logs out user after 5 mins
OR user turns the screen OFF.
----> Count down timer starts and logs out user after 5 mins

I want the same behavior even when the app is in the foreground but user doesn't interact with the app for a long-time say 6-7 mins. Assume the screen is ON all the time. I want to detect kind of user inactivity (No interaction with app even though the app is in the foreground) and kick start my count down timer.

There is no concept of "user inactivity" at the OS level, beyond the ACTION_SCREEN_OFF and ACTION_USER_PRESENT broadcasts. You will have to define "inactivity" somehow within your own application.
