How do I test for activity inactivity time

Question

Hello, I'm wondering what is the highest level I can go in-order to know when the user interacts with my application

preface: I'd like to logout of my application after X seconds of user inactivity. so what I did is create a service with a timer, and a toggle function which resets the timer to X time. after X time has passed, an intent is raised, and a broadcast receiver catches that intent and preforms the logout (closing the open logged in activities as well...)

as for the actual question, I need to call the "Timer Toggle" function each time the user interacts with the application. where is the highest place in the android app that I can know when the user interacts with the phone

The only thing I found is to implement onClick and onKeyPress for each activity, is there another better way? maybe in the Application class?

I don't think there's any other way aside from sending events from the Activity itself.
You could look at overriding Activity.onUserInteraction().

But is it likely that the user will be in a single Activity of your application for "X seconds" without ever switching screens, or letting the device go into sleep?

I imagine it would be sufficient to update the timer/flag in onCreate, onPause and onResume. Plus maybe some commonly-called functions within the Activity.
