Android user activity detection

I would like to know when the last time the user interacted with the screen. I am not interested in doing any malicious / spyware programs, I just need to calculate how much time has passed since the user last clicked on the screen.

The goal is to achieve functionality similar to the key lock function.

I did some research and followed some of the Q & A on the site (e.g. Android. The best way to detect and handle user INACTIVITY , Android: detecting general user usage among others), but when it comes to detecting user interaction in android, I don’t found what i need.

Thanks in advance.

After several studies and trials, I managed to get up with a solution.

What I did was create a background service in which I get an instance of WindowManager and add a view of zero size that receives a notification of the user touching outside of it ... but since the view is of zero size, it can be called every time. To do this, we can check https://developer.android.com/reference/android/view/WindowManager.LayoutParams.html

        return null;
