Java Android tracking usage time installation app

I need to track the usage time of all installed applications in the Android operating system. For example, this application is very similar: https://play.google.com/store/apps/details?id=com.agrvaibhav.AppUsageTracking

Is there any way to do this?

First, you can use android.app.activitymanager to retrieve mobile phone statues and running processes. A good example of this can be found here,

You can also monitor foreground activities to determine running tasks,
