I am trying to write a program in Android studio and would like to detect OnUserLeaveHint. My code currently works, but it is also called when I click on a button to move to another activity.

How can I make it in such a way that the method is only called when the app is minimized or closed and not when a button is clicked to open another activity?

When HOME button is pressed, this is the flow: 

onUserLeaveHint()
onPause()
onSavedInstanceState()
onStop()

When transitioning from Activity A to Activity B, this is the flow:

onUserLeaveHint()  (of Activity A)
onPause()  (of Activity A)
onApplyThemeResource  (of Activity B)
onCreate  (of Activity B)
onStart (of Activity B)
onResume  (of Activity B)
onSavedInstanceState()  (of Activity A)
onStop()  (of Activity A)

You need to understand there is no official way to listen to HOME button taps. There are few workaround solutions which seems to work for most of the case but not a 100% concrete solution. What you can do is, use one of the solution to listen to HOME press and turn on a flag. Then use this flag value to differentiate if its a HOME press or Activity change.
