How do I restart the app when it’s brought from the background?

I need my app to reboot whenever it’s brought from the OS background, so the user is forced to log in again.

I tried to use the finishAffinity() in my onPause() of Activity, the problem is that this method is also called when there is a transition between activities, causing when the OnBackPressed if the application were to restart as well.

If there is no other solution, use a flag to indicate when to do Finish.

As I understand it just should not happen when it returns from an Activity launched by her.

Declare the flag as an attribute

Boolean canFinish = true;

When to launch Activity

canFinish = false;
startActivity(....);

In the method onPause()

if(canFinish){
    finishAffinity()
}else{
    canFinish = true;
}

I assume that finishAffinity() does what you intend and should be done in the onPause().
