what is the right way to clear background activity/activites from stack?

Question

as the questions title says - I need to know what is the best way to \"remove\"/destroy/finish an activity that are somewhere in the middle of stack and currently on pause

Answer 1

I also had the same problem. What I did is, I kept a static array list, and whenever I used to go from one activity to another, in the onCreate() method of new activity, I added the object of current activity into that list like this:

SomeClass.addActivity(CurrentActivity.this);

I added the above statement in each activity.

The addActivity():

public void addActivity(final Activity activity) {
            activityList.add(activity);
        }

And when I wanted to clear the stack, I called:

public boolean clearStack() {
        for (Activity activity : activityList) {
            activity.finish();
        }
        activityList.clear();
        return (activityList.isEmpty());
    }

In this way, I cleared my activity stack.

Thank you :)
