"Android" exits the program anytime, anywhere

Create a new Activitycollector class as the activity manager, as shown in the following code:
public class Activitycollector {
public static list<activity> activities = new arraylist<activity> ();
public static void addactivity (activity activity) {
Activities.add (activity);
}
public static void removeactivity (activity activity) {
Activities.remove (activity);
}
public static void Finishall () {
for (Activity activity:activities) {
if (!activity.isfinishing ()) {
Activity.finish ();
}
}
}
}
In the activity manager, we staged the activity through a list, and then provided a addactivity () method to add an activity to the list, provided a removeactivity () method to remove the activity from the list, and finally provided a The Finishall () method is used to destroy all the activities stored in the list.

To exit all programs, you only need to call Activitycollector.finishall ().
