本文介绍了一个公共类ExitApplication，它提供了一个方法来在退出应用时批量关闭所有Activity，确保资源的有效释放。

public class ExitApplication extends Application{

private List<Activity> activitys = new LinkedList<Activity>();
private static ExitApplication instence;
private UserData loginUser ;
private ExitApplication(){
}
//获得ExitApplication实例
public static ExitApplication getInstence() {
if(null == instence){
instence = new ExitApplication();
}
return instence;
}
//添加activity到list
public void addActivity(Activity activity){
if(!activitys.contains(activity)){
activitys.add(activity);
}

}
//退出时杀掉所有Activity
public void exit(){
if(!activitys.isEmpty()){
for(Activity activity :activitys){
activity.finish();
}
}
System.exit(0);
}
public UserData getLoginUser() {
return loginUser;
}
public void setLoginUser(UserData loginUser) {
this.loginUser = loginUser;
}

}
