下面是我项目里面使用到的结束整个应用，退出所有Activity 包括服务:

import java.util.LinkedList;
import java.util.List;

import android.app.Activity;
import android.app.Application;

public class MyApplication extends Application {

	private List<Activity> activityList = new LinkedList<Activity>();
	private static MyApplication instance;

	private MyApplication() {
	}

	// 单例模式中获取唯一的MyApplication实例
	public static MyApplication getInstance() {
		if (null == instance) {
			instance = new MyApplication();
		}
		return instance;
	}

	// 添加Activity到容器中
	public void addActivity(Activity activity) {
		activityList.add(activity);
	}

	// 遍历所有Activity并finish
	public void exit() {
		new MyCommonDialog("正在保存数据..") {
			@Override
			protected String doNoUiOpt() {
				// TODO Auto-generated method stub
				for (Activity activity : activityList) {
					activity.finish();
				}
				return super.doNoUiOpt();
			}

			@Override
			protected void doBack(String success) {
				// TODO Auto-generated method stub
				System.exit(0);
				super.doBack(success);
			}
		};

	}

}

读者可以在exit() 方法中直接使用： for (Activity activity : activityList) {activity.finish();}return super.doNoUiOpt(); System.exit(0);

MyCommonDialog这个类是我自定义的提示类，可以直接去掉。
