	ActivityManager activityManager = context.getSystemService(ActivityManager.class);
	//获取任务栈列表
	List tasks = activityManager.getAppTasks();
	for (ActivityManager.AppTask task : tasks) {
	    ActivityManager.RecentTaskInfo info = task.getTaskInfo();
	    int activityCount = info.numActivities; //栈内Activity数量
	    String topActivity = info.topActivity.getClassName(); //栈顶Activity
	    String baseActivity = info.baseActivity.getClassName(); //栈底Activity
	    task.setExcludeFromRecents(true); //不显示在最近任务列表中
	    task.finishAndRemoveTask(); //销毁任务栈内全部Activity
