花了不少的时间研究phonegap，希望能够找出一个能够取代轮询的推送方式，尝试了pushwoosh之后发现有两个问题，一个是手机必须集成有andriod apis的组件，其次不知道是不是什么原因总是有account失败的错误，实在是没有办法，想想即便解决了，第一个问题依然难以解决。

后来在江哥的推荐下找到了一个系统推送的phonegap插件

好了，首先我们来介绍一下用法：

1.(两个最关键的文件（.java和.js组件）)

var NotificationMessenger = { 
        notify:function(title, body) {
            return cordova.exec(null, null, 'StatusBarNotification','notify', [title, body]);
        },
        clear:function() {
            return cordova.exec(null, null, 'StatusBarNotification', 'clear', []);
        },
         
 
 
}

3.记得放入一张notification.png的图片在res下的drawable文件夹下

4.修改plugin.xml(添加一条记录)

<plugin name="StatusBarNotification" value="com.tricedesigns.StatusBarNotification"/>

5.定义调用的函数

function aaa(){
        NotificationMessenger.notify("CF西西", "Phonegap Andriod 交流 QQ 群 250395324欢迎您的加入");
    }

6.ok,找个按钮触发这个aaa函数，然后运行一下你会看到如下效果（项目代码可去我的qq群共享下载哦250395324）
