android消息推送

网上搜索到如下类似文章,经调试可行后改成自己的代码再发上来记录一下

独立进程 
无论程序是否正在运行，我们都要能通知到客户，我们需要一个独立进程的后台服务。 
我们需要一个独立进程的后台服务。 
在androidmanifest.xml中注册service时，有一个android:process属性，如果这个属性以"."开头，则为此服务开启一个 
全局的独立进程，如果以":"开头则为此服务开启一个为此应用私有的独立进程。举个具体的例子吧，我们新建了一个 
application,创建了主进程com.example.exerciseproc，那么： 

<!--下面会创建一个全局的com.example.exerciseproc的独立进程--> 

 <service android:name="com.example.exerciseproc.MessageService" android:label="消息推送" android:process=".message"/>

<!--或者--> 
<!--下面会创建一个应用私有的com.cnblogs.tianxia:message的独立进程--> 

 <service android:name="com.example.exerciseproc.MessageService" android:label="消息推送" android:process=":message"/>

通知用户和点击查看

在Activity中启动服务

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
                 
          Log.d("消息服务", "正在启动消息推送服务");
          startService(new Intent(this,MessageService.class));
    }
