## 推送原理 ##

- xmpp 是一种基于TCP/IP的协议, 这种协议更适合消息发送
- socket 套接字, 发送和接收网络请求
- 长连接 keep-alive, 服务器基于长连接找到设备,发送消息
- 心跳包 , 客户端会定时(30秒一次)向服务器发送一段极短的数据,作为心跳包, 服务器定时收到心跳,证明客户端或者,才会发消息.否则将消息保存起来,等客户端活了之后(重新连接),重新发送.

> 客户端轮询(客户端定时主动拉取数据), 浪费流量, 浪费性能

MainActivity.java

package com.ldw.push;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        //使用自定义的application        MyApplication application = (MyApplication) getApplication();application.doSomething();    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }    }

自定义Application来取代系统Application MyApplication.java

package com.ldw.push;import android.app.Application;import cn.jpush.android.api.JPushInterface;/* * 自定义application */public class MyApplication  extends Application{@Overridepublic void onCreate() {super.onCreate();System.out.println("应用创建啦....");JPushInterface.setDebugMode(true);    JPushInterface.init(this);}public void doSomething() {System.out.println("do something...");}}

自定义广播接收者PushReceiver.java

package com.ldw.push;import org.json.JSONException;import org.json.JSONObject;import cn.jpush.android.api.JPushInterface;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.util.Log;public class PushReceiver extends BroadcastReceiver{private static final String TAG = "PushReceiver";@Overridepublic void onReceive(Context context, Intent intent) {Bundle bundle = intent.getExtras();Log.d(TAG, "onReceive - " + intent.getAction());if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {} else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {System.out.println("收到了自定义消息。消息内容是："+ bundle.getString(JPushInterface.EXTRA_MESSAGE));// 自定义消息不会展示在通知栏，完全要开发者写代码去处理} else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {System.out.println("收到了通知");// 在这里可以做些统计，或者做些其他工作} else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {System.out.println("用户点击打开了通知");// 在这里可以自己写代码去定义用户点击后的行为String extra = bundle.getString(JPushInterface.EXTRA_EXTRA);System.out.println("附加信息:" + extra);try {JSONObject jo = new JSONObject(extra);String url = jo.getString("url");System.out.println("url:" + url);// 跳浏览器加载网页} catch (JSONException e) {e.printStackTrace();}}}}
