Android实现系统消息推送

现在好多应用都接入了推送功能，市面上也有很多关于推送的第三方，例如极光等等，那么我们需求不大，接入极光会造成很大的资源浪费，下面我们来看下利用android服务进行本地推送消息。

1.注册一个service

import android.annotation.targetapi;
import android.app.notification;
import android.app.notificationmanager;
import android.app.pendingintent;
import android.app.service;
import android.content.context;
import android.content.intent;
import android.os.build;
import android.os.ibinder;
import java.util.calendar;
 
/**
 * created by 70883 on 2017/8/10.
 */
public class pushsmsservice extends service {
 private notificationmanager manager;
 private pendingintent pi;
 private mythread mythread;
 @override
 public ibinder onbind(intent intent) {
  // todo auto-generated method stub
   return null;
   }
 
 @override
 public void oncreate() {
  mythread = new mythread();
  mythread.start();
  super.oncreate();
 }
 
 @override
 public void ondestroy() {
  super.ondestroy();
 }
   @targetapi(build.version_codes.jelly_bean)
   private void notification() {
    // 获取系统的通知管理器 
    manager = (notificationmanager) getsystemservice(context.notification_service);
    intent intent = new intent(getapplicationcontext(),
      mainactivity.class);
    pi = pendingintent.getactivity(getapplicationcontext(), 0, intent, 0);
    notification notification = new notification.builder(getapplicationcontext())
      .setautocancel(true)
      .setcontenttext("工作在忙,也要吃饭哦")
      .setcontentintent(pi)
      .setsmallicon(r.mipmap.ic_icon)
      .setwhen(system.currenttimemillis())
      .build();
    notification.defaults = notification.default_all; // 使用默认设置，比如铃声、震动、闪灯 
     notification.flags = notification.flag_auto_cancel; // 但用户点击消息后，消息自动在通知栏自动消失 
    notification.flags |= notification.flag_no_clear;// 点击通知栏的删除，消息不会依然不会被删除 
    manager.notify(0, notification);
   }
 private class mythread extends thread{
  private calendar c ;
  @override
  public void run() {
   while (true){
    c = calendar.getinstance();
    if(c.get(calendar.hour_of_day) == 15){
      try {
       notification();
       sleep(1000*60*60);
      } catch (interruptedexception e) {
       e.printstacktrace();
      }
    }
   }
 
  }
 }
}

2.在androidman中注册

<service android:name=".ui.service.pushsmsservice"></service>

3.由于我是需要全局应用就在application中进行启动了 

public void startservice() {
  intent intent = new intent(this, pushsmsservice.class);
  // 启动服务
  startservice(intent);
 }

4.也可以配合服务端使用，定时推送消息
