Android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

package com.baofoo.manshenghuo.ui.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 com.baofoo.manshenghuo.MainActivity;
import com.baofoo.manshenghuo.R;
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){

4000
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
