首页 / 操作系统 / Linux / Android开机自启动并接收推送消息

首先是Android开机自启动的功能实现,代码如下:1. AndroidManifest.xml中添加如下代码:<!-- 抓取系统启动事件 -->
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /><application>
…..
    <service
            android:name="com.demo.notification.NotificationService"
            android:icon="@drawable/icon"
            android:label="@string/app_name" >
    </service>    <receiver android:name="com.demo.notification.MyScheduleReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
</application>2.    接着是实现MyScheduleReceiver代码,这是当Android启动后会自动启动的程序。public class MyScheduleReceiver extends BroadcastReceiver {    @Override
    public void onReceive(Context context, Intent intent) {        Intent service = new Intent(context, NotificationService.class);
        context.startService(service);
    }
}3.    实现NotificationService代码,用来接收推送消息public class NotificationService  extends Service {
    private final IBinder mBinder = new MyBinder();    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
         // 将接收推送消息任务放入后台执行
        new ZeroMQMessageTask().execute();        return Service.START_STICKY;
    }    @Override
    public IBinder onBind(Intent arg0) {
        return mBinder;
    }    public class MyBinder extends Binder {
        public NotificationService getService() {
            return NotificationService.this;
        }
    }    private class ZeroMQMessageTask extends AsyncTask<String, Void, String> {        public ZeroMQMessageTask() {
        }        @Override
        protected String doInBackground(String... params) {            ZMQ.Context context = ZMQ.context(1);
            ZMQ.Socket subscriber = context.socket(ZMQ.SUB);
            subscriber.subscribe(ZMQ.SUBSCRIPTION_ALL);
            subscriber.connect("tcp://x.x.x.x:xxxx");
            while (true) {                  // 通过不终止的循环来保证接收消息
                message = subscriber.recvStr();
                if (!message.equals("0")) {  // 0是由我自己定义的空消息标识,可以替换成自定义的其它标识                    // 显示推送消息
                    String ns = Context.NOTIFICATION_SERVICE;
                    NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);                    int icon = R.drawable.icon;
                    CharSequence tickerText = "Demo - " + message;
                    long when = System.currentTimeMillis();                    Notification notification = new Notification(icon,
                            tickerText, when);
                    notification.flags |= Notification.FLAG_AUTO_CANCEL;
                    Context uiContext = getApplicationContext();
                    CharSequence contentTitle = "Demo";
                    CharSequence contentText = message;
                    Intent notificationIntent = new Intent(uiContext,
                            NotificationService.class);
                    PendingIntent contentIntent = PendingIntent
                            .getActivity(uiContext, 0, notificationIntent, 0);                    notification.setLatestEventInfo(uiContext, contentTitle,
                            contentText, contentIntent);                    mNotificationManager.notify(1, notification);
                }
            }
        }        @Override
        protected void onPostExecute(String result) {
        }
    }
}好啦,重新启动手机尝试发条消息吧! :D服务器端的代码可以参考此文:http://www.linuxidc.com/Linux/2015-01/112318.htm相关阅读:在Ubuntu 11.04上安装ZeroMQ http://www.linuxidc.com/Linux/2011-07/38496.htmUbuntu Server 12.10 上安装 Node.js, ZeroMQ http://www.linuxidc.com/Linux/2012-11/73364.htmLinux下ZeroMQ write函数变更 http://www.linuxidc.com/Linux/2013-03/80272.htmZeroMQ使用注意点滴 http://www.linuxidc.com/Linux/2013-03/80273.htm更多Android相关信息见Android 专题页面 http://www.linuxidc.com/topicnews.aspx?tid=11本文永久更新链接地址:http://www.linuxidc.com/Linux/2015-01/112317.htm
