Android：开机自启动并接收推送消息

接收推送消息部分我们通过ZeroMQ实现，可以参考http://www.cnblogs.com/ilovewindy/p/3984283.html。

首先是开机自启动的功能实现，代码如下：
1.    AndroidManifest.xml中添加如下代码：

 1 <!-- 抓取系统启动事件 --> 2 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 3  4 <application> 5 ….. 6     <service 7             android:name="com.demo.notification.NotificationService" 8             android:icon="@drawable/icon" 9             android:label="@string/app_name" >10     </service>11 12     <receiver android:name="com.demo.notification.MyScheduleReceiver" >13         <intent-filter>14             <action android:name="android.intent.action.BOOT_COMPLETED" />15         </intent-filter>16     </receiver>17 </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。

1 public class MyScheduleReceiver extends BroadcastReceiver {2 3     @Override4     public void onReceive(Context context, Intent intent) {5 6         Intent service = new Intent(context, NotificationService.class);7         context.startService(service);8     }9 }


3.    实现NotificationService代码，用来接收推送消息

 1 public class NotificationService  extends Service { 2     private final IBinder mBinder = new MyBinder(); 3  4     @Override 5     public int onStartCommand(Intent intent, int flags, int startId) { 6            // 将接收推送消息任务放入后台执行 7         new ZeroMQMessageTask().execute(); 8  9         return Service.START_STICKY;10     }11 12     @Override13     public IBinder onBind(Intent arg0) {14         return mBinder;15     }16 17     public class MyBinder extends Binder {18         public NotificationService getService() {19             return NotificationService.this;20         }21     }22 23     private class ZeroMQMessageTask extends AsyncTask<String, Void, String> {24 25         public ZeroMQMessageTask() {26         }27 28         @Override29         protected String doInBackground(String... params) {30 31             ZMQ.Context context = ZMQ.context(1);32             ZMQ.Socket subscriber = context.socket(ZMQ.SUB);33             subscriber.subscribe(ZMQ.SUBSCRIPTION_ALL);34             subscriber.connect("tcp://x.x.x.x:xxxx");35             while (true) {                  // 通过不终止的循环来保证接收消息36                 message = subscriber.recvStr();37                 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38 39                     // 显示推送消息40                     String ns = Context.NOTIFICATION_SERVICE;41                     NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);42 43                     int icon = R.drawable.icon;44                     CharSequence tickerText = "Demo - " + message;45                     long when = System.currentTimeMillis();46 47                     Notification notification = new Notification(icon,48                             tickerText, when);49                     notification.flags |= Notification.FLAG_AUTO_CANCEL;50                     Context uiContext = getApplicationContext();51                     CharSequence contentTitle = "Demo";52                     CharSequence contentText = message;53                     Intent notificationIntent = new Intent(uiContext,54                             NotificationService.class);55                     PendingIntent contentIntent = PendingIntent56                             .getActivity(uiContext, 0, notificationIntent, 0);57 58                     notification.setLatestEventInfo(uiContext, contentTitle,59                             contentText, contentIntent);60 61                     mNotificationManager.notify(1, notification);62                 }63             }64         }65 66         @Override67         protected void onPostExecute(String result) {68         }69     }70 }

好啦，重新启动手机尝试发条消息吧！ :D
