本文实例讲述了AndroID编程实现Google消息通知功能。分享给大家供大家参考，具体如下：

1. 定义一个派生于WakefulbroadcastReceiver的类

public class GcmbroadcastReceiver extends WakefulbroadcastReceiver {  private static final String TAG = "GcmbroadcastReceiver";  @OverrIDe  public voID onReceive(Context context,Intent intent) {    Log.v(TAG,"onReceive start");    Componentname comp = new Componentname(context.getPackagename(),GcmIntentService.class.getname());    startWakefulService(context,(intent.setComponent(comp)));    setResultCode(Activity.RESulT_OK);    Log.v(TAG,"onReceive end");  }}

2. 用于处理broadcast消息的类

public class GcmIntentService extends IntentService {  private static final String TAG = "GcmIntentService";  public static final int NOTIFICATION_ID = 1;  private notificationmanager mnotificationmanager;  NotificationCompat.Builder builder;  private Intent mIntent;  public GcmIntentService() {    super("GcmIntentService");    Log.v(TAG,"GcmIntentService start");    Log.v(TAG,"GcmIntentService end");  }  @OverrIDe  protected voID onHandleIntent(Intent intent) {    Log.v(TAG,"onHandleIntent start");    Bundle extras = intent.getExtras();    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);    String messageType = gcm.getMessageType(intent);    if (!extras.isEmpty()) {      if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR          .equals(messageType)) {        sendNotification(extras.getString("from"),"Send error",extras.toString(),"",null,null);      } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED          .equals(messageType)) {        sendNotification(extras.getString("from"),"Deleted messages on server",null);      } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE          .equals(messageType)) {        Log.v(TAG,"BUNDLE SIZE = " + extras.size());        boolean sendreply = false;        String msgid = null;        for (String key : extras.keySet()) {          if ("gcm.notification.Title".equals(key)              || "gcm.notification.body".equals(key)              || "gcm.notification.click_action".equals(key)              || "gcm.notification.orderNumber".equals(key)) {            Log.v(TAG,"KEY=" + key + " DATA=" + extras.getString(key));          } else if ("gcm.notification.messageID".equals(key)) {            sendreply = true;            msgid = extras.getString(key);            Log.v(TAG,"KEY=" + key + " DATA=" + msgid);          } else {            Log.v(TAG,"KEY=" + key);          }        }        sendNotification(extras.getString("from"),extras.getString("gcm.notification.Title"),extras.getString("gcm.notification.body"),extras.getString("gcm.notification.click_action"),extras.getString("gcm.notification.orderNumber"),msgid);        Log.i(TAG,"Received: " + extras.toString());        mIntent = intent;        if (sendreply) {          new SendReceivedReply().execute(msgid);        } else {          GcmbroadcastReceiver.completeWakefulintent(intent);        }      }    } else {      GcmbroadcastReceiver.completeWakefulintent(intent);    }    Log.v(TAG,"onHandleIntent end");  }  private voID sendNotification(String from,String Title,String msg,String action,String ordernumber,String msgid) {    Log.v(TAG,"sendNotification start");    Log.v(TAG,"FROM=" + from + " title=" + Title + " MSG=" + msg        + " ACTION=" + action + " ORDERNUMBER=" + ordernumber);    mnotificationmanager = (notificationmanager) this        .getSystemService(Context.NOTIFICATION_SERVICE);    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(        this).setSmallicon(R.drawable.ic_launcher)        .setContentTitle(Title)        .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))        .setContentText(msg)        .setSound(Settings.System.DEFAulT_NOTIFICATION_URI);    PendingIntent contentIntent = PendingIntent.getActivity(this,new Intent(this,ActivitySplash.class),0);    mBuilder.setContentIntent(contentIntent);    if (ordernumber == null) {      mnotificationmanager.notify(NOTIFICATION_ID,mBuilder.build());    } else {      int n = ordernumber.charat(0);      String s = String.format(Locale.ENGliSH,"%d%s",n,ordernumber.substring(1));      n = Integer.valueOf(s);      Log.v(TAG,"NOTIF ID=" + n);      mnotificationmanager.notify(n,mBuilder.build());    }    GregorianCalendar c = new GregorianCalendar();    UtilDb.msgAdd(c.getTimeInMillis(),Title,msg,msgid);    Intent intent = new Intent(UtilConst.broADCAST_MESSAGE);    LocalbroadcastManager.getInstance(this).sendbroadcast(intent);    Log.v(TAG,"sendNotification end");  }  /*************************************************************/  /************************** ASYNCTASK ************************/  /*************************************************************/  private class SendReceivedReply extends AsyncTask<String,VoID,VoID> {    @OverrIDe    protected VoID doInBackground(String... params) {      if (params[0] != null) {        ArrayList<nameValuePair> nvp = new ArrayList<nameValuePair>();        nvp.add(new BasicnameValuePair("MessageID",params[0]));        UtilApp.dohttpPost(getString(R.string.url_base)            + getString(R.string.url_msg_send_received),nvp,null);      }      return null;    }    @OverrIDe    protected voID onPostExecute(VoID result) {      GcmbroadcastReceiver.completeWakefulintent(mIntent);    }  }}

服务器端（C#）：

public class GoogleNotificationRequestObj{  public IList<string> registration_IDs { get; set; }  public Dictionary<string,string> notification { get; set; }}private static ILog _log = LogManager.GetLogger(typeof(GoogleNotification));public static string CallGoogleAPI(string receiverList,string Title,string message,string messageID = "-1"){  string result = "";  string applicationID = ConfigurationManager.AppSettings["GcmAuthKey"];  WebRequest wRequest;  wRequest = WebRequest.Create("https://gcm-http.GoogleAPIs.com/gcm/send");  wRequest.Method = "post";  wRequest.ContentType = " application/Json;charset=UTF-8";  wRequest.headers.Add(string.Format("Authorization: key={0}",applicationID));  string postData;  var obj = new GoogleNotificationRequestObj()  {    registration_IDs = new List<string>() { receiverList },notification = new Dictionary<string,string>    {      {"body",message},{"Title",Title}    }  };  if (messageID != "-1")  {    obj.notification.Add("messageID",messageID);  }  postData = JsonConvert.SerializeObject(obj);  _log.Info(postData);  Byte[] bytes = EnCoding.UTF8.GetBytes(postData);  wRequest.ContentLength = bytes.Length;  Stream stream = wRequest.GetRequestStream();  stream.Write(bytes,bytes.Length);  stream.Close();  WebResponse wResponse = wRequest.GetResponse();  stream = wResponse.GetResponseStream();  StreamReader reader = new StreamReader(stream);  String response = reader.ReadToEnd();  httpWebResponse httpResponse = (httpWebResponse)wResponse;  string status = httpResponse.StatusCode.ToString();  reader.Close();  stream.Close();  wResponse.Close();  if (status != "OK")  {    result = string.Format("{0} {1}",httpResponse.StatusCode,httpResponse.StatusDescription);  }  return result;}
