如何在特定时间发送Firebase通知？

本文介绍了如何在特定时间发送Firebase通知？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我试图安排特定时间，并希望使用Firebase发送通知。我正在进行项目，在比赛开始前我必须发送通知。目前我的通知正在实时工作，但我找不到任何方法来安排它的具体时间。

对于实时我使用这个特定的代码。

// Class扩展服务，因为它是一个后台运行的服务 public class NotificationFirebaseListener extends FirebaseMessagingService { private static final String TAG =MyFirebaseMsgService; 字符串测试; $ b @Override public void onMessageReceived（RemoteMessage remoteMessage）{ Log.e（TAG，From：+ remoteMessage.getFrom（） ）; Log.e（TAG，Notification Message Body：+ remoteMessage.getNotification（）。getBody（）+=====>）; （remoteMessage.getData（）。size（）> 0）{ Log.e（TAG，Message data payload：+ remoteMessage.getData（））; 。 test = String.valueOf（remoteMessage.getData（））; } sendNotification（test）; private void sendNotification（String messageBody）{ Intent intent = new Intent（this，MainActivity.class）; intent.addFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）; PendingIntent pendingIntent = PendingIntent.getActivity（this，0，intent， PendingIntent.FLAG_ONE_SHOT）; Uri defaultSoundUri = RingtoneManager.getDefaultUri（RingtoneManager.TYPE_NOTIFICATION）; NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder（this） .setSmallIcon（R.mipmap.ic_launcher） .setContentTitle（Bus Tracking） .setContentText（messageBody） .setAutoCancel（true） .setSound（defaultSoundUri） .setContentIntent（pendingIntent）; NotificationManager notificationManager = （NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）; notificationManager.notify（0，notificationBuilder.build（））; $ b

解决方案实现此目的的最佳方式是使用Firebase通知撰写程序为您的应用程序安排通知： firebase.google/docs/notifications/

如果您想通过另一种方式实现这些代码，我建议您使用ScheduledThreadPool来安排您的通知。您可以在oracle文档中阅读更多关于此的信息： docs.oracle/javase/7/docs/api/java/util/concurrent/ScheduledThreadPoolExecutor.html

祝您好运！ / p>

I am trying to schedule particular time and want to send notification using Firebase. I am working on the project where I have to send the notification before the match start. Currently my notification is working on real time but I can't found any way to schedule it for the specific time.

For the real time I am using this particular code.

//Class extending service as it is a service that will run in background public class NotificationFirebaseListener extends FirebaseMessagingService { private static final String TAG = "MyFirebaseMsgService"; String test; @Override public void onMessageReceived(RemoteMessage remoteMessage) { Log.e(TAG, "From: " + remoteMessage.getFrom()); Log.e(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody() + "=====>"); if (remoteMessage.getData().size() > 0) { Log.e(TAG, "Message data payload: " + remoteMessage.getData()); test = String.valueOf(remoteMessage.getData()); } sendNotification(test); } private void sendNotification(String messageBody) { Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.mipmap.ic_launcher) .setContentTitle("Bus Tracking") .setContentText(messageBody) .setAutoCancel(true) .setSound(defaultSoundUri) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0, notificationBuilder.build()); } }

解决方案

The best way to achieve this is use the Firebase Notification composer to schedule your notifications for your app: firebase.google/docs/notifications/

If you want another way to achieve these via code, I suggest you to schedule your notification using a ScheduledThreadPool. You can read more about this in the oracle documentation: docs.oracle/javase/7/docs/api/java/util/concurrent/ScheduledThreadPoolExecutor.html

Good luck!
