        Log.d(TAG, "FRCM:"+ remoteMessage.getFrom());

         /*Check if the message contains data*/
        if(remoteMessage.getData().size() > 0){
            Log.d(TAG,"Message data: "+ remoteMessage.getData());

        }
        /*Check if the message contains notification*/
        if(remoteMessage.getNotification() != null){
            Log.d(TAG,"Message body: "+ remoteMessage.getNotification().getBody());
            sendNotification(remoteMessage.getNotification().getBody());


        }
    }
    /*Display Notification Body*/
    private void sendNotification(String body) {

        Intent intent = new Intent(this, Home.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0/*Request code*/, intent, PendingIntent.FLAG_ONE_SHOT);
        /*Set sound of Notification*/

        Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notifiBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_event_note_black_24dp)
                .setContentTitle("Firebase Cloud Messaging")
                .setContentText(body)
                .setAutoCancel(true)
                .setSound(notificationSound)
                .setContentIntent(pendingIntent);


        NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0/*ID of notification*/, notifiBuilder.build());
         intent = new Intent("myAction");
        intent.putExtra("title", title);
        intent.putExtra("message", message);
        LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }
}

和我的活动消息是。

public class Mess{
}

Answer 1

您使用FCM从手机发送消息。您需要使用要发送的有效负载生成POST到https://fcm.googleapis.com/fcm/send api，并在Firebase控制台项目中找到服务器密钥，或者您可以使用POSTMAN google chrome扩展

作为使用to param发送给单个用户的有效负载的exameple：

{ "data": {
      "score": "5x1",
      "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

此外，to param可用于主题"to": "topics/yourTopic"

在data中，您可以发送任何内容，并在Firebase的onMessageReceived()服务中收到消息。

您可以在Firebase documentation中找到更多详细信息。

用于将数据发送到其他活动

 private void sendNotification(String body) {

    Intent intent = new Intent(this, Home.class);

在这里你可以设置意图

 intent.putExtra("word", body);

并阅读活动使用

 b = getIntent().getExtras();
 String passed_from = b.getString("word");

如何从我的服务中获取数据或消息？
