我正在使用firebase向我的应用发送通知.我想将每台设备上收到的通知保存在本地数据库中.问题是,当应用程序在后台并收到通知时,onMessageReceived()将不会调用该方法,而是根据文档将通知添加到系统托盘中.该文档还提到以下内容,以便在应用程序处于后台时收到通知:

在这些情况下,通知将传递到设备的系统托盘,并且数据有效负载将在启动器活动的附加内容中传递.

因此,当我尝试访问intent中的extras时,找不到通知的键.我的代码在MainActivity.java:

if (getIntent().getExtras() != null) {
        for (String key : getIntent().getExtras().keySet()) {
            Object value = getIntent().getExtras().get(key);
            Toast.makeText(this, "Key: " + key + " Value: " + value, Toast.LENGTH_LONG).show();
        }
    }

我们从服务器发送的通知:

{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
  "body" : "great match!",
  "title" : "Portugal vs. Denmark",
  "icon" : "myicon"
  }
}

任何人都知道如何检索通知中的值？

从Android P开始我的应用程序无法注册GCM ID.我的PushManager代码看起来像

try
        {
            GcmClient.CheckDevice(context);
            GcmClient.CheckManifest(context);
            String[] senderIds = GcmBroadcastReceiver.SENDER_IDS;
            foreach (String id in senderIds)
            {
                System.Diagnostics.Debug.WriteLine("sender id = " + id);
            }

            GcmClient.Register(context, senderIds);

            if (GcmClient.IsRegistered(context))
            {
                System.Diagnostics.Debug.WriteLine("push registration successfull: " +
                                                   GcmClient.GetRegistrationId(context));
            }
        }
        catch (Exception e)
        {
            System.Diagnostics.Debug.WriteLine("push registration failed: " + e.Message.ToString());
        }

我正在使用Firebase云消息传递API创建应用程序...我能够从服务器向我的客户端应用程序发送通知和数据.但问题是当应用程序打开时,通知不会在数据出现时触发(我的意思是我记录了它)这不是问题.但是当应用程序关闭时,会收到通知,而我点击通知时会打开活动,而我无法看到日志数据.我需要将数据更新为TextView ..

我的MyFirebaseMessagingService:

public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        Log.e("FROM", "From: " + remoteMessage.getFrom());
        String data = remoteMessage.getData().get("message");
        Log.e("KOIII", "Notification Message Body: …
