当应用程序处于前台时未收到通知，单击通知时也未收到有效负载数据

Question

所以，我试图在应用程序处于后台或前台时收到通知，并尝试将数据有效负载从 firebase 控制台发送到 android 应用程序 activity，但我得到了这个

我在应用程序处于后台时收到通知
应用在前台时收不到通知
此外，我从 firebase 控制台获取的数据负载，密钥 "str"，未显示在 activity

请告诉我问题出在哪里，如何解决。

private static final String TAG = "FirebaseMessagingServic";

public FirebaseMessagingService() {
}

String value = "0";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        value = remoteMessage.getData().get("str"); //key text in quotes

    }
    String title = remoteMessage.getNotification().getTitle(); //get title
    String message = remoteMessage.getNotification().getBody(); //get message

    sendNotification(title, message, value);
    // Check if message contains a notification payload.
  /*  if (remoteMessage.getNotification() != null) {



        Log.d(TAG, "Message Notification Title: " + title);
        Log.d(TAG, "Message Notification Body: " + message);


    }*/
}

@Override
public void onDeletedMessages() {

}

private void sendNotification(String title,String messageBody, String value) {
    Intent intent = new Intent(this, CS101noti.class);
    SharedPreferences prefs = getSharedPreferences("MyApp", MODE_PRIVATE);
    prefs.edit().putString("body", value).apply();

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, 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(title)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

我已经解决了:)

您只需要从 REST API 或 Postman 发送数据负载，并在 Java 代码中获取数据值，它会像魅力一样工作:)

当应用程序处于前台时未收到通知，单击通知时也未收到有效负载数据

Not receiving notification when app is in foreground also not receiving payload data when clicking on notification

android

firebase
