Android - 无法使用 FirebaseMessagingService 接收分组/捆绑通知

Question

我有一个 Firebase 服务，可以创建有关数据消息的通知。

它看起来像

public class KaliumMessagingService extends FirebaseMessagingService {
private static final String TAG = KaliumMessagingService.class.getSimpleName();
private static final String NOTIFICATION_CHANNEL_ID = "natrium_notification_channel";
private final String NOTIF_GROUP_ID = "NATRIUM_NOTIF_GROUP";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getData() != null && !MainActivity.appInForeground) {
sendNotification(remoteMessage);
}
}
@Override
public void onNewToken(String token) {
super.onNewToken(token);
SharedPreferencesUtil sharedPreferencesUtil = new SharedPreferencesUtil(this);
sharedPreferencesUtil.setFcmToken(token);
}
public void initChannels(Context context) {
if (Build.VERSION.SDK_INT < 26) {
return;
}
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,
getString(R.string.app_name),
NotificationManager.IMPORTANCE_HIGH);
channel.setDescription("Natrium transaction alerts");
notificationManager.createNotificationChannel(channel);
}
private void sendNotification(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
String amount = data.get("amount");
if (amount == null) {
return;
}
initChannels(this);
try (Realm realm = Realm.getDefaultInstance()) {
Credentials c = realm.where(Credentials.class).findFirst();
// If not logged in, shouldn't post notifications
if (c == null) {
return;
}
}
NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this,0,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setContentIntent(contentIntent);
builder.setSmallIcon(R.drawable.ic_status_bar);
builder.setContentText(getString(R.string.notification_body));
builder.setContentTitle(getString(R.string.notification_title, NumberUtil.getRawAsUsableString(amount)));
builder.setAutoCancel(true);
builder.setGroup(NOTIF_GROUP_ID);
builder.setSound(defaultSoundUri);
Notification pushNotification = builder.build();
nm.notify((int)System.currentTimeMillis(), pushNotification);
}
}

它可以工作，但是所有通知都是分开的。我希望它们都组合在一起/可扩展。单击它将打开主活动并关闭所有通知。

我以为setGroup会实现这种行为，但它似乎没有任何区别。

谢谢

我最终按照这篇博文中的描述解决了它
