android.app.RemoteServiceException: Bad notification for startForeground

I'm trying to start foreground service as follow:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

    NotificationChannel chan = new NotificationChannel(
            getApplicationContext().getPackageName(),
            "My Foreground Service",
            NotificationManager.IMPORTANCE_LOW);
    chan.setLightColor(Color.BLUE);
    chan.setLockscreenVisibility(Notification.VISIBILITY_SECRET);

    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    assert manager != null;
    manager.createNotificationChannel(chan);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder( 
            this, "MyChannelId");
    Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.my_icon)
            .setContentTitle("App is running on foreground")
            .setPriority(NotificationManager.IMPORTANCE_LOW)
            .setCategory(Notification.CATEGORY_SERVICE)
            .setChannelId("MyChannelId")
            .build();

    startForeground(1, notification);
}

This solution works for Android 8.0 Emulator. But I got the error below on Android 8.1, 9.0 and 10.0 Emulator.

android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=MyChannelId pri=2 contentView=null vibrate=null sound=null defaults=0x0 flags=0x42 color=0x00000000 category=service vis=PRIVATE)

PS: I tried on a non-emulator Android 9.0 device and didn't get this error.

Issue is happening because you are creating a channel with an ID but sending the notification in a different ID:

// Here, you are using the package name as channel ID
NotificationChannel chan = new NotificationChannel(
              getApplicationContext().getPackageName(), 
              "My Foreground Service",
              NotificationManager.IMPORTANCE_LOW);

// But here, you are sending notifications to "MyChannelId"
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder( 
              this, "MyChannelId");

So, I believe you just need to change Channel ID to MyChannelID as follows:

NotificationChannel chan = new NotificationChannel(
              "MyChannelId",
              "My Foreground Service",
              NotificationManager.IMPORTANCE_LOW);
