Badge not appearing on application icon in a Launcher but notification came and is visible

My notification came and everything works perfectly, but my application icon does not have a badge.
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle(prepareTitleMessage(remoteMessage.getNotification()))
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true)
.setGroup(NOTIFICATION_CHANNEL)
.setContentIntent(pendingIntent)
.setDefaults(Notification.DEFAULT_SOUND)
.setVibrate(new long[]{1000, 1000})
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(remoteMessage.getNotification().getBody()));
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL, NOTIFICATION_CHANNEL_NAME, NotificationManager.IMPORTANCE_LOW);
channel.setShowBadge(true);
manager.createNotificationChannel(channel);
manager.notify(requestCode, notificationBuilder.build());

Android notification sound doesn't work

var notificationBuilder = new Notification.Builder(context)
.SetSmallIcon(Resource.Drawable.Icon)
.SetLargeIcon(BitmapFactory.DecodeResource(Application.Context.Resources, Resource.Drawable.Icon))
.SetContentTitle(title)
.SetContentText(message)
.SetAutoCancel(true)
.SetContentIntent(pendingIntent)
.SetStyle(new Notification.BigTextStyle().BigText(message))
.SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetVibrate(new long[] { 1000, 1000 })
.SetDefaults(NotificationDefaults.All);
var notificationManager = (NotificationManager)context.GetSystemService(Context.NotificationService);
notificationManager.Notify(0, notificationBuilder.Build());
Where i was wrong? Why my notifications doesn't have any sound or vibration?

Remove .SetDefaults(NotificationDefaults.All), you are resetting the notification settings that you just built:
var notification = new Notification.Builder(Application.Context)
.SetSmallIcon(Resource.Mipmap.Icon)
.SetLargeIcon(BitmapFactory.DecodeResource(Application.Context.Resources, Resource.Mipmap.Icon))
.SetContentTitle("Stack")
.SetContentText("OverFlow")
.SetAutoCancel(true)
//.SetContentIntent(pendingIntent)
.SetStyle(new Notification.BigTextStyle().BigText("OverFlow"))
.SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetVibrate(new long[] { 1000, 1000 })
.Build();
var notificationManager = (NotificationManager)Application.Context.GetSystemService(Context.NotificationService);
notificationManager.Notify(1, notification);

Try passing uri to setSound in notificationBuilder like this
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationBuilder.setSound(uri);

Android Push Notification: Style doesn't work when application is closed or killed

NotificationCompat.InboxStyle notifInbox = new NotificationCompat.InboxStyle();
notifInbox.addLine("First Word");
notifInbox.addLine("Second Word");
notifInbox.addLine("Third Word");
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notificon)
.setContentTitle(title)
.setSubText("FROM: SYSTEM")
.setContentInfo("X")
.setStyle(notifInbox)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
Why is it when my application is closed or killed, then I send a notification, the style doesn't work? Or how to prevent the notification to show when the application closed or killed? I'm using FCM. Any help is appreciated.

It's working for me you can try it.
if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP){
// Do something for lollipop and above versions
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setPriority(Notification.PRIORITY_HIGH)
.setContentTitle(TextUtils.isEmpty(title) ? "XYZ" : title)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg)
.setColor(getResources().getColor(R.color.colorPrimary));
mBuilder.setSound(Uri.parse("content://settings/system/notification_sound"));
mBuilder.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
mBuilder.setAutoCancel(true);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
} else {
// do something for phones running an SDK before lollipop
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(TextUtils.isEmpty(title) ? "xyz" : title)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg);
mBuilder.setSound(Uri.parse("content://settings/system/notification_sound"));
mBuilder.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
mBuilder.setAutoCancel(true);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

Notification setStyle is not working in lollipop

I'm stuck in notificaion.
When I run below code under lollipop and over lollipop, it works fine.
However, if I run codes in lollipop, setstyle() method is not working.
I also tried with remoteviews, but it also not work.
I tried with BigPicture ,but it also doesn't work.
What did I miss?
Please help.
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(largeIcon)
.setContentTitle(title)
.setContentText(content)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setAutoCancel(true)
.setVibrate(new long[]{1000, 1000, 1000})
.setSound(defaultSoundUri)
.setStyle(new NotificationCompat.BigTextStyle().bigText(content))
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
I tried with many devices and found that it happens in android version 5.0.2.

I don't find any problem except setContentText() remove it and give a try to the following :
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(largeIcon)
.setContentTitle(title)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setAutoCancel(true)
.setVibrate(new long[]{1000, 1000, 1000})
.setSound(defaultSoundUri)
.setStyle(new NotificationCompat.BigTextStyle().bigText(content))
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

CWAC updater issue with notification

I'm using this library https://github.com/commonsguy/cwac-updater to provide feature of auto update for an app.
I read the demoUpdater it uses a deprecated API for Notification, so I used the following code:
ConfirmationStrategy buildPreDownloadConfirmationStrategy(Context mContext) {
long[] vibrate = { 0, 100, 200, 300 };
NotificationManager mNotificationManager= (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(mContext)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Update Available")
.setContentText("Click to download the update!")
.setVibrate(vibrate)
.setAutoCancel(true)
.setLights(Color.BLUE, 500, 500);
mNotificationManager.notify(1, mBuilder.build());
return null;
//return(new NotificationConfirmationStrategy());
}
but can't get it working.

I got it working, If anyone finds trouble then use below code
ConfirmationStrategy buildPreDownloadConfirmationStrategy(Context mContext) {
long[] vibrate = { 0, 100, 200, 300 };
NotificationManager mNotificationManager= (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(mContext)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Update Available")
.setContentText("Click to download the update!")
.setVibrate(vibrate)
.setAutoCancel(true)
.setLights(Color.BLUE, 500, 500);
Notification notification = mBuilder.build();
mNotificationManager.notify(1, notification);
return(new NotificationConfirmationStrategy(notification));
}
