Android notification icon is a white circle.

Question

Today I have a strange problem with the notification icon.

It looks like this: (white circle ...)

Did I do something bad?

Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.icon_notification)
                .setContentTitle(this.getString(R.string.notification_title))
                .setContentText(this.getString(R.string.notification_text))
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

Here is my icon image (just downloaded here https://material.io/icons/#ic_photo ): http://image.noelshack.com/fichiers/2016/44/1478185219-icon-notification.png

Did I miss something?

For recording, I use SDK 24 and just created a resource folder hdpi.

Edit # 1: I added icons ldpi, mdpiand xhdpi, nothing has changed ...

Edit # 2: For more accuracy, I'm trying to create this notification from a service ... FCM Messaging Service ...

Note. You need to upload a PNG image of your icon with a transparent background.

U installation icon may have this method

private int getSmallIconForNotification(){
    return (Build.VERSION.SDK_INT>Build.VERSION_CODES.LOLLIPOP)? R.mipmap.ic_stat_launcher : R.mipmap.ic_launcher;
}

Code Usage:

private NotificationCompat.Builder createNotificationBuilder(){
    return new NotificationCompat.Builder(this)
            .setSmallIcon(getSmallIconForNotification())
            .setContentTitle("New Message")
            .setContentText("Hi there.....")
            .setAutoCancel(true);
}
