How to set default smallIcon and largeIcon in an Android notification received?

Question

I'm actually using PushBots to implement GCM notifications for my application.

They give me the option, when I create the notification, to use a specific field where I can set the largeIcon for my push. If I use that, I get something like this:

But, if I dont use that, I get this:

I would like to know if is it possible to set a default smallIcon and largeIcon for every notification (push) that my app recieve or change that white box that appears for my own app icon.

1- Note: I don't create the notification in my code, I create it in the PushBots website Drashboard.

2- Note: largeIcon and smallIcon

Thanks.

Finally, after hours looking the source code of PushBots, I just found out a solution.

In Android Studio, go to File -> New -> Image Asset. Then, choose Notification Icon. Now customize your new small Icon and, before finish it, put the name white_notification_icon for this new asset.

Android Studio will say to you that the file already exists and it is going to be overwritten. Say yes.

Now, you have a smallIcon by default already set!

Please refer following code

   NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
    mBuilder.setSmallIcon(R.drawable.small_notification);
    mBuilder.setLargeIcon(BitmapFactory.decodeResource(getBitmapFromURL("YOURURL"));

    if (version >= 23) {
        mBuilder.setColor(ContextCompat.getColor(this, R.color.black));
    } else {
        mBuilder.setColor(this.getResources().getColor(R.color.black));
    }

As per guide line small icon is compulsory and should be in white color or in gray color with alpha back ground refer this answer for more details

go to link specified in this answer and get the entire function for notification – Vishal Mokal May 13 '16 at 23:58
Your answer will solve the problem if I would create the notifications from the code, but i dont do that. There is the problem, I just want to set a smallIcon and a largeIcon for every notification that I recieve, not that I create. – David Corral May 14 '16 at 08:10
do you want it it only for your application or for all application on device – Vishal Mokal May 16 '16 at 05:56
