You have to use icon from res/drawable folder for setSmallIcon().

But in API23, you can use bitmap

    setSmallIcon(Icon.createWithBitmap(bitmap))

Setting bitmap as small icon is available from android M and cannot be used in lower versions.

first you have to check if version is above M or not.

if it's bellow you should use NotificationCompat.Buidler

if it's above android M you should use Notification.Builder

in Notification.Buidler you have a method called setSmallIcon(Icon) that can be uses like this.

builder.setSmallIcon(Icon.createFromBitmap(bitmap));

so if you really need this feature& you only can use it in api level 26 and above.
