set Default Notification Accent Color
This integer sets the default accent color for push notifications on Android Lollipop and higher. If not specified, the default background color is gray (the same gray Lollipop uses for system notifications). This value can be overridden at runtime by a push notification that sets a custom accent color.
Hexadecimal is a valid input for the color, i.e. "0xFFf33e3e".
Defaults to Notification.COLOR_DEFAULT.
Parameters
default Notification Accent Color
the integer color value for the default notification accents.
