Changing notification icon background on Lollipop
1) Obtain Color
int color = 0xff123456;int color = getResources().getColor(R.color.my_notif_color);int color = ContextCompat.getColor(context, R.color.my_notif_color);2) Set the Color to the Notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);...builder.setColor(color);Notification notif = builder.build();The color is respected only on Lollipop and only affects background of the small icon. If a large icon is shown its contents are entirely your responsibility.
if you've defined color in colors.xml then in your NotificationBuilder add value as
.setColor(getResources().getColor(R.color.<YOUR_COLOR>))That should solve your problem. It only affect to background of the icon.
getColor(int) has been deprecated on Resources
We should now use one of these alternatives:
Resources's getColor(int, Theme)ContextCompat's getColor(Context context, int id)
