Push Notification Icon Android

How can i set an icon for push notification on android. Or in other words where should my icon be placed in order to read it.
In my app.modules I have the following:

const cloudSettings: CloudSettings = {
‘core’: {
‘app_id’: ‘xxxxx’,
‘push’: {
‘sender_id’: ‘xxxxx’,
‘pluginConfig’: {
‘ios’: {
‘badge’: true,
‘sound’: true
‘android’: {
‘iconColor’: ‘#cc287a’,
‘icon’: ‘icon’

iconColor is working perfectly but icon is always blank. Any solution?
