Activitree/meteor-push: How to insert my Logo in Push Notification on smartphone?

Hey guys,

I have:
ph5app/startup/server/index,js with

defaults: {

imageUrl: ‘https://a_default_image_url.jpg’,

icon: ‘statusbaricon’, // String (name of icon for Android has to exist in app/src/res/…)


and file with my Logo:

Push Notification is sent to smartphone, but my Logo in Push Notification doesn’t shown.

What am I doing wrong? Any one know solutions, please tell me?
Thanks in advance
