Android push notifications custom icon.

Hi, im using pushwoosh for push notifications on android. The only problem is that i can’t use my custom icon, I only get the triangle with exclamation mark. Ive added the list of resources that says in the docs, but no difference.

I dont know if there is something wrong with my files or is there something else i have to do?

Thanks
