PushNotification not working with the app in background

问题

I'm developing an iOS and android app using ionic/cordova, and I'm trying to get the push notifications working on both platforms with the PushPlugin library.

The thing is I'm getting the push notifications working OK for iOS, but in android is a little weird what is going on, when the app is in foreground, the notification arrives successfully, but when the app is in background (the app is close), the notification never arrives...

Any thoughts about this? Permissions?

I followed this tutorial for getting the gcm notifications working (my code is similar) and also I'm testing the notifications with genymotion.

Here's my AndroidManifest.xml

<?xml version='1.0' encoding='utf-8'?>

Try to look if you are sending the notification payload with this structure:

{
   message : "message"
}
