I am new to mobile push. Am trying to send a push notification to a test device. We configured the android app in the Admin section of Mobile push. When I try to do an outbound send, the mobile push expects a list/data extension of the Audience. What are the attributes it is expecting? The Salesforce documents nothing in detail on this.
Cant we not send a global push notification by sending the message to the app server itself and then the mobile app server decides to which all devices the message should be notified?
