Answer 1

The documentation states:

A notification's big view appears only when the notification is expanded, which happens when the notification is at the top of the notification drawer, or when the user expands the notification with a gesture.

So my answer is no, you can't expand it by default.

There is however a trick to push the notification to the top of the list where it would be expanded. Simply set the Priority to Notification.PRIORITY_MAX and chances are that your app's notification will make it to the top.
