### Method Details

`close()`

    Close httplib2 connections.

`list(parent, pageSize=None, pageToken=None, x__xgafv=None)`

    List aggregate delivery data for the given Android application.

    Args:
      parent: string, Required. The application for which to list delivery data. Format: `projects/{project_id}/androidApps/{app_id}` (required)
      pageSize: integer, The maximum number of entries to return. The service may return fewer than this value. If unspecified, at most 1,000 entries will be returned. The maximum value is 10,000; values above 10,000 will be capped to 10,000. This default may change over time.
      pageToken: string, A page token, received from a previous `ListAndroidDeliveryDataRequest` call. Provide this to retrieve the subsequent page. When paginating, all other parameters provided to `ListAndroidDeliveryDataRequest` must match the call that provided the page token.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

              "delayedMessageThrottled": 3.14, # The percentage of accepted messages that were delayed due to message throttling, such as [collapsible message throttling](https://firebase.google.com/docs/cloud-messaging/concept-options#collapsible_throttling) or [maximum message rate throttling](https://firebase.google.com/docs/cloud-messaging/concept-options#device_throttling).

FCM will drop messages if the target device is deemed inactive by our servers. If a device does reconnect, we call [OnDeletedMessages()](https://firebase.google.com/docs/cloud-messaging/android/receive#override-ondeletedmessages) in our SDK instead of delivering the messages.

Specifically, each app instance can only have 100 pending messages stored on our servers for a device which is disconnected. When that device reconnects, those messages are delivered. When there are more than the maximum pending messages, we call [OnDeletedMessages()](https://firebase.google.com/docs/cloud-messaging/android/receive#override-ondeletedmessages) in our SDK instead of delivering the messages.
              "pending": 3.14, # The percentage of messages accepted on this day that were not dropped and not delivered, due to the device being disconnected (as of the end of the America/Los_Angeles day when the message was sent to FCM). A portion of these messages will be delivered the next day when the device connects but others may be destined to devices that ultimately never reconnect.

The date is relative to the Gregorian Calendar. This can represent one of the following: * A full date, with non-zero year, month, and day values. * A month and day, with a zero year (for example, an anniversary). * A year on its own, with a zero month and a zero day. * A year and month, with a zero day (for example, a credit card expiration date).

`list_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

            Returns:
              A request object that you can call 'execute()' on to request the next
              page. Returns None if there are no more items in the collection.
