A single request to be sent to the Facebook Platform through either the Graph API or REST API. The Request class provides functionality relating to serializing and deserializing requests and responses, making calls in batches (with a single round-trip to the service) and making calls asynchronously.
The particular service endpoint that a request targets is determined by either a graph path (see the setGraphPath.setGraphPath(String) method) or a REST method name (see the setRestMethod.setRestMethod(String) method); a single request may not target both.
A Request can be executed either anonymously or representing an authenticated user. In the former case, no Session needs to be specified, while in the latter, a Session that is in an opened state must be provided. If requests are executed in a batch, a Facebook application ID must be associated with the batch, either by supplying a Session for at least one of the requests in the batch (the first one found in the batch will be used) or by calling the setDefaultBatchApplicationId.setDefaultBatchApplicationId(String) method.
After completion of a request, its Session, if any, will be checked to determine if its Facebook access token needs to be extended; if so, a request to extend it will be issued in the background.

newCustomAudienceThirdPartyIdRequest(Session, Context, Callback)Creates a new Request configured to retrieve an App User ID for the app's Facebook user.

The ID retrieved represents the Facebook user identified in the following way: if the specified session
(or activeSession if the specified session is null) is open, the ID will represent the user associated with
the activeSession; otherwise the ID will represent the user logged into the native Facebook app on the device.

it, or c) the app has previously called
