Introduction introduction

You can use the Roku SceneGraph XML programming framework to develop applications. This framework features two key concepts:

  • SceneGraph rendering of the application screens
  • XML configuration of the SceneGraph screens

The Adobe Mobile SDK for Roku is written in BrightScript. The SDK uses many components that are not available for an app running on SceneGraph (for example, threads). Therefore, a Roku app developer intending to use the SceneGraph framework cannot call Adobe Mobile SDK APIs (the latter are similar to those available in legacy BrightScript apps).

Architecture architecture

To add SceneGraph support to the AdobeMobile SDK, Adobe has added a new API that creates a connector bridge between the AdobeMobile SDK and adbmobileTask. The latter is a SceneGraph node used for the SDK’s API execution. (Usage of adbmobileTask is explained in detail throughout the rest of this document.)

The connector bridge is designed to perform as follows:

  • The bridge returns a SceneGraph-compatible instance of the AdobeMobile SDK. The SceneGraph-compatible SDK has all of the APIs that the legacy SDK exposes.
  • You use the AdobeMobile SDK APIs in SceneGraph in a very similar way to how you used the legacy APIs.
  • The bridge also exposes a mechanism to listen for callbacks for APIs that return some data.

Components components

SceneGraph Application:

  • Consumes AdobeMobileLibrary APIs via the SceneGraph connector bridge APIs.
  • Registers for response callbacks on adbmobileTask for expected output data variables.

AdobeMobileLibrary:

  • Exposes a set of public APIs (Legacy), including the connector bridge API.
  • Returns a SceneGraph connector instance that wraps all legacy public APIs.
  • Communicates with an adbmobileTask SceneGraph node for execution of APIs.

adbmobileTask Node:

  • A SceneGraph task node that executes AdobeMobileLibrary APIs on a background thread.
  • Serves as a delegate to return data back to application scenes.

adbmobileTask Node

Field
Type
Default
Usage
adbmobileApiCall
assocarray
Invalid
Do NOT modify this field or let is be used by the Application. This field is used by the ADBMobile SceneGraphConnector to route API calls via SceneGraph nodes and to fetch responses. Therefore, this key/field is reserved for AdobeMobileSDK for SceneGraph compatibility. Important: Any modifications to this field may result in AdobeMobileSDK functioning incorrectly.
adbmobileApiResponse
assocarray
Invalid

Read-Only All of the APIs executed on AdobeMobileSDK will return responses on this field. Register for a callback to listen for updates to this field in order to receive response objects. Following is the format for the response object:

response = {
  "apiName" : <SceneGraphConstants.
               API_NAME>
  "returnValue : <API_RESPONSE>
}

An instance of this response object will be sent for any API call on AdobeMobileSDK that is expected to return a value as per the API reference guide. For example, an API call for visitorMarketingCloudID() will return the following response object:

response = {
  "apiName" : m.
              adbmobileConstants.
              VISITOR_MARKETING_CLOUD_ID
  "returnValue : "07050x25671x33760x72644x14"
}

OR, response data can be invalid as well:

response = {
  "apiName" : m.
              adbmobileConstants.
              VISITOR_MARKETING_CLOUD_ID
  "returnValue : invalid
}
