Hi,
While there is no specific OTK SDK, there are both Android and iOS Mobile SDKs that let you create apps that leverage the OAuth features of the OTK. To use these SDKs you need CA API Gateway 9.1, OTK 3.5, and the Mobile API Gateway 3.2. Optionally, you can also install CA Mobile App Services (MAS) 1.2.
The SDKs are documented on the developer site: mas.ca.com
Access the latest SDKs here:
iOS-MAS-Foundation
Android SDK
The MAS wiki page contains information on how to install Mobile App Services 1.2 to integrate with the Android and iOS Mobile SDKs.
