Using Adobe Acrobat embedded in an Mobile App

We're looking at utilizing all the features of Acrobat Reader Mobile into a custom developed app for iOS and Android. We've searched to find any SDK for each of the platforms with no avail, I recall Adobe offered such a solution, and developing a custom module that read and re-implement the same features is not ideal. Our solution is for an enterprise custom mobile app development, and was curious if anyone stubmled on such a request. Client is looking pay for a solution, however, does Adobe offer such an SDK?

We've been developing mobile apps for 10 years, and have seen many modules that mimic Acrobat reader, however shouldn't adobe offer an official library that is supported for all current future features that may be integrated in Acrobat?
