Autodesk had released Design Review Mobile app for the android market.  Read more on the blog Between the Lines with Shawn Hurley.  Similar to the app for the iPad it can only use files stored on your Autodesk Cloud account making it really only work if you are on subscription.  So if you want to be able to use your own documents then you will have to get your cloud account up and running first.  I have to say I have found the iPad version really nice to use out in the field to view all sheets and even the 3D model while on site, even with the size limitation because of the iPad.  I will look forward to testing this out on an Android device to see how the size limitation is going to be affected.
