I am trying to make an Android Xamarin Binding Library (for Zendesk). The initial problem is that this library is a multiple AAR project. The standard problem is that the binding library can only bind to one AAR at a time. If there are multiple AARs, then the binding will only occur for one of them (the newest one added from my experience). (Bugzilla, Xamarin.Forums on AAR, many others can be found).
Keep in mind, with everything I say below, there are a lot of Jar files that needs to be added in as EmbeddedReferenceJars.
I first tried to put all of the files into a single folder (and name them from the folder they came from), and combine any resources into a single folder.
I zipped that up, renamed the zip folder into an AAR and tried to bind the project. After doing some things in metadata.xml and what not, I successfully compile the binding project with warnings, but the test app runs into the problem stated below.
From there, I decided to try to see what would happen if I put each AAR into this folder unzipped, and see the result (I had to put the classes.jar at the main level to try to bind). 
I zipped that up, renamed it into an AAR and tried to bind the project. After some minor edits, I successfully compile the binding project with warnings, but the test app runs into the problem stated below.
The next thing I tried is To make an Binding Project for each AAR, and in each binding project, put the other AAR's classes.jar file as an EmbeddedReferenceJar so that it could build. Again: I run into the problem stated below.
The problem that I keep running into is that the R file from the binding is not being compiled, and will not allow for the test app to compile. (i.e. can't find string @string/contact_fragment_title, which I can confirm is both in the values.xml and R.txt file). I have tried to put the strings into my personal Strings file on the test project, or just removing the references to this strings altogether. When I do so, I can compile the test app, but I get an error stating that com.zendesk.sdk.R$attr NoClassDefFoundError.
Any help would be greatly appreciated. And if I need to clarify anything (my writing is horrible), feel free to ask.
