How to create a JavaDoc for an Android library project that includes the existing jar documentation that the library project uses

I am developing an android library that will be distributed as ".jar". My library project includes an already available jar in it. so now I would like to create a documentation for my library that can link to the existing jar documents that my project includes.

eg. My library class is A, which implements interface B (inteface jar that my project is using), now in my documentation when someone clicks on B, then I have to include the documentation of that library as well.

I have a quick release. rply asap guys.
