How to merge two reader applications into one
<p>I have two android applications with source code.  One is a PDF reader and another is an ePUB reader, but I want to merge them into one app so that it will act as a single application and when I will download the epub it should open with epub reader and similarly when I will download the pdf it should open with pdf reader.</p>

<p>Can anyone offer any tips on how to proceed?</p>
