Normally you would start here https://www.adobe.com/cfusion/mmform/index.cfm?name=distribution_form&pv=rdr but I see that the Android Reader version is not on that list.
I will move your post to the Android subforum in the hope that one of the mobile developers will be able to respond to your request.
I believe that one of your colleagues had already sent an inquiry into our Mobile Distribution email earlier in April. The request is in process now.
If you would like to inquire, you can email firstname.lastname@example.org.
