Create Android Magazine Kiosk App

I'm looking to create a basic magazine reader. The magazines will be delivered in PDF format and multiple issues should be available for download and reading in app. One app will need to let the user select from multiple magazines. All data will be returned from a server in JSON format. I'll update the app later to pull from my server, for this app I just need to be able to pull magazines from a demo server with sample PDFs. Source code will obviously need to be released with the app, so that I can update it myself in the future. If you need an example of features that I'm looking for, take a look at Librelio. They are a subscription/open source solution for digital magazines, and they provide a great set of features. Ideally you'll have created similar apps previously. Please provide samples of past magazine apps you've published to the Play Store.
