Tapatalk is an app many Android owners are using to view forums, just like PPCG, straight from their devices. It's not an official tapatalk app, but it supports all 8,000 tapatalk enabled forums. Free version lets you view content, while the $2.99 pro version will let you reply to posts, open threads, subscribe, search, and all that good stuff. It'll be out very soon.
