I'm gonna go ahead and plug the app StrimBagZ for Android. It has BTTV and FrankerFaceZ integrated into it (same exact ZreknarF button on the right side of the chat window), lets you copy text in the chat, and lets you follow links in-app without disconnecting from the chat. It has chatroom support too, but there's still some bugs with it. Overall, it's my favorite Twitch app by far.
