Surprised nobody's mentioned the Telegram Android app yet. Their ChatActivity.java is 27, 720 lines! https://raw.githubusercontent.com/DrKLO/Telegram/master/TMessagesProj/src/main/java/org/telegram/ui/ChatActivity.java https://raw.githubusercontent.com/DrKLO/Telegram/master/TMes... Thing is, there's a great knowledge of the Android OS in there and the app works great when I use it. I think the OP blog post is correct 'Users don't care about the technologies or code.'
