Seconded and thirded. The linked article makes a few mistakes that would be avoided if the author paid some attention to the Android guide. Which is extremely common for third party tutorials. The Android guide is great and is often updated. There's ton great resources like videos and tutorials. It's by a huge margin the best place to learn android. I would advise anyone beginning Android development to avoid third party tutorials as much as you can. Only use those if you cannot find a specific topic you need in the Android guide.
