IMPORTANT NOTE FOR ANYONE CONSIDERING USING THIS: Don't do it! It's out of date. The Eclipse software no longer works with Android.
I think this is out of date. In the version of Android Studio I downloaded and installed today, there's no "Blank Activity" option. Also, the strings.xml file is not readily available; I had to look at another comment to see where it was. Plus the "hello world" string isn't in there.When I try to run this, I'm told that android.support.design.widget doesn't exist... which is bewildering, because it automatically added that import to my Java file! Why would it do that if it doesn't exist? Apparently the solution is to edit the Gradle file, but I don't know what that is and don't feel like figuring it out now. I'm not sure if this is relevant to the tutorial but I thought I'd bring it up just in case.
