So when I create my project using Android ADT (v22.3.0-887826) I target android 4.3 and have everything set to default. The src folder is completely empty. From my understanding from the lynda tutorial I am following, it should generate a general MainActivity.java. I triple checked and made sure when I was creating the project, that Create Activity was checked.
I have also tried to create a new Activity (New -> Other -> Android -> Android Activity) and it generates nothing.
