I have recently updated Android Studio to version 0.2.1, only to find myself in a difficult sitation yet again. This time the compiler says: "Abnormal build process termination: Error: Could not find or load main class Files"!
This is what my screen looks like: https://lh3.googleusercontent.com/-srUlUCSl2iI/Ue0BqrXJgCI/AAAAAAAAARw/4UZ0IExLWRk/w958-h766-no/Untitled.jpg
I had the same issue. My solution was to right click main and and mark it as source root
