Modificated version of AlbumSample by Rodrigo

Dear Recruiter,

We use Ant instead of Maven or Gradle at current work, this made me confused about the file system in the sample project. In "AlbumSample\src\main\", I made a copy from directory "java" to directory "src". Both directories contain the codes modified.

Sorry about lack of knowledge about Gradle and Maven, and I have started to learn Gradle now.

Rodrigo.
