从Android Studio中的Gradle项目提交到VCS的内容

I am using Android Studio 0.4.6 and Gradle 1.10. I want to commit into git the necessary files and folders, so that anyone cloning the repository can start working with the project and will not have any issues of missing files/settings because of not commited file. Could someone point what is needed to be into VCS and what is optional.I am using Android Studio 0.4.6 and Gradle 1.10
