Here is my .gitignore file, to get the necessary parts of a fresh project into the repository and leave some of the rest out for the Android Studio I/O Preview.

*.iml
*.iws
*.ipr
.idea/
.gradle/
local.properties

*/build/

*~
*.swp

To get the data out of the repository, one has to import it using the cradle files. To run it one has to create a new Android Application entry through the Run/Edit Configurations menu.
