I created a bitbucket repository containing some unix scripts and groovy scripts I use when developing android applications. I will continue adding things as I need them. I hope somebody else gains time using these.
Let me know if you use them and feel free to add things in the bitbucket repository.
Currently it contains a conversion script from svg to png's in the different sizes needed and conversion from strings.xml location files to a csv and the other way round to ease collaboration with another team doing the translation. The wiki should explain more.
