hi, could you give me some ideas about translating the app into spanish? i'm kinda lost, any help is welcome ! thanks
Well, you have to download translation pack from first post. Then you unzip it and open strings.xml in text editor. And you can start translationg text inside xml marks <string>, for example:
EN: <string name="cancel">Cancel</string>
ESP: <string name="cancel">Cancelar</string>
You can compare the english string with application, to have better imagination where these strings are located.
