project folder path from a java class wihin an android project

I am making an android application which is using a java class full of static data. I want to save some of that data in an xml file within the project. I made a test xml file which is currently in my assets file, but I can't seem to find a way to access that file from within the java class. is there a way to get to reaccess that folder path using code so I can read and write in the xml file?
