Solution 1:

You could iterate trough the files in the folder(s) your application is targeting and get the newest file trough the lastModified() method then you could get it's location with the getPath() method.

public File getNewestFileInDirectory() {
   File newestFile = null;

   // start loop trough files in directory
   File file = new File(filePath);
   if (newestFile == null || file.lastModified().after(newestFile.lastModified())) {
      newestFile = file;
   }
   // end loop trough files in directory

   return newestFile;
}
