you should check if the directory exist!

File directory = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES), MEDIA_NAME);
if(!directory.exist()){
    directory.mkdirs();
}

Answer 2

/**
 * ReName any file
 * @param oldName
 * @param newName
 */
public static void renameFile(String oldName,String newName){
    File dir = Environment.getExternalStorageDirectory();
    if(dir.exists()){
        File from = new File(dir,oldName);
        File to = new File(dir,newName);
         if(from.exists())
            from.renameTo(to);
    }
}

Answer 3

The problem is in this line,

File from = new File(directory, "currentFileName");

Here currentFileName is actually a String you dont have to use "

try it this way,

File from      = new File(directory, currentFileName  );
                                    ^               ^         //You dont need quotes
