    File dir = Environment.getExternalStorageDirectory();
if(dir.exist()){
    File from = new File(dir,"from.mp4");
    File to = new File(dir,"to.mp4");
     if(from.exist())
        from.renameTo(to);
}

File rootDir = Environment.getExternalStorageDirectory();     
File file = new File(rootDir + "/Files/"+fileName);

File file2 = new File("newname");

// Rename file (or directory)
boolean success = file.renameTo(file2);
if (!success) {
System.out.println("File was not successfully renamed");
}

This worked for me. please check once!!

I think getAbsolutePath() returns the full path including file name, that might be a problem here. Try getParent() instead and see if it works.
