Hide message length in symmetric key cryptography

Is there any way to hide message length from adversary in symmetric key cryptography?

Suppose we want to hide message length from active and efficient adversaries.

Note that statistical methods can still be applied; you will have to always create a message size of $N$ if you want to full hide the length of messages of $0$ to $N$ in length - excluding normal padding that may be required for block modes of encryption. Obviously, you still leak the information that the message is lower than $N$. But that cannot be avoided; an encrypted message of size $N$ cannot be created for all messages larger than $N$.
Bit padding makes it very easy to "retrieve the location of the message inside the padded plaintext". $\hspace{.44 in}$ –  Ricky Demer May 18 '14 at 18:25
