It's not at all clear what you're asking here. What do you need to do? How does it need to be encrypted? – Wouter Verhelst Feb 16 '16 at 07:37

Use CipherOutputStream and CipherInputStream for encryption and decryption of file in android.
There are two ways through which you can achieve your goal
Download a file and encrypt it, when you want to play that file decry-pt it in a temporary file and play it.
if you want to play encrypted file on the fly (not decrypting it in a temp file) then you can use Libmedia library. It streams encrypted file on local host and play it from there
