Not gonna happen. What'sapp is CLOSED SOURCE software. It is not a problem with airdroid not supporting What'sapp. It is a problem of what'sapp not allowing it.
Shame so many people are still choosing the use closed, instead of OPEN SOURCE software. These kind of problems wouldn't exist with a truly open messaging system.

A few problems:
no official APIincompatible, closed source XMPP
(which they can change after someone uses the reverse engineered protocol)not allowed by WhatsApp PolicyCrypted SQLite DB
(there is a WhatsApp DB Decryptor in Pyton, but again: WhatsApp can change its encryption easily)So, forget it!
