Please use the following constants for BIP49 xpub/xprv prefixes as per http://docs.electrum.org/en/latest/seedphrase.html#list-of-reserved-numbers

Bitcoin:

0x049d7878 yprv 0x049d7cb2 ypub

Bitcoin Testnet:

0x044a5262 upub 0x044a4e28 uprv

Litecoin:

0x01b26ef6 Mtub 0x01b26792 Mtpv

This will assure that user does not accidentally imports BIP49 xpub to BIP44 watch only wallet.
