Android Armory Offline signing using QR?

[bonbon]

I have been searching for a long time but didnt find an answer for this,

Does Armory have a feature on android as follows:

Have private keys on offline android mobile,

scan a transaction using QR,

Sign it Offline,

Send back to online system using animated QR



They added the feature for sending raw and signed transactions, is it available for android.

Why dont we see this being widely used for secure storage.

Thanks!
