It's the exact same idea. Just for android. Hopefully pioneer will support this in the nex as well. I personally am an iOS fanatic but everyone should be able to use their phones as they please without being locked in.

it should be an app in android phones, that can be launch like appradio app...

The connection system has not been discussed but something tells me it is a proprietary system like carplay and more complex than simply an app on the phone, since google states you can't use the phone while in this mode.
