A lot of IOT development is using android as a base OS, yes.

Mobile device? Not necessarily, but lots of IoT with WiFi or Ethernet only interfaces
do use android as a base OS.

I think he's arguing that android should do IA_NA/IA_TA not only because of the
situations that desire it for general purpose mobile devices, but also because
it's even more important for IOT things that are being built on the android platform.

I could be wrong, Clark can certainly correct me if I misunderstood his concern.

Owen

I can speak for Clark, but IOT and other things that are not general purpose mobile devices are what I'm thinking about.

<bhs> When I look at the Nook eReader that uses the Android OS, I notice that it just references a bunch of Open Source Apache 2.0 licenses for the Android OS components they use. To me, this says IoT devices are in no way beholden to a Google app store or Google restrictions around what goes into an Android smartphone. I see on https://source.android.com/devices/architecture/modular-system/networking that it says Android 10 included a DhcpClient component that "obtains IP addresses from DHCP servers so they can be assigned to interfaces". So it sounds like IoT devices that use Android already have the ability (if the manufacturer wants) to support IA_NA?
