Sources: Google preparing ‘ADT-4’ developer box for Android TV with upgraded specs - 9to5Google

After its two-year-old streaming dongle for Android TV developers goes by the wayside, we’ve confirmed that Google is preparing an ADT-4 streaming box for Android TV development which brings a number of upgrades.

Google has designated three devices so far as Android TV’s developer device, eligible for new builds of the platform and designed with app testing in mind.

We now have evidence that Google is preparing an ADT-4 device for Android TV development which has upgraded specs and a box form factor rather than another dongle.

This device appears to be based on a developer box currently sold by DroidLogic.tv.

If so, that would point to ADT-4 including 2GB of RAM, 16GB of storage, and more input/output than any other Android TV developer device.

These ports make the device far better suited to Android TV’s current state.

TV tuner hardware better allows for developers to test their apps for TVs with Android TV OS built-in, while more and more Android TV devices have been integrating native support for far-field microphones and an always-listening Google Assistant.

We found a direct connection between “ADT4” and the Amlogic model number AH212, which is a device that has been worked on in Android code since early 2021 and is also being used as a developer device for YouTube.

Notably, one of these code changes was found with Android TV 14, which appears to be in development for ADT-4.
