Google designed an edition of Android for the Internet of Things, called "Android Things OS", and released it in late 2016. The purpose of Android Things is to provide a platform for IoT and embedded devices. Some companies have taken interest in Android Things OS, with MediaTek announcing in May of 2017 that they would be building hardware designed specifically for Android Things, and we now have two new companies on similar paths: Qualcomm and Rockchip. The idea with these chips is to make a way for manufacturers to seamlessly create assistant smart screens and other similar utilities.
The official Qualcomm Press Release describes the two new Home Hub platforms:
Qualcomm Technologies, Inc., today announced two Qualcomm® Home Hub platforms supporting Google's Android Things. Based on the Qualcomm® SDA624 and SDA212 system on chips (SoCs), these platforms are designed to help developers and original equipment manufacturers (OEMs) to quickly and cost-effectively develop home hubs featuring Google services such as the Google Assistant
Qualcomm says that the platforms will be available to manufacturers in the first quarter of 2018, so we will likely see products utilizing them very soon. We also saw an announcement from Rockchip, a SoC for Android Things with the name "RK3229 SOM". It's also pre-certified for Google Assistant. It has not yet been announced when it will be available to OEM's, however, the specs were announced: Quad-core processor with a 1.5GHz clock speed, eMMc memory, as well as built-in Bluetooth and WIFI.
