Earlier this month, Google released a preview of the Google Assistant SDK that works on boards running Debian like the Raspberry Pi 3, and even launched AIY Project Voice Kit for the later. You can now play with Google Assistant on Android Things as the company has just released Android Things Developer Preview 4 with support for Google Assistant SDK.
The operating systems works on any Android Things certified devices, but the example instructions for Google Assistant API on Android Things also include steps to use Raspberry Pi 3 board together with AIY Projects Voice kit.
- The developer preview 4 also adds I2S to the peripheral I/O API and is demonstrated in the aforementioned example, and new hardware support with NXP i.MX7D based Pico Board equipped WiFi & Bluetooth, Ethernet, USB ports, an audio jack, and an I/O expansion port.
Android Things DP4 also brings the ability for developers to enable/disable Bluetooth profiles at run time. Finally, Google mentioned the open source hardware Edison Candle to show an example of Android Things hardware, which we shortly covered previously. Separately, Rockchip published a press release about a Rockchip RK3229 solution supporting the Google Assistant SDK and Android Things. Sadly, few details are provided in the PR, and RK3229 devkit is not listed in Android Things Hardware page.
You can download Android Things DP4 in the developer preview page.
