问题 Why different boards have different GPIO names in Android Things? For example, in Raspberry PI 3, there are BCM6 , while Intel Edison with the Arduino breakout has IO12 , IO13 , etc. 回答1: GPIO (and other peripheral port handle) are named after the SOC/SOM documentation for each supported board. Boards like the Edison Arduino breakout or the Sparkfun Edison Pi block have the same pin name directly on their silk screen. When this information is missing, you can consult the pinout reference in

问题 I'm developing an app on Raspberry Pi 3 using Android Things as OS. I started using the normal Raspberry Pi 3 with the official touch screen. Everything worked fine, so I tried the same setup on the development board with the rpi compute module 3 lite (CM3L). Unfortunately the display doesn't turn on. After some research I found this: https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-display.md Seems like I have to adjust the options for SDA and SLC on the OS as well as

Display via HDMI is good on 0.4.1-devpreview 回答1: Try to check Balaji BABU T.R.'s solution from comments to Wayne Piekarski announce on Google's IoT Developers Community: Open config.txt in Notepad ++ paste below things # uncomment this if your display

问题 I am building this app on android things. I want to be able to give it access to media files on a USB stick or maybe even the raspberry pi's SDcard. I don't know what I'll have it do with those files yet but I just wanna know if its possible. If it isn't that's fine I have other solutions but I figured I would start with the obvious approach first. 回答1: I'm didn't try it, but seems it's possible by the same way as in normal Android OS. To do this You should mount Your USB dongle into the
