Hi Gabriel,
welcome to the forum and thank you for testing the apps.
I sent you the link to download the image for the pi in a private mail.
Please be aware that the version for the Android Things is only a developer preview, and some things are not working very well. We are having problems with the google login, and some users are unable to get the connected sensor/relay to work.
I hope we will solve those problems in the next versins.
Do you need instructions to install the image on the Pi?
best regards
R. Campos.
