This project is an experiment based on Android Things and Google Photos API that will let you create a photo boot (like those usually found at weddings) that will automatically upload the taken pictures to Google Photos albums.
Our system was based on a Raspberry PI equipped with a Rainbow HAT, an external 21,5" monitor (without touchscreen), a big red Normally Closed (NC) button to snap the pictures and an external camera module.
Since Google Photos requires an authentication, we provided a companion Android app that will let you log into an account and will share the token with Android Things using Nearby API.
We did not equip our board with a 4G module, so we set up a mobile hotspot and that was enough to upload the pictures to the album.
The project is written in Kotlin and it's based on Android Things. For the networking layer, we used Retrofit and OkHttp.
