Android Things, The IoT Platform for Everyone

Ever wanted to try Android Things? Have you been intrigued by using Android for IOT? Visit this workshop! We will have Android Things Devkits including some cameras, buttons, LEDs, fans and more.

We will build a collective display and display a message together using buttons.

Never worked with hardware before? Don’t worry, we will help you to get up and running in a few minutes.

We will also talk about connecting Firebase to your Android Things application.

You will need your own laptop for this workshop. Please have an up to date Android Studio installed, update your SDK to at least API-Level 26 (AndroidOreo) and have a look at https://developer.android.com/things/preview/index.html Hardware setup will happen during the workshop.
