This document provides an introduction and overview of Android Things and developing connected devices using Android Things on a Raspberry Pi 3. It discusses the Android Things framework and support library, compatible devices, key differences from regular Android like optional displays and restricted permissions, and demos connecting a button to a Raspberry Pi 3 running Android Things. Helpful links are also provided to setup guides and sample code.
Android things intro
- 1. Introduction with Raspberry Pi 3 +RobertoOrgiu @_tiwiz +MatteoBonifazi @mbonifazi +DanieleBonaldo @danybony_
- 2. If you can build an app, you can build a device.
- 3. Android Things Build connected devices for a wide variety of consumer, retail, and industrial applications. ● Build connected devices using familiar tools, such as Android SDK and Android Studio ● Google Play Services & Google Cloud ● Flashable image + SDK (Developer Preview) Android Things
- 5. Things support library ● Peripheral I/O ○ API GPIO, PWM, I2C, SPI, UART ● User Driver API ○ Inject hardware events into the framework Things Support Library
- 6. Behaviour changes ● Missing core packages (ContactsContract, MediaStore, Settings etc.) ● Displays are optional ● Subset of Google Play Services available ● No runtime permissions ● No notifications Behavior Changes
- 8. SUPPORTED!!!!! Firebase * Nearby FIT Location Instance ID Cast Mobile Vision Drive Places
- 9. Displays are optional Android Things does not require a display ● Supports graphical user interfaces using the same UI toolkit ● Does not include the system status bar or navigation buttons. ● Even without display, activities are still a primary component of your app
- 10. Key Points ● Permissions are not supported since UI is not required. ● Declare permission in the AndroidManifest.xml ● Notifications are no supported since SystemBar is not required
- 11. Developer Preview 2 Date: February 2017 Build Number: NIG40 ● USB Audio support ● Bluetooth is currently disable ● Access to peripheral I/O from C/C++ code ● USB APIs are currently disabled.

- 15. Raspberry Pi 3 Model B
- 16. Setup Overview ● Use usual tools to flash the MicroSD ● Connect to the router via Ethernet ● Connect via WiFi with procedure or sample app ● Connect to adb over WiFi ● Profit
