1. Getting started with Android Things
2. Google’s new OS for IoT devices
3. Internet of Things — network of devices that collect and exchange data
4. • Lightning • Locks • Security cameras • Voice assistants • Self-driving cars • Thermostats • “Smart-everything” IoT applications
5. IoT at Google: recent history
6. Brillo and Weave introduced at I/O 2015
7. Weave — communication language between device and cloud
8. Brillo — simplified version of Android for IoT devices
11. Android Things is the new Brillo
12. Android Things is the new Brillo ¯\_(ツ)_/¯
13. Android Things • Available for everyone for free • Android Studio and Android SDK • Firebase and Google Play Services • Regular updates from Google • Community • The ease and power of Android
14. If you can build an app, you can build a device - Google
15. Project idea “Smart house” solution for simple electronic devices
16. Raspberry Pi 3 Model B • A 1.2GHz 64-bit quad-core ARMv8 CPU • 802.11n Wireless LAN • Bluetooth 4.1 • 1GB RAM • 4 USB ports • 40 GPIO pins • Full HDMI port • Ethernet port • Costs ~$50
17. Before Andorid Things...
18. ... there were no Android, which meant running on a traditional Linux or Windows based OS PROS • You are in control of everything CONS • With great power comes great responsibility • You do all the hard work • You reinvent a wheel
19. Android Things to the rescue!
20. SmartHouse project Two apps For mobile and Android Things devices
21. SmartHouse mobile • You have list of devices • You can turn them on or off • You can add new device • Many users can add to the same device and control it • You see when other users toggle your devices
22. SmartHouse for Android Things • Initialize hardware • Read events via Firebase Realtime DB • Change the state of hardware • Listen to device state change and post events (not implemented yet)
23. How to create Android Things project? 1. Open Android Studio 2. Create New Project for phones/tablets 3. Setup Android Things dependencies 4. Done
24. Hardware side gpio = manager.openGpio(“BCM26”) gpio.setDirection(Gpio.DIRECTION_OUT_INITIALLY_HIGH) gpio.setActiveType(Gpio.ACTIVE_LOW) GPIO initialization Change GPIO value gpio.value = newValue
25. Firebase DB design
27. Android Things: bad things • Setup is very inconvenient • Developer preview has lots of bugs and some features are not available • No sign in support
28. Demo
