4 likes3,361 views
The document discusses 'Android Things', Google's IoT operating system, which addresses challenges such as interoperability, security, and scalability. It highlights the platform's architecture, features, and developer tools, emphasizing its integration with existing Android development practices while providing extended APIs for IoT applications. Moreover, it outlines the support for certified hardware and the management of the board support packages by Google.
Android Things : Building Embedded Devices
- 1. Android Things: Building Embedded Devices – An Introduction Mubeen Jukaku Emertxe 4-March „17 EFY Conference
- 2. Agenda Bit of History What is Android Things Architecture Summary Q & A
- 3. A bit of History Embedded Linux Android Brillo
- 4. Embedded Linux A set of ad-hoc methods to package the Linux kernel with a (minimal) filesystem. FS content “to be determined” case-by-case APIs are specific to each device/build “Core software”: • BusyBox • U-Boot • GNU Toolchain Your flavor of: • glibc or uClibc or eglibc • yocto or buildroot or eldk or ltib or ptxdist or ... No serious UX framework
- 6. Android ... apart from its ubiquitous UX ... Fully-integrated IDE: Android Studio SDK/NDK ADB Fastboot Published, well-known, and very rich APIs A large and growing developer community And still we can use “embedded Linux” components: • GNU toolchain, BusyBox, u-boot, … An actual standardized dev. env. across all product lines
- 9. Project Brillo Initial Google platform for IoT Based on Android Announced at Google I/O 2015 Never officially released Remained in “developer preview” mode Needed to sign up for developer preview on https://developers.google.com/brillo/ Sources available from android.googlesource.com “Apps” talk straight to HALs
- 11. Android Things - Overview
- 12. Why Android Things? IOT challenges Complex technologies Interoperability Security Scalability
- 13. What is Android Things
- 14. What is Android Things… “Reboot” of Google's Android IoT strategy Reinstates full Android environment Developers use existing Android dev tools C/C++ available through NDK Extended APIs for IoT Currently at Developer Preview 2
- 15. Features Status Features Status Memory Footprint < 500 MB Public Availability Developers Preview 1- Dec ’16 Developers Preview 2 - Feb ’17 Android SDK, Runtime, APIs Developers Preview 1 TensorFlow (ML library) Supported Device Usage Metrics Future Release Security Future Release OTA Updates Future Release Weave Future Release
- 16. What is Android Things…
- 17. Turnkey Hardware Solutions Device production for all Certified Integrated Hardware Google BSPs SoMs integrate the SoC, RAM, Flash Storage, WiFi, Bluetooth and other components onto a single board •The Board Support Package (BSP) is managed by Google. •SoM vendors may provide the BSPs. •OEMs provide HAL for sensors and actuators as APKs. Comes with FCC certifications Trusted platform to develop on with standard updates and fixes from Google. You can optimize your board design by flattening existing modules onto a PCB to save costs and space.
- 19. Weave Open Communication Platform Devices can connect and interact with one another, the internet, and your phone Ensures that access to your device and user data is secure and private. Transports: 802.15.4 (zigbee, threads), BLE, WiFi, Ethernet, Others possible
- 20. Trust & Security Long Term Support
- 21. Security… Security Requirements from Google* are largely the same as Android: SE-Linux Enforcement Android Verified Boot, Cryptographic Chain of trust Google Android Trusty HW Keymaster 2.0 No Gatekeeper
- 24. Android Things Architecture Java API framework Google Services API Level 7.0 ( Nougat ) Graphics optional Things Support Library OTAs received directly from Google
- 25. Behavior Changes Standard system apps and content providers absent Missing core packages (ContactsContract, MediaStore, Settings etc.) Subset of Google Play Services available No runtime permissions (Install time) No notifications, no system-wide status bar
- 26. Behavior Changes… Displays are optional Supports graphical user toolkit Does not include the system status bar or navigation buttons. Even without display, activities are still a primary component of your app
- 27. Behavior Changes… Home activity support Home launcher replaced by IOT_LAUNCHER Android Things expects one application to expose a "home activity“ in manifest file System launches application on boot
- 28. Things support Library Peripheral IO APIs (PIO) • Enables Apps to talk to sensors and actuators • Supports GPIO, I2C, UART, PWM, SPI User driver API • Extend existing Android framework services • Allow apps to inject hardware events into framework that other apps can use.
- 31. Summary Android Things is Google‟s IoT OS Certified (but limited) Hardware SoM support (current) Developers use existing Android dev tools Addresses most of the IoT challenges Extended APIs for IoT (Things API)
