Today, we're releasing Developer Preview 5 (DP5) of Android Things, which includes the major change of being based on the upcoming Android O release. Android Things is Google's platform to enable Android Developers to create Internet of Things (IoT) devices, and seamlessly scale from prototype to production.
Android O
Android O is currently under Developer Preview for phones and tablets, and DP5 is now based on this upcoming release (previous releases were based on Android N). This means that your future Android Things applications should target API 26 to work correctly on the platform with our support libraries.
Hardware Changes
DP5 now adds support for the new NXP SprIoT i.MX6UL design, as listed in our developer kits documentation. With Intel discontinuing the Edison and Joule hardware designs, these platforms are moving to legacy support. They will not continue to receive the latest platform updates, but developers may continue to access the DP4.1 system images from the Android Things Console.
An important goal of Android Things is to help developers seamlessly scale from prototype to production. When we exit Developer Preview, we will differentiate between hardware platforms targeted for prototyping-only and hardware reference designs that can scale to production. Production-ready hardware will satisfy Google's security requirements and include long term support from the silicon manufacturers. We will have more to share later on.
Improvements
With the move to the Android O codebase, there are new API features from Android as well as specific features for Android Things. For those developers using UserDriver APIs, you will need to add new permissions to your AndroidManifest.xml. The documentation contains details about the permissions needed for each driver type. DP5 also now supports OpenGL ES 2.0 and WebView on the Raspberry Pi 3, which was a highly requested feature from developers. We have also implemented dynamic pin muxing for the Raspberry Pi 3, with pins being configured at runtime depending on what features are being used.
Android Studio
The samples for Android Things are now available directly in Android Studio for browsing and importing. You can now go to File, New, Import Samples, and search for Things to see everything that is available. We have a wide range of samples, demonstrating how to interact with buttons, sensors, LEDs, and displays, as well as implementing Google Assistant and TensorFlow.
Android Things Console
We recently launched the Android Things Console, which provides the ability to support over-the-air updates (OTA) to Android Things devices. We have recently made a number of UX improvements to the console to improve usability and functionality. DP5 is now available within the Android Things Console, but the DP5 update will not be pushed automatically to devices without your intervention. You will need to update your application for DP5, then create a new update and push it via the console yourself.
Feedback
With Android Things being updated to Android O, significant changes have been made to the platform. Please send us your feedback by filing bug reports and feature requests, and asking any questions on Stack Overflow. To start using DP5, use the Android Things Console to download system images and update existing devices. More information about the changes are available in the release notes. You can also join Google's IoT Developers Community on Google+, a great resource to get updates and discuss ideas. Also, we have our new hackster.io community, where everyone can share the amazing projects they have built!
