Google is releasing the first Developer Preview of Android 14, and your feedback in these previews is a critical part of making Android better for everyone. Android 14 continues to improve our productivity as developers, along with enhancements to performance, privacy, security, and user customization. This preview is just the beginning, and we’ll have lots more to share as we move through the release cycle.
The?Android 14 developer site?has lots more information about the preview, including downloads for Pixel and the release timeline.
Android 14 builds on the work done in Android 12L and 13 to support tablets and foldable form factors. To help us build apps that adapt to different screen sizes, Google created?window size classes,?sliding pane layout,?Activity embedding, and?box with constraints?and more, all supported in Jetpack Compose.?
Android 14 continues to optimize the way apps work together, improve system health and battery life, and polish the end-user experience.

Multi-device experiences?are a big part of the future of Android. You can get started today with the?Cross device SDK?preview, allowing you to build rich experiences that intuitively work across different devices and form factors, and there's more to come.
In Android 14, Google is making changes to existing Android APIs (Foreground Services?and?JobScheduler) including adding new functionality for?user-initiated data transfers, along with an updated requirement to declare?foreground service types. The?user-initiated data transfer?job will make managing user initiated downloads and uploads easier, particularly when they require constraints such as downloading on Wi-Fi only. The requirement to declare?foreground service types?allows you to clearly define the intent of the background work of your app while making it clear which use-cases are appropriate for foreground services. In addition, Google Play will be rolling out new policies to ensure the appropriate use of these APIs, with more details coming soon.
The Developer Preview has everything you need to try the Android 14 features, test your apps, and give feedback. For testing your app with tablets and foldables, the easiest way to get started is using the Android Emulator in a tablet or foldable configuration in the latest preview of the Android?Studio SDK Manager. For phones, you can get started today by?flashing a system image?onto a?Pixel 7 Pro, Pixel 7, Pixel 6a, Pixel 6 Pro, Pixel 6, Pixel 5a 5G, Pixel 5, or Pixel 4a (5G)?device. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio.
