Android 12 for TV
Latest Update: The final release of Android 12 for TV is now available.
With the official release of Android 12, we are also making the most recent platform release available for TV.

Alternatively, the build images for the standard Android TV experience are also available for download.
We’ve added more customizations to Android 12 to improve the experience and compatibility on TV devices.

Refer to the Android 12 documentation for a full list of the changes included in Android 12. Note that not all features apply to TV.
Download the system images for the ADT-3 Developer Kit to get started. Alternatively, you can use the Android Emulator for TV, which lets you try some of the new user interface capabilities like background blurs and 4K UI support.
How to get started
If you have an existing ADT-3 developer device, the device will automatically receive an OTA to Android 12. Alternatively, you can install Android 12 by following these steps:
- Use the ADT-3 Developer Kit for Android TV. The provided system image is for ADT-3 developer devices only.
- Download the system image.
- Install the system image on your ADT-3 device.
Install system images manually
You can download the latest Android 12 system image and manually flash it to your test device. Manually flashing a device gives you precise control over the test environment and can be performed with command line tools.
After you back up your device data, download one of the following ADT-3 builds and then flash the image onto your device.

IT之家了解到,虽然这是最终版本,但它仍然是针对开发人员的,意味着普通用户无法在 Chromebox 或 Android TV 上下载它,需要一款名为 ADT-3 的设备,这是一款面向开发人员的 Android TV 适配器。
谷歌表示,现有 ADT-3 开发者设备将自动接收到 Android TV 12 的 OTA,也可以点此手动下载镜像刷入。
面向普通用户的 Android TV 12 预计会在 2022 年初上市。
