如需 Android 12 中變更項目的完整清單，請參閱 Android 12 說明文件。請注意，並非所有功能都適用於電視。
下載 ADT-3 開發人員套件的系統映像檔，即可開始使用。或者，您也可以使用 Android Emulator for TV，試用一些新的使用者介面功能，例如背景模糊處理和 4K UI 支援。
如何開始
如果您有現有的 ADT-3 開發人員裝置，該裝置會自動收到 Android 12 的 OTA 更新。或者，您也可以按照下列步驟安裝 Android 12：
- 使用 Android TV 專用的 ADT-3 開發人員套件。提供的系統映像檔僅適用於 ADT-3 開發人員裝置。
- 下載系統映像檔。
- 在 ADT-3 裝置上安裝系統映像檔。
手動安裝系統映像檔
您可以下載最新的 Android 12 系統映像檔，然後手動將該映像檔刷新至測試裝置。手動刷新裝置可讓您精確控制測試環境，並可透過指令列工具執行。
備份好裝置資料後，請下載下列任一 ADT-3 版本，然後將映像檔刷新到裝置上。
