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 TV 模擬器，試用部分新的使用者介面功能，例如背景模糊和 4K UI 支援。
如何開始
如果您有現有的 ADT-3 開發人員裝置，裝置會自動透過無線更新 (OTA) 接收 Android 12。或者，您也可以按照下列步驟安裝 Android 12：
使用 ADT-3 開發人員套件開發 Android TV 應用程式。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。
警告： ADT-3 刷入 Android 12 後，如要返回先前的 Android 11 版本，必須清除使用者資料。
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，然後將映像檔更新到裝置上。
