多工處理和多實體
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
第 1 級 — 大螢幕差異化
大螢幕裝置的寬廣螢幕空間可讓使用者同時執行多個應用程式或同一個應用程式的多個執行個體，進而提升使用者體驗並提高工作效率。
多工處理
應用程式可在分割畫面模式中並排執行，或在桌面視窗模式中以可移動且可調整大小的獨立視窗執行。應用程式可透過深層連結在另一個視窗中開啟其他應用程式、在自己的視窗中開啟附件，或以子母畫面模式播放影片。
多執行個體
應用程式可以在個別視窗中啟動多個本身的實體，用於文件編輯、網路瀏覽、檔案管理和產品比較。

Your app can open another application in\na separate window from a deep link, open attachments in their own windows, or\nplay videos in picture‑in‑picture mode.\n\nMulti-instance\n--------------\n\nYour app can launch multiple instances of itself in separate windows for\ndocument editing, web browsing, file management, and product comparisons.\n\nNext steps\n----------\n\nTo learn how to make the most of multitasking and multi‑instance use\ncases, see the following developer guides:\n\n- [Support multi-window mode: Compose](/develop/ui/compose/layouts/adaptive/support-multi-window-mode)\n- [Support multi-window mode: views](/develop/ui/views/layout/support-multi-window-mode)\n- [Support desktop windowing](/develop/ui/compose/layouts/adaptive/support-desktop-windowing)\n- [Add videos using picture-in-picture (PiP)](/develop/ui/views/picture-in-picture)"]]
