自 2025 年 3 月 27 日起，我們建議您使用 android-latest-release 而非 aosp-main 建構及貢獻 AOSP。詳情請參閱「Android 開放原始碼計畫變更」。
Android 相容性定義說明文件
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
歡迎參閱 Android 相容性定義說明文件 (CDD)。本文件將列舉裝置必須符合的條件，才能與最新版 Android 相容。如要與 Android 相容，裝置實作方式必須符合本相容性定義中列出的規定，包括透過參照納入的任何文件。每個 Android 平台版本都會提供詳細的 CDD。CDD 代表 Android 相容性的「政策」層面。
請務必明確編寫 Android 相容性計畫的政策，因為沒有任何測試套件 (包括 Android Compatibility Test Suite (CTS)) 可以真正涵蓋所有情況。舉例來說，CTS 包含一項測試，可檢查 OpenGL 圖形 API 是否存在及正確運作，但沒有任何軟體測試可以驗證圖形是否確實正確顯示在螢幕上。更普遍來說，您無法測試鍵盤、顯示密度、Wi-Fi 和藍牙等硬體功能是否存在。
CDD 的角色是將具體要求明確化並加以規範，消除模糊空間。CDD 並未提供完整資訊。由於 Android 是單一開放原始碼叢書，因此程式碼本身就是平台及其 API 的完整「規格」。CDD 會做為「中心」參照其他內容 (例如 SDK API 說明文件)，提供可用於 Android 原始碼的架構，讓最終結果成為相容的系統。
如果您想建構與特定 Android 版本相容的裝置，請先檢查該版本的原始碼，然後閱讀對應的 CDD，並遵守相關規範。
您可以將最新的 CDD 做為 HTML 網頁格式查看。

This document\nenumerates the requirements that must be met in order for devices to be\ncompatible with the latest version of Android. To be considered compatible with\nAndroid, device implementations MUST meet the requirements\npresented in this Compatibility Definition, including any documents\nincorporated via reference. For each release of the Android platform, a\ndetailed CDD will be provided. The CDD represents the \"policy\" aspect of\nAndroid compatibility.\n\nIt is important the policy of the Android compatibility program is codified\nexplicitly as no test suite, including the\n[Android Compatibility Test Suite (CTS)](/docs/compatibility/cts),\ncan truly be comprehensive. For instance, the CTS includes a test that checks for the presence and\ncorrect behavior of OpenGL graphics APIs, but no software test can verify that the\ngraphics actually appear correctly on the screen. More generally, it's\nimpossible to test the presence of hardware features such as keyboards, display\ndensity, Wi-Fi, and Bluetooth.\n\nThe CDD's role is to codify and clarify specific requirements, and\neliminate ambiguity. The CDD does not attempt to be comprehensive. Since\nAndroid is a single corpus of open-source code, the code itself is the\ncomprehensive \"specification\" of the platform and its APIs. The CDD acts as a\n\"hub\" referencing other content (such as SDK API documentation) that provides\na framework in which the Android source code may be used so that the end\nresult is a compatible system.\n\nIf you want to build a device compatible with a given Android version,\nstart by checking out the source code for that version, and then read the\ncorresponding CDD and stay within its guidelines.\n\n\nYou may view the latest CDD as an [HTML](/docs/compatibility/android-cdd) web page.\n\nFind released versions of the CDD and approved release version strings here:\n\n| Version | PDF
