Android Automotive 25Q2
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
Google 很高興能與 Android Automotive 合作夥伴分享這項 Android 25Q2 版本。Android 16 的 Android Automotive 25Q2 版本符合規定。我們將持續微調各項功能，目標是為 OEM 推薦即將推出的版本。
版本詳細資訊
本節將摘要說明 AAOS B 版提供的主要功能和強化項目。
這些更新適用於 Android16，API 級別 36。
Android Automotive 25Q2 版本符合 Android 16 規範。
新功能
25Q2 版本提供這些新功能。
AAOS 架構
音訊和電台：
音訊控制 HAL 改進：如要設定車輛音訊功能，請使用 API，而非 XML 檔案。
高畫質 (HD) 電台緊急警報系統 (EAS)：透過 API 將 EAS 資訊傳遞至電台應用程式。這適用於 HD Radio (北美) 和 DAB EWS (歐盟)。
AAudio 內建程式庫： AAudio AAudio 支援 OEM 定義的音訊屬性標記，可自訂應用程式行為。例如音訊路徑和音量管理。
電源管理：
- 向內建程序發送電源狀態通知：擴大向 OEM 內建程序 (Android 應用程式以外) 發送電源狀態通知的範圍。
車輛架構：
- 動態設定車輛屬性：支援動態設定車輛屬性的最小值、最大值和支援值。
連線能力
網路：
精簡電話通訊：Android 電話通訊硬體抽象層 (HAL) 的子集，適用於汽車原始設備製造商，可讓原始設備製造商在僅限資料的裝置 (包括 TCU) 上使用 Android 電話通訊。這可減少片段化，並支援電話功能。
連線訊息加購 API：強化 SubscriptionManager，提供可公開使用者行動數據訂閱狀態的 API。例如 active、inactive、trial 和到期日。
投影應用程式支援：新增支援功能，讓車輛原始設備製造商 (OEM) 設定 Android API 無法提供的完整 hostapd.conf 參數。在 SoftApCallback API 中新增中斷連線原因，讓 OEM 瞭解用戶端與本機熱點 (LOHS) 中斷連線的原因。這些功能可改善投影應用程式的支援，並減少片段化。
Android Automotive OS 系統 UI 和體驗
- 可擴充的使用者介面：這個 AAOS 視窗架構提供可設定的元件，讓原始設備製造商滿足視窗需求，並提供自訂體驗。
VHAL 屬性
法規遵循
Android 規範是在內部參考硬體上執行。這個版本執行的測試套件包括 CTS、CTS-V、ATS、STS、VTS 和 CTS on GSI。
除了下列問題，目前沒有已知失敗需要修正 Android 16 程式碼 (android16-release) 或 Android 16 測試分支 (android16-tests-dev)。
測試失敗：
CtsWindowManagerJetpackTestCases#MultiDisplayActivityEmbeddingPlaceholderTests
錯誤摘要：直向螢幕顯示器有一項測試失敗。在以視窗解決方案為基礎的可擴充 UI 建構版本中測試 Activity 嵌入行為時，如果涉及多個根工作 (每個工作都是 WINDOWING_MODE_MULTI_WINDOW)，就會發生已知失敗情形，因為有些活動的啟動範圍小於預期，如嵌入規則中的 windowMetrics 所示。因此，在次要螢幕上啟動活動時，系統會啟動預留位置，導致測試失敗。
aosp/3659633 修補程式可修正多視窗 rootTask 的視窗模式繼承問題。
測試失敗：CtsAutoFillServiceTestCases
失敗摘要：根據涉及多個根工作 (每個根工作都具有以下特徵) 的視窗解決方案，可擴充式 UI 建構版本會發生兩類已知問題：
WINDOWING_MODE_MULTI_WINDOW

For Android 16, this Android Automotive 25Q2 release is compliant. We\ncontinue to fine tune features, aiming to recommend an upcoming release for\nOEMs.\n\nRelease details\n---------------\n\nThis section summarizes major features and enhancements provided in the AAOS B\nrelease.\n\nThese updates apply to `Android16`, [API level 36](/docs/setup/reference/build-numbers).\n\nThe Android Automotive 25Q2 release is compliant with Android 16.\n\n### New features\n\nThe 25Q2 release provides these new features.\n\n#### AAOS Framework\n\n- Audio and radio:\n\n - **Audio control HAL improvements:** To configure car audio features, use\n APIs instead of XML file.\n\n - **High definition (HD) radio Emergency Alert System (EAS):** Pass EAS\n information to radio applications with an API. This applies to HD Radio\n (North America) and DAB EWS (European Union).\n\n - **AAudio built-in library:** [AAudio](/docs/core/audio/aaudio) AAudio supports OEM-defined\n Audio Attributes tags to customize app behavior. For example, audio\n routing and volume management.\n\n- Power management:\n\n - **Power state notifications to built-in processes:** The availability of power state notifications to OEM built-in processes (beyond Android apps) is extended.\n- Car framework:\n\n - **Dynamic configuration of vehicle properties:** Support the dynamic configuration of minimum and maximum and of supported values in vehicle properties.\n\n#### Connectivity\n\n- Networking:\n\n - **Minimal Telephony:** A subset of the Android Telephony Hardware\n Abstraction Layer (HAL) for automotive OEMs to allow OEMs to use Android\n telephony on data-only devices (including TCUs). This reduces\n fragmentation and provides support for telephony functionality.\n\n - **Connectivity Messaging Upsell API:** Enhanced [SubscriptionManager](https://developer.android.com/reference/android/telephony/SubscriptionManager)\n to provide APIs that can expose a user's mobile data subscription\n status. For example, `active`, `inactive`, `trial`, and expiration date.\n\n - **Projected app support:** Added support to let automotive OEMs\n configure the complete set of `hostapd.conf` parameters not available\n through the Android APIs. Added a disconnect reason to the\n SoftApCallback API so that OEMs can learn why clients disconnected from\n a Local Hotspot (LOHS). These features improve support for projected\n apps and reduce fragmentation.\n\n#### AAOS System UI and Experiences\n\n- **Scalable UI:** This AAOS windowing framework provides OEMs with configurable components that let OEMs meet windowing requirements and facilitate custom experiences.\n\n#### VHAL properties\n\n- Vehicle properties:\n\n - Added new vehicle properties to communicate vehicle characteristics and\n state.\n\n - Updated vehicle property constants from @SystemApi to public APIs to\n consolidate generated documentation at [VehiclePropertyIDs](https://developer.android.com/reference/android/car/VehiclePropertyIds). Any\n previously defined and documented permissions are still required to\n access vehicle property data.\n\n- **Third party-accessible vehicle properties:** This features makes eight\n existing vehicle properties relevant to navigation, voice assistant,\n weather, and driving state available to third party app developers. To learn\n more, see [Integrate with Google apps and services](https://developer.android.com/training/cars/index.md#intents).\n\n### Compliance\n\nAndroid Compliance was executed on the internal reference hardware. The test\nsuites run for this release include CTS, CTS-V, ATS, STS, VTS and CTS on GSI.\n\nExcept for the issues listed below, no known failures require a fix either in\nAndroid 16 code (`android16-release`) or to the Android 16 test branch\n(`android16-tests-dev`).\n| **Note:** Fixes for known compliance issues are provided below and will be made available in the [Android Open Source Project](https://android-review.googlesource.com/q/hashtag:%22aaos-25q2-cts%22+(status:open+OR+status:merged)) when we publish the next release. We aim to recommend an upcoming release.\n\n- Test failing:\n `CtsWindowManagerJetpackTestCases#MultiDisplayActivityEmbeddingPlaceholderTests`\n\n Failure summary: One test fails in portrait display. When testing Activity\n embedding behaviors in Scalable UI builds that are based on windowing\n solutions that involve multiple root tasks each a\n `WINDOWING_MODE_MULTI_WINDOW`, known failures occur due to some activities\n launched in smaller bounds than expected, as in `windowMetrics` of the\n embedding rules. As a result, the placeholder was started and the test\n failed when launching an activity on the secondary display.\n\n The [aosp/3659633](https://android-review.googlesource.com/c/platform/frameworks/base/+/3659633) patch corrects windowing mode inheritance from\n multi-window `rootTask`.\n- Test failing: `CtsAutoFillServiceTestCases`\n\n Failure summary: Two categories of known issues occur in the Scalable UI\n builds based on windowing solutions that involve multiple root tasks each of\n `WINDOWING_MODE_MULTI_WINDOW`:\n - IME covers the Autofill fill dialog that prevents the buttons on the\n fill dialog from being pressed. You can temporarily disable the fill\n dialog with this platform [ag/3664131](https://android-review.googlesource.com/c/platform/frameworks/base/+/3664131) patch.\n\n - When the second field is auto-filled, such as `PASSWORD`, the\n `LoginActivity` is behind `decor_grip`, and loses the input focus.\n Patches can be found in the following links: [ag/3679541](https://android-review.googlesource.com/c/platform/packages/services/Car/+/3679541),\n [ag/3675628](https://android-review.googlesource.com/c/platform/frameworks/base/+/3675628), [ag/3675627](https://android-review.googlesource.com/c/platform/frameworks/base/+/3675627)."]]
