每個版本發布時，特定 Android API 可能會過時，或需要重構，才能提供更優質的開發人員體驗或支援新的平台功能。在這種情況下，我們會正式淘汰過時的 API，並引導開發人員改用其他 API。
淘汰表示我們已停止提供 API 的官方支援，但開發人員仍可繼續使用。本頁面列出這個 Android 版本中一些值得注意的淘汰項目。如要查看其他淘汰項目，請參閱 API 差異比較報表。
改用 Spatializer 而非 Virtualizer
First added in Android 12 (API level 32), the Spatializer
class lets apps query the capabilities and behavior of sound spatialization on
the device. In Android 15, the Virtualizer class is
deprecated. Use
AudioAttributes.Builder.setSpatializationBehavior instead
to characterize how you want your content to be played when spatialization is
supported.
AndroidX media3 ExoPlayer 1.0 enables spatial audio by default for multichannel audio when the device supports it. See this recent blog post and the spatial audio documentation for more information, including APIs to control the feature.
Android WebView 中的 WebSQL 已淘汰
The setDatabaseEnabled and getDatabaseEnabled
methods from WebSettings are now deprecated. These settings activated support
for WebSQL inside Webview. WebSQL is now removed in Chrome and is now deprecated
on Android Webview. These methods will become a no-op on all Android versions in
the next 12 months.
The World Wide Web Consortium (W3C) encourages apps needing web databases to adopt Web Storage API technologies like localStorage and sessionStorage, or IndexedDB. SQLite Wasm in the browser backed by the Origin Private File System outlines a replacement set of technologies based on the SQLite database, compiled to Web Assembly (Wasm), and backed by the origin private file system to enable more direct migration of WebSQL code.
