随着每个版本的发布，特定的 Android API 可能会过时或需要进行重构，以提供更好的开发者体验或支持新的平台功能。在这些情况下，我们会正式废弃过时的 API，并引导开发者改用替代 API。
废弃意味着我们已结束对这些 API 的正式支持，但开发者仍可继续使用它们。本页重点介绍此 Android 版本中废弃的一些重要 API。如需查看废弃的其他 API，请参阅 API 差异报告。
使用 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 中已废弃 WebSQL
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.
