以 Android 15 的初始版本为基础，我们会不断更新该平台，不断修复问题和改进，然后再面向受支持的设备推出。这些版本通过季度平台版本 (QPR) 每季度发布一次，会作为功能更新的一部分提供给 AOSP 和 Google Pixel 设备。
虽然这些更新不包含影响应用的 API 变更，但我们仍会提供最新 QPR Beta 版 build 的映像，以便您根据需要使用这些 build 来测试您的应用（例如，如果有即将推出的功能可能会影响应用的用户体验）。
如需查找适用于已经发布的该平台稳定版本的出厂映像，请参阅适用于 Nexus 和 Pixel 设备的出厂映像。
如果您是使用受支持的 Google Pixel 设备的开发者，则可以手动将该设备更新到最新 build 以进行测试和开发。刷写出厂映像需要完全重置设备，因此请务必先备份数据。build 适用于以下 Pixel 设备：
- Pixel 6 和 Pixel 6 Pro
- Pixel 6a
- Pixel 7 和 Pixel 7 Pro
- Pixel 7a
- Pixel Fold
- Pixel Tablet
- Pixel 8 和 Pixel 8 Pro
- Pixel 8a
- Pixel 9、Pixel 9 Pro、Pixel 9 Pro XL 和 Pixel 9 Pro Fold
使用以下链接和说明将受支持的设备更新到最新版本。如需寻求其他方式来获取适用于测试和开发的 QPR1，请参阅获取 Android 15 QPR Beta 版 build。
使用 Android 刷写工具刷写设备
Android 刷写工具可让您将系统映像安全地刷写到受支持的 Pixel 设备上。Android 刷写工具可以在任何支持 WebUSB 的网络浏览器（如 Chrome 或 Edge 79 及更高版本）上使用。
Android 刷写工具会引导您逐步完成设备刷写过程。您无需安装工具，但需要解锁设备，并在开发者选项中启用 USB 调试。如需查看完整说明，请参阅 Android 刷写工具文档。
通过 USB 连接设备，然后使用以下链接访问 Android 刷写工具，并按照屏幕上的说明操作：https://flash.android.com/preview/vic-qpr1-beta2。
手动刷写设备
您还可以下载最新的系统映像，并手动将其刷入您的设备。请参见下表，下载适合您的测试设备的系统映像。如果您需要精确控制测试环境或者需要经常重新安装（例如，在执行自动测试时），手动刷写设备会非常有用。
在备份设备数据并下载以下匹配的系统映像后，您就可以将映像刷入设备。
您可以随时选择还原为最新的公开版 build。
