Pixel 开发者支持图片

{0}

对于 Pixel 6、Pixel 6 Pro 和 Pixel 6a 设备,Android 13 包含用于解决潜在安全漏洞的引导加载程序更新,并且针对这些设备的防回滚计数器递增,以防止此类设备回滚到 Android 12。

为方便应用开发和测试,我们为这些 Pixel 设备提供了经过修改的 Android 12 系统映像(称为开发者支持映像)。开发者支持映像是基于 Android 12(API 级别 31)稳定公开 build 和 12L 功能更新(API 级别 32)的系统映像,其中还包含引导加载程序的更新版本,其中包含安全修复程序和递增的防回滚计数器。

搭载 Android 13 的 Pixel 6、Pixel 6 Pro 或 Pixel 6a 设备可以回滚到 Android 12 开发者支持映像,但无法回滚到任何其他 Android 12 映像。运行开发者支持映像的设备可以刷写到最新的公开 build,但无法刷写回任何之前的 Android 12 映像。

一般公告

开发者支持 build 旨在提供尽可能接近在典型用户设备上运行的 Android 12 行为的系统和应用体验。不过,在使用这些 build 进行开发和测试时,请注意以下事项:

  • 开发者支持 build 仅适用于开发者,不适合一般使用。
  • 使用开发者支持 build 的设备不会像其他设备一样接收 OTA 安全更新,并且开发者支持映像不会使用最新的安全修复程序重新构建。此版本仅包含更新后的引导加载程序版本,此版本包含自己的安全修复程序和递增的防回滚计数器。
  • 开发者支持 build 尚未经过兼容性测试套件 (CTS) 验证,但通过了初步测试,可为开发者提供一组稳定的 API。依赖于经过 CTS 验证的 build 或使用 SafetyNet API 的应用可能无法在 Android 12 开发者支持 build 中正常运行。

刷写设备

您可以通过以下任一方式将 Android 12 开发者支持 build 刷写到设备上:

使用 Android 刷写工具刷写设备

借助 Android 刷写工具,您可以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

通过 USB 连接设备,然后使用以下任一链接导航到 Android 刷写工具,并按照屏幕上的说明操作:

如需查看完整说明,请参阅 Android 刷写工具文档

手动刷写设备

您还可以下载开发者支持映像,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
