解决办法：

1.验证并修复 NDK 安装

• 检查 NDK 目录

        打开C:\Users\Administrator\AppData\Local\Android\Sdk\ndk\27.1.12297006，确认是否存在 source.properties 文件。若缺失，需重新安装或更新 NDK。

• 通过 Android Studio 安装 NDK
  打开 Android Studio → SDK Manager → SDK Tools → 勾选 NDK (Side by side)，选择稳定版本（如 25.x 以上），完成安装

2. 配置 NDK 版本（关键）

在项目的 android/app/build.gradle 中指定兼容的 NDK 版本：

android {
    ndkVersion "25.2.9519653"  # 根据实际安装版本修改
}
