【问题描述】：

我正在尝试运行这个项目 https://github.com/eyetrackingDB/GazeTrackingFramework

我安装了 Android Studio 2.3.3、NDK 15.1.4119039、Gradle 版本 3.3 和 Android 插件版本 2.3.3。

编译 SDK 版本：API 21：Android 5.0 (Lollipop) 构建工具版本：26.0.1 最低 SDK 版本：API 19：Android 4.4 (KitKat) 目标 SDK 版本：API 21：Android 5.0 (Lollipop)

我是否遗漏了什么或版本不兼容，因为这应该是一个简单的应用程序。

【解决方案1】：

尝试重新安装您的 NDK。可能您的 NDK 安装已损坏。转到 SDK 管理器并导航到 Appearance & Behavior/System Settings/Android SDK。

在选项卡菜单中选择 SDK 工具并取消选择 NDK checkbox -> Apply。卸载后 -> 标记 NDK 并再次应用。

这解决了我的问题，我希望它也能帮助你。
