Answer 1

从项目的顶层目录中运行ndk-build，而不是像您所做的那样从C:\运行。否则，它将无法在项目的jni部分中找到文件，如您所见：

Android NDK: Looking for AndroidManifest.xml in C:
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.

这表明您还可以选择设置NDK_PROECT_PATH环境变量，作为告诉工具在哪里可以找到您的项目的替代方法。然而，unix风格的环境变量通常是Windows上的麻烦来源，至少在历史上，Windows的默认环境大小很小。
