Android JNI遇到的问题

ndk编译时异常:

D:\java\androidstudio\sdk\ndk-bundle>ndk-build.cmd
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
D:\java\androidstudio\sdk\ndk-bundle\build\\..\build\core\build-local.mk:151: *** Android NDK: Aborting    .  Stop.

解决方法

# ndk-build.cmd后 添加项目路径
D:\java\androidstudio\sdk\ndk-bundle>ndk-build.cmd NDK_PROJECT_PATH=F:\test\face-detection\openCVSamplefacedetection\src\main
