按说明一步步做了，编译时都是类似这样的： pipeline.cpp:function ncnn::Pipeline::destroy(): error: undefined reference to 'vkDestroyPipeline' ..... xxxxxxx.cpp:function ncnn::Pipeline::xxxxxxxx(): error: undefined reference to 'xxxxxxxxxx' 如何解决呢？ image

你是用这个cmake编译的？ https://github.com/nihui/ncnn-android-mobilenetssd/blob/master/app/src/main/jni/CMakeLists.txt

clone 工程后，下载最新的 ncnn-android-vulkan-lib.zip 文件复制到 jni 文件夹，除了修改工程 SDK，NDK，Gradle 的版本外没动其它代码

解决了，vulkan库必须用安卓7.0及以上的手机。
