添加库时出现UnsatisfiedLinkError

Question

我正在尝试添加this库并运行应用程序，但是当触发Intent以启动Markerless_Wall活动时，会显示以下错误：

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.mproga1nagindergupta.kundan_public-1/base.apk"],nativeLibraryDirectories=[/data/app/com.example.mproga1nagindergupta.kundan_public-1/lib/x86, /vendor/lib, /system/lib]]] couldn't find "libKudan.so"
