dlopen failed: library "libopencv_java4.so" not found

Android studio编译yolov5时报错，

最后解决方法：

app所在目录的build.gradle修改：

指向opencv 的库arm64-v8a所在的父目录，报错就解决了。

externalNativeBuild {
        cmake {
            version "3.10.2"
            path file('src/main/jni/CMakeLists.txt')
        }
    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['src/main/jni/opencv']  // libs
        }
    }

build.gradle完整代码：

apply plugin: 'com.android.application'
android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.tencent.yolov5ncnn"
        archivesBaseName = "$applicationId"
        externalNativeBuild {
            cmake {
                cppFlags ""
//
