dlopen failed: library “libopencv_java4.so“ not found 解决

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 ""
     
    
   

    

     

    
    

     

      //
