为了删除此错误，我对build.gradle进行了如下更改：

apply plugin: 'com.android.application'

android {
compileSdkVersion 28
//buildToolsVersion "29.0.0"
defaultConfig {
    applicationId "com.example.opencvdemo"
    minSdkVersion 19
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    ndk {
        abiFilters "armeabi-v7a", "x86", "armeabi", "mips"
    }
    externalNativeBuild {
        cmake {
            cppFlags "-frtti -fexceptions"
        }
    }
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }

}

sourceSets {
    main {
        jni.srcDirs = ['src/main/jniLibs']
        jniLibs.srcDir 'src/main/libs'
     }
   }
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar','*.so'])
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.intuit.sdp:sdp-android:1.0.6'
implementation 'com.intuit.ssp:ssp-android:1.0.6'

implementation 'com.github.bumptech.glide:glide:3.7.0'
implementation 'com.github.markushi:circlebutton:1.1'

}
现在我得到了这个错误：

根据堆栈跟踪：java.lang.unsatifiedLinkError:dlopen失败：“/data/app/com.example.opencvdemo-o8BNe1NoZik-avIk3otJaw==/lib/arm64/libjniopencv_contrib.so”是32位而不是64位的

因此，我假设您的库没有用于arm64-v8a的资源，要解决此问题，您必须将用于arm64-v8a的.So文件添加到您的项目opencv中。

在jniLibs目录中创建一个名为arm64-v8a的文件夹并复制这些文件。那么这些文件会有帮助吗？您能告诉我jniLibs文件夹中有哪些FLORDERS和文件吗？好的，现在，请确保您的arm64-v8a文件夹中有一个名为“libjniopencv_contrib.so”的文件，如果它在那里，那么您能告诉我您的“lib”文件夹中有哪些文件吗？
