OpenCV 4.1.0 Android SDK 无法找到匹配的配置 Android studio

Question

我正在尝试将 OpenCV 4.1.0 Android sdk 导入到我的 android 工作室项目并出现 gradle 构建错误（使用 OpenCV 4.0.1 [=32= 构建成功] 开发工具包）。

Unable to find a matching variant of project :opencv:
  - Variant 'debugApiElements':
      - Required com.android.build.api.attributes.BuildTypeAttr 'release' and found incompatible value 'debug'.
      - Found com.android.build.api.attributes.VariantAttr 'debug' but wasn't required.
      - Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Aar' and found incompatible value 'Apk'.
      - Required org.gradle.usage 'java-runtime' and found incompatible value 'java-api'.
  ...

这是我的应用 build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "ml.nopain.myapplication"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    buildToolsVersion '28.0.3'
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation project(':opencv')
}

还有我的 opencv build.gradle：

apply plugin: 'com.android.application'
android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "org.opencv"
        minSdkVersion 15
        targetSdkVersion 28
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    productFlavors {
    }
}

dependencies {
}

当我尝试导入 OpenCV 4.0.1 Sdk 时，gradle 构建成功且没有任何错误。
我可以尝试做些什么来解决问题？感谢您的帮助！

解决方案 感谢 Ranjan Kumar，我找到了解决这个问题的方法！只需将 'com.android.application' 更改为 'com.android.library'

根据 gradle 看来您正在尝试将 opencv 构建为应用程序。您应该将 opencv 作为模块（库）并包含在您的实际应用程序中。
