您的构建。gradle使用了一个旧模板,与Android Studio 3不相关,而且,您可能合并了两个源代码,这两个源代码相互矛盾

然而,眼前的问题是,您的ndkBuild是为Windows构建的,如果您只是删除
.cmd
,您的脚本可能在Ubuntu上工作。但让我们把它清理一下:

apply plugin: 'com.android.application'

android {
  compileSdkVersion 26
  defaultConfig {
    applicationId "com.test.opencv"
    minSdkVersion 15
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    ndk {
      abiFilters 'armeabi-v7a'
    }
  }

  externalNativeBuild {
    ndkBuild {
      path "src/main/jni/Android.mk"
    }
  }

  buildTypes {
    release {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }

  dependencies {

    implementation project(':openCVLibrary249')
  }
}

这假设
:openCVLibrary249
配置正确。
