首先 建立一个项目 吧那个C++啥的勾上 然后当前Moudlegradle配置

      apply plugin: 'com.android.application'

 android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.example.a15735.test"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    externalNativeBuild {
        cmake {
            cppFlags ""
            abiFilters 'arm64-v8a', 'armeabi-v7a'
        }
    }
     }
    buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
externalNativeBuild {
    cmake {
          //这里选你复制在jni 文件下的自带的CMakeLists.txt
        path "src/main/jni/CMakeLists.txt"
    }
}
  }

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
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'

}
