2020-08-12 android studio 4.0 版本

1.项目工程目录结构如下图，是使用Android Studio 4.0新建的library工程：

针对该目录结构的项目，引用libs下的aar方法如下：

• 在该lib工程的build.gradle文件中，新增如下代码:

sourceSets{
    main{
        jniLibs.srcDir(['libs'])
    }
 }

repositories {
     flatDir {
         dirs 'libs'
    }
}

• 直接引用aar即可

dependencies {
    api fileTree(dir: 'libs', include: ['*.jar'])
      api(name: 'oxi_sdk-release', ext: 'aar')
}

• 完整build.gradle代码如下：

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        manifestPlaceholders rootProject.ext.manifestPlaceholders
    }

    sourceSets{
        main{
            jniLibs.srcDir(['libs'])
        }
    }

    repositories {
        flatDir {
            dirs 'libs'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    api fileTree(dir: 'libs', include: ['*.jar'])
    api(name: 'oxi_sdk-release', ext: 'aar')
}
