在您的项目中添加greenDAO

greenDAO在Maven中心提供。请确保您正在使用最新的版本，检查这里和这里

在你的Android项目中添加以下等级配置:

Add greenDAO to your project

greenDAO is available on Maven Central. Please ensure that you are using the latest versions by checking here and here

Add the following Gradle configuration to your Android project:

// 在你的根。gradle文件: 【】In your root build.gradle file:
buildscript {
    repositories {
        jcenter()
        mavenCentral() // add repository
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2' // add plugin
    }
}
 
//在你的应用程序项目中。gradle文件:【】 In your app projects build.gradle file:
apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao' // apply plugin
 
dependencies {
    compile 'org.greenrobot:greendao:3.2.2' // add library
}
=====

请注意，这将把greenDAO Gradle 插件连接到您的构建过程中。
当您构建您的项目时，它会生成诸如DaoMaster、dao会话和DAOs之类的类。

Note that this hooks up the greenDAO Gradle plugin to your build process. When you build your project, it generates classes like DaoMaster, DaoSession and DAOs.
