Features
--------
greenDAO's unique set of features:

 Rock solid: greenDAO has been around since 2011 and is used by countless famous apps
 Super simple: concise and straight-forward API, in V3 with annotations
 Small: The library is '
        classpath 'org.greenrobot:greendao-gradle-plugin:3.3.1' // add plugin
    }
}

In your app modules app/build.gradle file:
groovy
apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao' // apply plugin
 
dependencies {
    implementation 'org.greenrobot:greendao:3.3.0' // add library
}


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.
