依赖

   compile 'org.greenrobot:greendao:3.2.0'
    compile 'com.fynn.fluidlayout:fluidlayout:1.0'

父gradle中添加（对比自己的添加）

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

gradle中添加（对比添加）

greenDao工具类，自己生成bean包，例如：然后点击工具生成类
