Check out ObjectBox

Looking for object persistence faster than SQLite? Check out our new mobile database ObjectBox (GitHub).

greenDAO

greenDAO is a light & fast ORM for Android that maps objects to SQLite databases. Being highly optimized for Android, greenDAO offers great performance and consumes minimal memory.

Home page, documentation, and support links: http://greenrobot.org/greendao/

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 <150K and it's just plain Java jar (no CPU dependent native parts)
  • Fast: Probably the fastest ORM for Android, driven by intelligent code generation
  • Safe and expressive query API: QueryBuilder uses property constants to avoid typos
  • Powerful joins: query across entities and even chain joins for complex relations
  • Flexible property types: use custom classes or enums to represent data in your entity
  • Encryption: supports SQLCipher encrypted databases

Add greenDAO to your project

greenDAO is available on Maven Central. Please ensure that you are using the latest versions of the greendao and greendao-gradle-plugin artifact.

Add the following Gradle configuration to your Android project. In your root build.gradle file:

buildscript {
    repositories {
        jcenter()
        mavenCentral() // add repository
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2' // add plugin
    }
}

In your app modules app/build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao' // apply plugin
 
dependencies {
    implementation 'org.greenrobot:greendao:3.2.2' // 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.
