ObjectBox Java (Kotlin, Android)

ObjectBox is a superfast object-oriented database with strong relation support.

Latest version: 1.4.1 (2018/01/23)

Demo code using ObjectBox:

Playlist playlist = new Playlist("My Favorties");
playlist.songs.add(new Song("Lalala"));
playlist.songs.add(new Song("Lololo"));
box.put(playlist);

Gradle setup

Add this to your root build.gradle (project level):

buildscript {
    ext.objectboxVersion = '1.4.1'
    repositories {
        maven { url "http://objectbox.net/beta-repo/" }
    }
    dependencies {
        classpath "io.objectbox:objectbox-gradle-plugin:$objectboxVersion"
    }
    
}
    
allprojects {
    repositories {
        maven { url "http://objectbox.net/beta-repo/" }
    }
}

And this to our app's build.gradle (module level):

apply plugin: 'io.objectbox' // after applying Android plugin

First steps

Prepare the BoxStore object once for your app, e.g. in onCreate in your Application class:

boxStore = MyObjectBox.builder().androidContext(this).build();

Create data object class @Entity, for example "Playlist". Then get a Box class for this entity class:

Box<Playlist> box = boxStore.boxFor(Playlist.class);

The Box object gives you access to all major functions, like put, get, remove, and query.
