DaoCompat: greenDAO on ObjectBox

Using greenDAO? Keep the greenDAO API and use ObjectBox instead of SQLite for an extra boost. ObjectBox is a superfast object-oriented database with strong relation support.

DaoCompat = greenDAO - SQLite + ObjectBox

Using DaoCompat, you can easily switch to ObjectBox. Of course, this depends on your use of SQL/SQLite features because ObjectBox is a NoSQL database.

Gradle setup

You should start with the basic ObjectBox set up: check its GitHub page and intro. Additionally, you need to enable the objectbox.daoCompat flag via annotation processor options, and add DaoCompat as a dependency. In the end, your app build.gradle should have those additions:

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

android {
    defaultConfig {
         javaCompileOptions {
            annotationProcessorOptions {
                arguments = ['objectbox.daoCompat': 'true']
            }
        }
    }
}

dependencies {
    compile "org.greenrobot:objectbox-daocompat:1.1.0"
}

First steps

To create the greenDAO-like DaoSession, you need an instance of BoxStore from ObjectBox. You typically initialize those objects once for your app, e.g. in onCreate in your Application class:

boxStore = MyObjectBox.builder().androidContext(this).build();
session = new DaoSession(boxStore);

With the DaoSession you are already in your well-known greenDAO API territory. For example, you can get DAOs using session.getMyEntityDao() and then call methods like insert(...) or load(...).
