Acorn is tactically divided in several modules to be able to separate different concerns from each other. Core artifacts define the general contracts of Acorn, while extension artifacts provide the implementations.

Easy setup

Acorn is hosted on Maven Central.

To get started quickly, you can include the ext-acorn-android dependency, which includes the necessary base to create an app.

1 implementation "com.nhaarman.acorn.ext:acorn-android:x.x.x"

If you use androidx.appcompat, you can use ext-acorn-android-appcompat instead:

1 implementation "com.nhaarman.acorn.ext:acorn-android-appcompat:x.x.x"

Using the dependencies above will transitively pull all other dependencies you need as well.

Advanced setup

As mentioned before, Acorn is divided in several modules.

Core

The core modules provide the general contracts of Acorn as interfaces and simple data classes.

JVM extensions

The following artifacts build upon the acorn artifact and provide some default implementations for Navigator and Scene:

Android extensions

The following artifacts provide the necessary implementations to make Acorn work on Android:

Experimental features

Experimental features live in a separate artifact.
