AutoParcel is an AutoValue extension that enables Parcelable values generation.

Just add implements Parcelable to your @AutoValue annotated models.

@AutoValue
abstract class Person implements Parcelable {
  abstract String name();
  abstract List<Address> addresses();
  abstract Map<Person, Integer> likes();

  static Person create(String name, List<Address> addresses, Map<Person, Integer> likes) {
    return new AutoValue_Person(name, addresses, likes);
  }
}

That's that simple. And you get Parcelable, hashCode, equals and toString implementations for free.

As your models evolve you don't need to worry about keeping all the boilerplate in sync with the new implementation, it's already taken care of.

Use the same dependency qualifier that you would use for AutoValue (e.g. apt)

buildscript {
  repositories {
    mavenCentral()
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
  }
}

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

repositories {
  mavenCentral()
  jcenter()
  maven {url "https://clojars.org/repo/"}
}

dependencies {
  apt 'frankiesardo:auto-parcel:{{latest-version}}'
}

Notice the clojars line in your maven repositories

I recommend using the android-apt plugin so that Android Studio picks up the generated files. Check out the sample project for a working example.
