Auto-value-bundle

An extension for Google's AutoValue that supports Android Bundle object.

Motivation

Bundles are used to pass data along with intents and services, between activities, and from GCM, among other reasons. However, converting that data from a bundle to a Java object involves a lot of repetitive and error-prone code.

Download

Add Gradle dependency:

dependencies {
  annotationProcessor "com.google.auto.value:auto-value:1.4.1"
    annotationProcessor "com.uber.autovalue-bundle-extension:1.0.0"
    //Optionally for use of @GCMBundle annotation
    provided "com.uber.autovalue-bundle-extension:1.0.0"
}

Usage

Simply include the Autovalue: Bundle Extension in your project and add a constructor to your abstract value class that calls the unbundle method.

@AutoValue
public abstract class Foo {

    public static Foo create(Bundle bundle, Gson gson) {
        return AutoValue_Foo.unbundle(bundle, gson);
    }

    public abstract String bar();
}

GCM Bundle

Additionally, there is an annotation @GCMBundle which is used to denote that a bundle was created and attached to an intent from GCM. This means that the data is stored in String-String key-value pairs. Using the @GCMBundle annotation will infer the type from the return type of the value class methods and handle the conversion and type casting for you.

@AutoValue
@GCMBundle
public abstract class Foo {

    public static Foo create(Bundle bundle, Gson gson) {
        return AutoValue_Foo.unbundle(bundle, gson);
    }

    public abstract int bar();
}
