Retrofit 2 + AutoValueGson

Just try to use Google AutoValue on one of my existing open source project, the steps are basically as below.

Before Apply: A simple UserBean with GitHubService.

public interface GitHubService {
    String BASE_URL = "https://api.github.com/";

    @GET("users")
    Observable<List<UserBean>> getUserList();
}
public class RetrofitHelper {
    public GitHubService newGitHubService() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(GitHubService.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();
        return retrofit.create(GitHubService.class);
    }
}
public class UserBean {
    public String login;
    public int id;
    public String avatarUrl;
}

After Apply: It need to provide two libraries AutoValue & AutoValueGson, and the UserBean with @AutoValue annotation.

dependencies {
    annotationProcessor "com.google.auto.value:auto-value:1.2"
    annotationProcessor "com.ryanharter.auto.value:auto-value-gson:0.4.5"
    provided "com.google.auto.value:auto-value:1.2"
    provided "com.ryanharter.auto.value:auto-value-gson:0.4.5"
}
public interface GitHubService {
    String BASE_URL = "https://api.github.com/";

    @GET("users")
    Observable<List<UserBean>> getUserList();
}
@GsonTypeAdapterFactory
public abstract class RetrofitGsonTypeAdapterFactory implements TypeAdapterFactory {
    public static TypeAdapterFactory create() {
        return new AutoValueGson_RetrofitGsonTypeAdapterFactory();
    }
}
public class RetrofitHelper {
    public GitHubService newGitHubService() {
        Gson gson = new GsonBuilder()
                .registerTypeAdapterFactory(RetrofitGsonTypeAdapterFactory.create())
                .create();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(GitHubService.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();
        return retrofit.create(GitHubService.class);
    }
}
@AutoValue
public abstract class UserBean {
    public abstract String login();

    public abstract int id();

    @Nullable
    public abstract String avatarUrl();

    public static UserBean create(String login, int id, @Nullable String avatarUrl) {
        return new AutoValue_UserBean(login, id, avatarUrl);
    }

    public static TypeAdapter<UserBean> typeAdapter(Gson gson) {
        return new AutoValue_UserBean.GsonTypeAdapter(gson);
    }
}

The full project can be found at GitHub.
