Using Parceler with android

Question

I'm trying Parceler library for android. So far I've had only one same error, using plain sample from the documentation.

@Parcel(Parcel.Serialization.BEAN)
public class Example {
  private String name;
  private int age;

  public String getName() { return name; }
  public void setName(String name) { this.name = name; }

  public int getAge() { return age; }
  public void setAge(int age) { this.age = age; }
}

And

Parcelable p = Parcels.wrap(new Example());

Which crashes with

07-30 12:31:46.439: E/AndroidRuntime(4945): FATAL EXCEPTION: main
07-30 12:31:46.439: E/AndroidRuntime(4945): Process: com.sample.app.android.debug, PID: 4945

What do I miss?

Answer 1

It sounds like the annotation processor isn't running or is misconfigured. I'd recommend using the annotationProcessor scope if you're using a Gradle build along with separate scopes for the processor and api libraries:

compile 'org.parceler:parceler-api:1.1.9'
annotationProcessor 'org.parceler:parceler:1.1.9'

See the Getting Parceler section of the website for the latest.

Answer 2

In the newer version, you only have to update the following dependencies in your Gradle file:

compile 'org.parceler:parceler-api:1.1.6'
annotationProcessor 'org.parceler:parceler:1.1.6' 

Answer 3

The error is because of annotation. it works by implementing in build.gradle

annotationProcessor 'org.parceler:parceler:1.1.9'
