JSON Parcelable

This simple library provides basic parcelization functionality on pojo objects. Serialization to parcel, bases on Json serialization (thanks to Jackson Serializer):

Writing to parcel works in two main steps:

• Object is serialized to json string
• json string is written to parcel

It isn't as fast as standard method but is fast enough for today's smartphones. End-user will not notice any difference.

Usage is simple as possible. Any thing what you need to do, is extend JsonParcelable class in your pojo object and provide blank constructor without parameters, look at example above.

public class SimplePojo extends JsonParcelable {
  private int integer;
  private boolean bool;
  private String string;
  private ArrayList<String> strings;
  
  public SimplePojo() {
  }
  
  public SimplePojo(int integer, boolean bool, String string, ArrayList<String> strings) {
    this.integer = integer;
    this.bool = bool;
    this.string = string;
    this.strings = strings;
  }
  
  public int getInteger() {
    return integer;
  }
  ...
}

Usage examples

• write to Bundle

simplePojo.putJsonParcelable(bundle) ;

• or Intent

simplePojo.putJsonParcelable(intent);

• read from bundle

simplePojo = JsonParcelable.GetJsonParcelable(SimplePojo.class, bundle);

• Because serialization is based on json you can serialize object to json string

simplePojo.serialize();

• inflate existing object

simplePojo.inflate(jsonString);

• or create new from jsonString

simplePojo = JsonParcelable.Deserialize(SimplePojo.class, jsonString);

Android Studio hint

If you work with AndroidStudio you should disable lint inspection for missing CREATOR in classes that implements Parcelable. JsonParcelable class already provide CREATOR and you shouldn't care about it.
