Example:

public class City implements Serializable {

private List<House> house;

public List<House> getHouse() {
    return house;
}

public void setHouse(List<House> house) {
    this.house = house;
}}

Then House needs to implements Serializable as so :

public class House implements Serializable {

private String name;

public String getName() {
    return name;
}

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

Then you can pass city like below:

Bundle bundle = new Bundle();
bundle.putSerializable("city", city);
intent.putExtras(bundle);

And retreive it with:

Intent intent = this.getIntent();
Bundle bundle = intent.getExtras();
City city =  (City)bundle.getSerializable("city");

You can use this

   ModelObject myObj= new ModelObject();
    Gson gson = new Gson();
    String json = gson.toJson(myObj);

    Intent intentSecond = new Intent(this,ThirdActivity.class);
        intentSecond.putExtra("game",json);
        startActivity(intentSecond);

You can convert model to gson and on another page you can convert gson to model

ModelObject myObj= new Gson().fromJson(getIntent().getStringExtra("game"), ModelObject.class);
