}

I tried to send the object via intent as the following method

private ArrayList<ProductListDataModel> productList;

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

But this causes the app to crash. The error I get on crashing is

"UncaughtException:     
at android.support.v4.app.FragmentActivity.startActivityForResult(FragmentActivity.java:751)
            at android.app.Activity.startActivity(Activity.java:4800)"

I have created the model class by using jsonschema2pojo online. Any one please suggest me a solution.

do these changes

implement Serializable in your model class.

 public class ProductListDataModel  implements Serializable{

    //your rest code 

    }

You must implement with parcelable, once you implemented it, you have to add implemented methods in your model class, which automatically generates by android studio.

And then send your object in intent like this way

    Intent intent = new Intent(this,CallFragmentOrActivity.class);
    intent.putParcelableArrayListExtra("data", productList);
    getActivity().setResult(Activity.RESULT_OK, intent);
    getActivity().finish();

And then get your parcelable object in your called activity or fragment

    Intent intent = getActivity().getIntent();
    if (intent != null) {
        yourProductListObject = intent.getParcelableArrayListExtra("data");
    }

I hope this will help you :)

implement Serializable or Parcelable in you ProductListDataModel

for eg:

public class ProductListDataModel implements Serializable{ 


// your code

}

or By using Parcelable :

import android.os.Parcel;
import android.os.Parcelable;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

import java.util.List;

public class ProductListDataModel implements Parcelable {

    @SerializedName("id")
    @Expose
    private Integer id;


    protected ProductListDataModel(Parcel in) {
        if (in.readByte() == 0) {
            id = null;
        } else {
            id = in.readInt();
        }
    }

    public static final Creator<ProductListDataModel> CREATOR = new Creator<ProductListDataModel>() {
        @Override
        public ProductListDataModel createFromParcel(Parcel in) {
            return new ProductListDataModel(in);
        }

        @Override
        public ProductListDataModel[] newArray(int size) {
            return new ProductListDataModel[size];
        }
    };

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }



    @Override
    public String toString() {
        return "ProductListDataModel{" +
                "id=" + id +

                '}';
    }

    @Override
    public int describeContents() {
        return hashCode();
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        if (id == null) {
            dest.writeByte((byte) 0);
        } else {
            dest.writeByte((byte) 1);
            dest.writeInt(id);
        }

    }
}

not working. app crases again. "UncaughtException: java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.myapp.test.model.model_product_list.ProductListDataModel) at android.os.Parcel.writeSerializable" — visakh r, Dec 21 '18 at 06:54
when implementing parcelable, recycleradapter binding not working. — visakh r, Dec 21 '18 at 07:32
