Replace your class with this

public class UploadDataGetter implements Serializable {

    @SerializedName("record_id")
    private int id;

    @SerializedName("full_name")
    private String name;

    @SerializedName("full_address")
    private String address;

    @SerializedName("contact")
    private String contact;

    @SerializedName("dilivery_place")
    private String dplace;

    @SerializedName("dilivery_place")
    private String fdetails;

    @SerializedName("no_of_normal")
    private int noOfNormal;

    @SerializedName("no_of_classified")
    private int noOfClassified;

    @SerializedName("no_of_cds")
    private int noOfCds;


    public UploadDataGetter(
            //constuctor's para
            int record_id,
            String full_name,
            String full_address,
            String contact_number,
            String dilivery_place,
            String further_details,
            int no_of_normal,
            int no_of_classified,
            int no_of_cds

    ) {
        id = record_id;
        name = full_name;
        address = full_address;
        contact = contact_number;
        dplace = dilivery_place;
        fdetails = further_details;

        noOfNormal = no_of_normal;
        noOfClassified = no_of_classified;
        noOfCds = no_of_cds;

        String img_collector;
        String dilivery_status;
        double geo_long;
        double geo_lat;

    }

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getContact() {
        return contact;
    }

    public void setContact(String contact) {
        this.contact = contact;
    }

    public String getDplace() {
        return dplace;
    }

    public void setDplace(String dplace) {
        this.dplace = dplace;
    }

    public String getFdetails() {
        return fdetails;
    }

    public void setFdetails(String fdetails) {
        this.fdetails = fdetails;
    }

    public int getNoOfNormal() {
        return noOfNormal;
    }

    public void setNoOfNormal(int noOfNormal) {
        this.noOfNormal = noOfNormal;
    }

    public int getNoOfClassified() {
        return noOfClassified;
    }

    public void setNoOfClassified(int noOfClassified) {
        this.noOfClassified = noOfClassified;
    }

    public int getNoOfCds() {
        return noOfCds;
    }

    public void setNoOfCds(int noOfCds) {
        this.noOfCds = noOfCds;
    }
}

now send this to new activity in intent like this

Intent intent=new Intent(this, NewActivity.class);
int.putExtra("data", YOUR_UPDATE_DATA_GETTER_OBJECT);

Now get the object in the new activity like this

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class NewActivity extends Activity {


    private UploadDataGetter dataGetter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent=getIntent();
        if(intent.hasExtra("data")){
            dataGetter= (UploadDataGetter) intent.getSerializableExtra("data");
            Log.d("NewActivity","ID: "+dataGetter.getId());
        }
    }
}
