When I try to pass object with intent it crashes my application

The application works well when I do not use putExtra with intent, but when I use putExtra and passes the object it crashes. I also tried implementing Serializable in HumLogController class (object of which I want to pass). Also the results are same with parceable, i.e. it crashes. 

package com.example.praduman.humlog;

import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.os.Parcelable;
import android.support.v4.app.FragmentActivity;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import com.parse.Parse;
import java.io.Serializable;

public class HomeActivity extends ActionBarActivity {

    private HumLogController humLogController;
    private Intent logInActivityIntent;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        humLogController = new HumLogController();      


        logInActivityIntent = new Intent(this , LogInActivity.class);
        logInActivityIntent.putExtra("my object", (Serializable) humLogController);
        startActivity(logInActivityIntent);
    }


}

The activity log is:- The thing is it do not crash when I do not use putExtra. Can any one help ..? Below is the log cat in android studio. As I said I tried implementing both Serializable and Parceable but non of them works.

The above errors happen when I do not implement Serilizable in HumLogController and just cast the object in the object, while passing through the intent. Below is the code of HumLogController class when I also implements Serializable there.

package com.example.praduman.humlog;

import java.io.Serializable;

/**
 * Created by Praduman on 23/07/2015.
 */
public class HumLogController implements Serializable{
   private HumLogModel humLogModel ;
    private String username;
    private String password;
    private String userType;

    public HumLogController() {
        this.humLogModel = new HumLogModel();
    }
    public void createNewUser(){
        humLogModel.createNewUser(getUsername(), getPassword());
    }

    public void setUserEssentials(String username,String password, String userType){
        setUsername(username); setPassword(password); setUserType(userType);
    }

    public void setUsername(String username){
        this.username = username;
    }
    public void setPassword(String password){
        this.password = password;
    }
    public void setUserType(String userType){
        this.userType = userType;
    }

    public String getUsername(){
        return username;
    }
    public String getPassword(){
        return password;
    }
    public String getUserType(){
        return userType;
    }
}

The logcat when I implements serializable in HumLogContoller class is given below.

If you have a custom Serializable class like HumLogController, you have to make sure that all its fields are Serializable as well, or declare them transient if you don't want to serialize them. In your case, HumLogModel is not Serializable.
