        this.name=name;

Answer 1

You have to make BeanClass class to serializable.

public class BeanClass implements Serializable
{
  //fields
  //constructors
  //setter/getter 
}

Prepare the List and pass it via Intent.putExtra()

 Intent intent=new Intent(MainActivity.this, NextActivity.class);
 ArrayList<BeanClass> list=new ArrayList<BeanClass>();
 list.add(new BeanClass(nm, Add, Phn));
 ...

 intent.putExtra("list", list); 
 startActivity(intent);

And receive the List in NextActivity's onCreate method

 Intent intent=getIntent();
 ArrayList<BeanClass> list=(ArrayList<BeanClass>)intent.getSerializableExtra("list");
