// send where details is object

ClassName details = new ClassName();

Intent i = new Intent(context, EditActivity.class);

i.putExtra("Editing", details);

} 

public class MY_CLASS implements Serializable

intent.putExtra("KEY", MY_CLASS_instance);



startActivity(intent);

Intent intent = getIntent();

MY_CLASS class = (MY_CLASS) intent.getExtras().getSerializable("KEY");

MY_CLASS class = (MY_CLASS) intent.getExtras().getParcelable("KEY");
