Android - Comment transmettre des données supplémentaires avec l'intention de ListFragment?

Question

Je reçois une erreur quand je veux transférer une chaîne en utilisant "intenet mis extra", il semble que la deuxième activité tombe en panne livré

MainActivity

{

Conversation conversationForUserList = pagerAdapter.getItem(pager.getCurrentItem()); 


    if (conversationForUserList.getType() == Conversation.TYPE_CHANNEL) {     
     Intent intent = new Intent(this, SecondActivity.class); 
     intent.putExtra(
       Extra.USERS, 
       binder.getService().getConnection(server.getId()).getUsersAsStringArray(conversationForUserList.getName())); 
     startActivityForResult(intent, REQUEST_CODE_USERS); 
    } else { 
     Toast.makeText(this, getResources().getString(R.string.only_usable_from_channel), Toast.LENGTH_SHORT).show(); 

AbrirLista()

public void

}

drawerLayout.openDrawer(drawerView); 
} 

SecondActivity

public class SecondActivity extends ListFragment { 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     final String[] users = getActivity().getIntent().getExtras().getStringArray(Extra.USERS); 
     ListAdapter myListAdapter = new ArrayAdapter<String>(getActivity(), 
       android.R.layout.simple_list_item_1, users); 
     setListAdapter(myListAdapter); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     return inflater.inflate(R.layout.list, container, false); 
    } 


}

Conversation conversationForUserList = pagerAdapter.getItem(pager.getCurrentItem()); 
    Intent intent = new Intent(this, SecondActivity.class); 
    intent.putExtra("name_id",conversationForUserList); 
    startActivity(intent); 

    // get data to SecondActivity.class 
    private Context context; 
    private Conversation userList; 
    private ArrayList<Conversation> users; 
    userList = (Conversation) getActivity().getIntent().getSerializableExtra("name_id"); 
    users=conversationForUserList.getName(context); 

    ListAdapter myListAdapter = new ArrayAdapter<String>(getActivity(), 
      android.R.layout.simple_list_item_1, users); 
     setListAdapter(myListAdapter);
