Problem in integrating twitter with android

I want to integrate twitter to my android app for that I have referred link

I have used the code for my main activity`Twitter my_twiter;

Button btn_login;
EditText edit_user_name;
EditText edit_password;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    btn_login = (Button) findViewById(R.id.main_loin_button);
    edit_user_name = (EditText) findViewById(R.id.main_username_edit_text);
    edit_password = (EditText) findViewById(R.id.main_password_edit_text);

    btn_login.setOnClickListener(this); 
}

@SuppressWarnings("deprecation")
@Override
public void onClick(View v) 
{开发者_开发问答
    String userName = edit_user_name.getText().toString();
    String password = edit_password.getText().toString();
    my_twiter = new Twitter(userName,password);
    if(my_twiter == null)
    {
     Toast.makeText(TwitActivty.this, "Incorrect Login",Toast.LENGTH_LONG).show();
    }
    else 
    {
//          Toast.makeText(TwitActivty.this, "Worked",Toast.LENGTH_LONG).show();
        try
        {
         Log.i("Twitter Status :",my_twiter.getStatus()+"");
         Intent intent = new Intent(TwitActivty.this,Twitter_Info_Activity.class);
         startActivity(intent);
        }
        catch(Exception e)
        {
           e.printStackTrace();
        }
        }
    }`
