レスポンスリスナーが正しく動作しない

Question

私は登録アクティビティとログインアクティビティを持っています。ユーザが正常に登録したときにログインアクティビティを開きたいのですが、私のケースでは登録後にログインアクティビティが得られません。ユーザーはデータベーステーブルに正常に登録されます。 ここはレスポンスリスナーのコードです。

private void registerUser(final String name, final String email, 
          final String password) { 
    // Tag used to cancel the request 
    String tag_string_req = "req_register"; 

    pDialog.setMessage("Registering ..."); 
    showDialog(); 

    StringRequest strReq = new StringRequest(Method.POST, 
      AppConfig.URL_REGISTER, new Response.Listener<String>() { 

     @Override 
     public void onResponse(String response) { 
      Log.d(TAG, "Register Response: " + response); 
      hideDialog(); 

      try { 
       JSONObject jObj = new JSONObject(response); 

       boolean error = jObj.getBoolean("error"); 
       if (!error) { 
        // User successfully stored in MySQL 
        // Now store the user in sqlite 


        JSONObject user = jObj.getJSONObject("user"); 
        String name = user.getString("name"); 
        String email = user.getString("email"); 
        String created_at = user 
          .getString("created_at"); 

        // Inserting row in users table 
        db.addUser(name, email, created_at); 

        Toast.makeText(getApplicationContext(), "User successfully registered. Try login now!", Toast.LENGTH_LONG).show(); 

        // Launch login activity 
        Intent intent = new Intent(
          RegisterActivity.this, 
          LoginActivity.class); 
        startActivity(intent); 
        finish(); 
       } else { 

        // Error occurred in registration. Get the error 
        // message 
        String errorMsg = jObj.getString("error_msg"); 
        Toast.makeText(getApplicationContext(), 
          errorMsg, Toast.LENGTH_LONG).show(); 
       } 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 

     } 
    }, new Response.ErrorListener() { 

     @Override 
     public void onErrorResponse(VolleyError error) { 
      Log.e(TAG, "Registration Error: " + error.getMessage()); 
      Toast.makeText(getApplicationContext(), 
        error.getMessage(), Toast.LENGTH_LONG).show(); 
      hideDialog(); 
     } 
    }) { 

     @Override 
     protected Map<String, String> getParams() { 
      // Posting params to register url 
      Map<String, String> params = new HashMap<String, String>(); 
      params.put("name", name); 
      params.put("email", email); 
      params.put("password", password); 

      return params; 
     } 

    }; 

    // Adding request to request queue 
    AppController.getInstance().addToRequestQueue(strReq, tag_string_req); 
}

## Write the Intent this way ## 
Intent intent = new Intent(
         RegisterActivity.this, 
         LoginActivity.class); 
       RegisterActivity.this.startActivity(intent);
