Крэш при попытке обращения к URL

[BlizzedRu]

Всем привет! Помогите, пожалуйста. Данный код успешно работает в обычной Java, а вот помещая его в приложение Android, оно крэшится.
Вообще при вызове метода getRestory приложение вылетает

public static String getRestory(String pageAddress, String codePage) throws Exception {
        StringBuilder sb = new StringBuilder();
        URL pageURL = new URL(pageAddress);
        URLConnection uc = pageURL.openConnection();
        BufferedReader br = new BufferedReader(
                new InputStreamReader(
                        uc.getInputStream(), codePage));
        try {
            String inputLine;
            while ((inputLine = br.readLine()) != null) {
                sb.append(inputLine);
            }         
        } finally {
            br.close();
        }
        return sb.toString();
    }
      
   
    public void click_refresh(View v) throws Exception{
        TextView story_text = (TextView)findViewById(R.id.story_text);
        ImageButton refresh = (ImageButton)findViewById(R.id.button_refresh);
        
        Animation animation = null;
        animation = AnimationUtils.loadAnimation(this, R.anim.rotation);
                
        refresh.startAnimation(animation);
        String restory = getRestory("http://sdsd","UTF8");
        story_text.setText(restory);
                      
    }

Ладно, спасибо. Пришлось использовать чужой код. http://stackoverflow.com/questions/1441 ... -to-string

Caused by: android.os.NetworkOnMainThreadException

Это означает, что вы ведете работу с сетью в основном потоке, а так нельзя - нужно обязательно организовывать дополнительный поток. (код я не смотрела).

[altwin]

я знаю секрет.

[missing]

Нужно вынести код обращения к серверу в отдельный поток, воспользуйтесь AsyncTask или Servece. (код тоже не читал )
