解决方案

我想你想下载HTML code在UI线程。尝试下载它在后台运行，使用 AsynkTask

编辑。如果你说，它适用于Android 2.2，但它并没有在Android 4.0 / 3.0工作我完全确定您要下载它的UI线程。从Android 3.0的，你不能做长期的过程在UI线程因为你可以阻止它。你必须做的下载在不同的线程


PS。对不起，我的英语水平。

I found this code from here download html source android? . But when I try running it, my program keeps crashing. I have already added the internet permission in. Any ideas?

Edit: Here is the full error message. 08-02 00:16:47.364: E/EmbeddedLogger(1577): Error getting package label: com.jimmyc.lawrenceh.schedulinglookup

Edit2: It works on Android 2.2 but it doesn't work on Android 4.0/3.0.

 private void initialize() {
      //initialize variables here
      try {
          getHtml();
      }
      catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
    }

    public void getHtml() throws ClientProtocolException, IOException {
        HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet("http://www.yahoo.com");
        HttpResponse response = httpClient.execute(httpGet, localContext);
        String result = "";

        BufferedReader reader = 
            new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        String line = null;
        while ((line = reader.readLine()) != null){
            result += line + "\n";
            // Toast.makeText(Connect.this, line.toString(), Toast.LENGTH_LONG).show();

        }
    }

解决方案

I think you are trying to download the HTML code in the UI Thread. Try to download it in the background, using AsynkTask

Edit. If you say that it works on Android 2.2 but it doesn't work on Android 4.0/3.0 I'm completely sure you are trying to download it in the UI thread. From Android 3.0, you can't do long process in the UI thread because you can block it. You must do the download in a different thread
PS. Sorry for my english.
