Android 获取在编辑文本中输入的URL的源

我有一个要求，在那里我必须得到的URL地址是在编辑文本中输入的来源。我能够获取在HTTPGET请求中硬编码的URL的源文件。代码如下

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


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

    String line = null;
    while ((line = reader.readLine()) != null){
      result += line + "\n"; 
    Log.d("result","="+result);

    }

    return result;

}

并将其保存在文件中，如下所示：

 public void onClick(View v) {
            File file = new File(etPath.getText().toString());
            FileWriter writer=null;
            try
            {
                writer = new FileWriter(file);

                /** Saving the contents to the file*/
                writer.write(getHtml());

                /** Closing the writer object */
                writer.close();


                /** Getting sharedpreferences object to store the path of last saved file */
                SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();

                /** Setting the last saved file's path in the shared preference */
                editor.putString("fpath", file.getPath());

                /** Save the path to the shared preference */
                editor.commit();

                Toast.makeText(getBaseContext(), "Successfully saved", Toast.LENGTH_SHORT).show();

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    };

此方法正确地返回了google.com的源代码。 但我需要这样做：

HttpGet httpGet = new  HttpGet(etContent.getText().toString());

其中etContent是输入URL的编辑文本。 但当我执行这个语句时，它崩溃了

我需要提取编辑文本中输入的URL的源。我不打算使用异步任务。请帮帮我，伙计们

请发布一些支持代码。谢谢

我自己解决了这个问题。问题是我在输入URL时没有附加http://地址。现在工作正常了。谢谢大家：-）
