當我嘗試發送帖子請求時，我的應用崩潰了android

Question

public class HttpHandle extends AsyncTask<String, Void, Void> { 

List<NameValuePair> parm; 
HttpClient client; 
HttpPost post; 
String responseBody; 
HttpResponse response; 
XMLParser parser; 
org.w3c.dom.Document doc; 

public HttpHandle(String url,int full) { 
    client = new DefaultHttpClient(); 
    post = new HttpPost(url); 
    parm = new ArrayList<NameValuePair>(full); 
    this.responseBody = ""; 
} 

public void addInfo(String key, String value) 
{ 
    parm.add(new BasicNameValuePair(key, value)); 
} 

public String getRes() 
{ 
    return this.responseBody; 
} 

@Override 
protected Void doInBackground(String... params) { 
    // TODO Auto-generated method stub 
    try { 
     post.setEntity(new UrlEncodedFormEntity(parm,HTTP.UTF_8)); 
     response = client.execute(post); 
     this.responseBody = EntityUtils.toString(response.getEntity()); 
    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    return null; 
} 

protected void onPostExecute() { 
// Call onRefreshComplete when the list has been refreshed. 
    super.onPostExecute(null); 
} 
} 

我正在使用此類從我的應用發送帖子請求，但是當我嘗試在手機上運行它時，應用崩潰。

這是我用我的登錄活動代碼：

String user = username.getText().toString(); 
       String pass = password.getText().toString(); 


       HttpHandle handle = new HttpHandle("url",2); 
       handle.addInfo("username", user); 
       handle.addInfo("password", pass); 
       String responseBody = handle.execute(); 

我發現了很多解決方案，但我沒有成功，使其工作。 日誌錯誤：

02-08 19:58:00.252: D/before(4048): From HERE 02-08 19:58:00.262: D/libc(4048): [NET] getaddrinfo hostname www.raffle.coder.co.il, servname NULL, ai_family 0 02-08 19:58:00.272: D/libc(4048): [NET] getaddrinfo hostname www.raffle.coder.co.il, servname NULL, ai_family 0 02-08 19:58:00.272: I/global(4048): call createSocket() return a new socket. 02-08 19:58:00.272: D/libc(4048): [NET] getaddrinfo hostname 80.179.219.93, servname NULL, ai_family 0

現在，當我試着點擊「登錄」按鈕沒有happneds。

您不應該重新實現​​方法，這可能與崩潰有關。但是，回溯記錄有助於澄清。
