public class MainActivity extends Activity { 

EditText name;

Button btn; 
string resultat=null; 
InputStream is = null;

      post.setEntity(new UrlEncodedFormEntity(donnees)); 
      client.execute(post); 
      login.setText(""); 
      Toast.makeText(this, "valid login", Toast.LENGTH_SHORT).show();

我的建議是使用排這裏是一個非常小的樣品：

https://github.com/ogrebgr/android_volley_examples/blob/master/src/com/github/volley_examples/Act_SimpleRequest.java

一個Jar抽射。

但你可以嘗試這樣的Util：

public static class Connector extends AsyncTask<String, Object, Object> { 
    private static final int DEFAULT_CNN_TIME_OUT = 1000 * 20; 
    private static String USER_AGENT; 
    private String   mUrl; 
    private byte[]   mBody; 

    public Connector(Context _cxt) { 
     super(); 
     if(TextUtils.isEmpty(USER_AGENT)) { 
      // Without this, the default provided by API will be like "Dalvik/1.6.0 (Linux; U; Android 4.0.4; BASE_Lutea_3 Build/IMM76D)" . 
      USER_AGENT = new WebView(_cxt).getSettings().getUserAgentString(); 
     } 
    } 

    /* 
    * Convenient function to execute the connecting task. 
    */ 
    public void submit(String _url) { 
     this.execute(_url); 
    } 

    @Override 
    protected Object doInBackground(String... _params) { 
     mUrl = _params[0]; 
     Object ret = null; 
     HttpURLConnection conn = null; 
     try { 
      synchronized(Connector.class) { 
       InputStream in = null; 
       conn = connect(mUrl); 
       // if we don't do conn.setRequestProperty("Accept-Encoding", "gzip"), the wrapper GZIPInputStream can be removed. 
       onConnectorInputStream(in = new GZIPInputStream(conn.getInputStream())); 
       in.close(); 
       in = null; 
      } 
     } 
     catch(Exception _e) { 
      ret = _e; 
     } 
     finally { 
      if(conn != null) { 
       conn.disconnect(); 
       conn = null; 
      } 
     } 
     return ret; 
    } 

    @Override 
    protected void onPostExecute(Object _result) { 
     if(_result instanceof SocketTimeoutException) { 
      onConnectorConnectTimout(); 
     } else if(_result instanceof ConnectorPostConnectException) { 
      onConnectorError(((ConnectorPostConnectException) _result).getStatus()); 
     } else if(_result instanceof Exception) { 
      onConnectorInvalidConnect((Exception) _result); 
     } else if(_result == null) { 
      onConnectorFinished(); 
     } 
     handleEstablishedConnection(); 
    } 

    /* 
    * Internal help and test function. 
    */ 
    private static void handleEstablishedConnection() { 
     try { 
      Log.v(TAG, "Connection is established."); 
      CookieStore cs = CookieManager.getInstance().getCookieStore(); 
      if(cs != null) { 
       Log.v(TAG, "------------cookies------------");

     URL url = null; 
     HttpURLConnection conn = null; 
     try { 
      try {

    } 

    private HttpURLConnection postConnect(HttpURLConnection conn) throws Exception {

使用此UTIL：

mConn = new Util.Connector(getApplicationContext()) { 
      @Override 
      protected String onSetBody() { 
       String body = null; 
       try {

        bodyBuilder 
          .append("id=")//.append(...) 
          .append('&') 
          .append("mal=")//.append(...) 
        body = bodyBuilder.toString(); 
        bodyBuilder = null; 
       } 
       catch(Exception _e) { 
        Log.e(TAG, "Error in onCreateBody: " + _e.getMessage()); 
       } 
       finally { 
       } 
       return body; 
      } 



      @Override 
      protected int onSetConnectTimeout() { 
       return 10 * 1000; 
      } 

      @Override 
      protected void onConnectorInvalidConnect(Exception _e) { 
       super.onConnectorInvalidConnect(_e); 
       onErr(); 
      } 

      @Override 
      protected void onConnectorError(int _status) { 
       super.onConnectorError(_status); 
       onErr(); 
      } 

      protected void onConnectorConnectTimout() { 
       super.onConnectorConnectTimout(); 
       onErr(); 
      } 

      private void onErr() { 
       //mConn.submit(URL); 
      }; 

      @Override 
      protected void onConnectorFinished() { 

      } 

      @Override 
      protected void onConnectorInputStream(InputStream _in) { 

      } 
     }; 
     mConn.submit(URL);
