java - 无效使用 SingleClientConnManager : connection still allocated

Question

我想知道为什么这段代码不执行？我正在尝试通过 POST 方法从我的设备发送数据，但没有错误。该应用程序通过传达“我的应用程序已停止。”在我的设备上自行完成:

这里是执行:

KlientNameValue kn = new KlientNameValue(getApplicationContext());
kn.new  MyAsyncTask().execute(zam.klient.getNazwa(),zam.klient.getNip(),zam.klient.getAdres());

这里是代码:

public class KlientNameValue {

List<NameValuePair> KlientNameValuePairs = new ArrayList<NameValuePair>();
Context context;
public KlientNameValue(Context context) {
    super();
    this.context=context;
}



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

      @Override protected Void doInBackground(String... params) { 
          // TODO     Auto-generated method stub 
          postData(params[0], params[1], params[2]);
      return null;

      }

      @Override
      protected void onPostExecute(Void result) {

      Toast.makeText(context , "Zlecenie zostało wysłane",
     Toast.LENGTH_LONG).show();
          }

      void postData(String nazwa, String nip, String adres) {
          HttpClient httpclient = new DefaultHttpClient();
          HttpPost httppost = new HttpPost("here is my default link :)");

      try { // Add your data

      KlientNameValuePairs = new ArrayList<NameValuePair>();
      KlientNameValuePairs.add(new BasicNameValuePair("Kli_imie", nazwa));
      KlientNameValuePairs.add(new BasicNameValuePair("Kli_adres", adres));
      KlientNameValuePairs.add(new BasicNameValuePair( "Kli_nr_telefonu",
      nip)); 



      httppost.setEntity(new UrlEncodedFormEntity( KlientNameValuePairs));
      HttpResponse response = httpclient.execute(httppost);
      //httppost.setEntity(new UrlEncodedFormEntity( 
      //      ZamowienieNameValuePairs)); // HttpResponse response1 =



      } catch (IOException e) { // TODO Auto-generated catch block
      e.printStackTrace(); }

      }

      }

错误:

02-15 17:45:24.695: E/AndroidRuntime(21890): at android.widget.Toast.<init>(Toast.java:94) 
02-15 17:47:19.343: W/SingleClientConnManager(22288): Invalid use of SingleClientConnManager: connection still allocated.
 02-15 17:47:19.343: W/SingleClientConnManager(22288): Make sure to release the connection before allocating another one. 

Answer 1

Invalid use of SingleClientConnManager: connection still allocated.

你在消费它之前执行了两次完全错误的http请求。所以删除第二个 httpclient.execute(httppost); 因为你已经执行了这个 http 请求。

然后调用它

httpResponse.getEntity().consumeContent();

Above method is called to indicate that the content of this entity is no longer required. All entity implementations are expected to release all allocated resources as a result of this method invocation
