奇妙な問題に直面しています。3G サービス (プロキシあり) に切り替えるとアプリケーションだけが機能しませんが、WIFI と 3G (プロキシなし) ではうまく機能しています。

Starhub (ネットワーク プロバイダー) から提供されたデフォルトのプロキシとポート:

Proxy: 10.12.1.2
Port: 80

データについては、SOAP リクエストを Web サーバーに送信しています。

これが私のコードです：

public class SearchThread extends Thread {
private String mUrl;
private SoapSerializationEnvelope mEnvelop;
private Handler mHandler;
private String mSoapAction;
private KeepAliveHttpsTransportSE mTransport;

public SearchThread(String url) {
    this.mUrl = url;
}

@Override
public void run() {
    mEnvelop = new SoapSerializationEnvelope(SoapSerializationEnvelope.VER11);
    mEnvelop.setOutputSoapObject(interfaceListener.getSoapObject(element));
    mSoapAction = interfaceListener.getSoapAction(element);
    try {
        TrustManagerManipulator.allowAllSSL();
        mTransport = new KeepAliveHttpsTransportSE(URLS.URL_MAIN, 443, mUrl, 60000);
        mTransport.call(mSoapAction, mEnvelop);
        if (this.isInterrupted()) {
            Log.v(TAG,"Interrupted");
            return;
        }
        recevedSoapResponse(mEnvelop.getResponse());
    } catch (SocketException ex) {
        Log.e("Error : ", "Error on soapPrimitiveData() " + ex.getMessage());
        ex.printStackTrace();
    } catch (IOException e) {
        interfaceListener.recievedParsingResults(
                PARSER.RESULT.CONNECTION_FAILED, element, mHandler, mView);
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
        interfaceListener.recievedParsingResults(
                PARSER.RESULT.INTERNAL_ERROR, element, mHandler, mView);
    }
}
private void recevedSoapResponse(Object response) {
   //Parsing XML here.
}
public class KeepAliveHttpsTransportSE extends HttpsTransportSE
{
    private final String host;
    private final int port;
    private final String file;
    private final int timeout;
    private ServiceConnection serviceConnection;

    public KeepAliveHttpsTransportSE (String host, int port, String file, int timeout) {
        super(host, port, file, timeout);
        this.host = host;
        this.port = port;
        this.file = file;
        this.timeout = timeout;
    }
 //@Override
    public ServiceConnection getServiceConnection() throws IOException
    {
        if (serviceConnection == null) {
            serviceConnection = new HttpsServiceConnectionSE(host, port, file, timeout);
            serviceConnection.setRequestProperty("Connection", "keep-alive");
        }
        return serviceConnection;
    }
}

}

そして、ここに私のSSLコードがあります：

public class TrustManagerManipulator implements X509TrustManager {
    private static TrustManager[] trustManagers;
    private static final X509Certificate[] acceptedIssuers = new X509Certificate[] {};

public boolean isClientTrusted(X509Certificate[] chain) {
    return true;
}

public boolean isServerTrusted(X509Certificate[] chain) {
    return true;
}

public static void allowAllSSL() {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    });
    SSLContext context = null;
    if (trustManagers == null) {
        trustManagers = new TrustManager[] { new TrustManagerManipulator() };
    }
    try {
        context = SSLContext.getInstance("TLS");
        context.init(null, trustManagers, new SecureRandom());
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    HttpsURLConnection.setDefaultSSLSocketFactory(context
            .getSocketFactory());
}

public void checkClientTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
}

public void checkServerTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
}

public X509Certificate[] getAcceptedIssuers() {
    return acceptedIssuers;
}
}

例外：

追加情報: 他のすべてのアプリケーションは 3G ネットワーク (プロキシ設定あり/なし) で実行されており、私のアプリケーションでは SOAP リクエストのみが機能していません。

考えられるすべてのケースを試しましたが、うまくいきません。いくつか入力してください。

前もって感謝します。
