Android应用程序在WIFI和3G(无代理)上运行,但不在3G上运行(如果分配了代理和端口)

我面临一些奇怪的问题,当我切换到3G服务(使用代理)时,只有我的应用程序无法工作,但它在WIFI和3G(没有代理)方面工作得很好.

我的Starhub(网络提供商)提供的默认代理和端口：

Proxy: 10.12.1.2
Port: 80

对于数据,我正在向我的网络服务器发送肥皂请求.

这是我的代码：

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,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,timeout);
            serviceConnection.setRequestProperty("Connection","keep-alive");
        }
        return serviceConnection;
    }
}

}

这是我的SSL代码：

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;
}
}

附加信息：所有其他应用程序都在3G网络上运行(有/无代理设置),在我的应用程序中,只有SOAP请求不起作用.

我已经尝试了所有可能的情况,但没有运气.请给我一些意见.

提前致谢.

解决方法

也许你已经太晚了,但我希望这会有助于未来的人像我一样到达这里,对同样的问题变得疯狂.

这是一个Android错误.一切都适用于WiFi,但它在3G上崩溃.它发生在4.1上,但在4.2.2上没有问题.

要解决它,你必须修改文件org.ksoap2.transport.HttpTransportSE(我已经扩展了一个新文件,并将其命名为MyHttpTransportSE,因为我使用的是ksoap2程序集jar).
只需覆盖方法public void call(String soapAction,SoapEnvelope envelope)注释掉该行

//connection.setRequestProperty("Connection","close");

当然,如果您正在使用SSL,则需要从新的MyHttpTransportSE扩展自己的HttpsTransportSE.
