在WIFI和3G上工作的Android應用（沒有代理），但沒有在3G上工作（如果分配了代理和端口）

Question

我面臨一些奇怪的問題，只有我的應用程序在切換到3G服務時不工作（使用代理），但它在WIFI和3G（沒有代理）方面效果很好。我的星和（網絡運營商）給出

默認代理和端口：

Proxy: 10.12.1.2 
Port: 80 

對於數據，我發送SOAP請求我的網絡服務器。

這裏是我的代碼：

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; 
    } 
} 

}

這裏是我的SSL代碼：

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：所有其他應用程序正在運行3 G網絡（有/無代理設置）和在我的應用程序中，只有SOAP請求不起作用。

我試過所有可能的情況，但沒有運氣。請給我提供一些意見。

在此先感謝。

也許你已經太晚了四次，但我希望這會有助於未來的人們像我一樣到達這裏，在同樣的問題上變得瘋狂。

這是一個Android bug。一切工作正常與WiFi，但它在3G上崩潰。它發生在4.1上，但在4.2.2上沒有問題。

爲了解決它，你必須修改文件org.ksoap2.transport.HttpTransportSE（我已經擴展了新的一個並把它稱爲MyHttpTransportSE因爲我使用kso​​ap2組裝罐子）。 只需重寫方法公共無效調用（字符串的soapAction，信封的SoapEnvelope）註釋掉行

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

當然，如果你使用SSL的工作，你需要從擴大自己HttpsTransportSE你的新的MyHttpTransportSE。
