title: PayU Payment Integration in Android Issue
body: <p>I am trying to integrate <code>Payment Gateway (PayU)</code> in Android through <code>WebView</code>.
  I am able to send the data to the <code>PayU</code> through POST.
  After successful transaction, the page is not redirecting to the "surl" i.e successUrl / "furl" i.e FailureUrl. It always shows page not found.</p>
  
  <p>Following is the code of <code>WebView</code>:</p>
  
  <pre><code>webView = (WebView) findViewById(R.id.webview1);
  String postData = "Required Data sent to PayU by POST";
  webView.setWebViewClient(new WebViewClient(){
      @Override
      public void onPageStarted(WebView view, String url, Bitmap favicon) {
           Log.d("Page_Started",url);
      }
  
      @Override
      public void onPageFinished(WebView view, String url) {
           Log.d("Page_Finished",url);
      }
  });
  
  webView.getSettings().setUserAgentString("Mozilla/5.0 (Linux; U; Android 2.0; en-us; Droid Build/ESD20) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17");
  webView.getSettings().setDomStorageEnabled(true);
  webView.getSettings().setJavaScriptEnabled(true);
  webView.getSettings().setSupportMultipleWindows(true);
  webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
  webView.getSettings().setSupportZoom(true);       //Zoom Control on web (You don't need this
  //if ROM supports Multi-Touch
  webView.getSettings().setBuiltInZoomControls(true);
  webView.postUrl(action, EncodingUtils.getBytes(postData, "BASE64"));
  </code></pre>
  
  <p>In Log, its not showing any success url / failure url. I always get a message from <code>PayU</code> that <code>Page Not Found-404</code></p>
  
  <p>Do I have to make some changes in webView?
  Its working perfect in <code>WebPage</code>, not working in Android.</p>
