本文介绍了在android系统4.4+之间的HttpClient和web视图问题分享会的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我分享HTTP客户端和网络之间的会话查看它工作正常，我的是Android 4.1或更早的版本，但它不是在4.4或以上版本的工作吗？我不能够找出reason.any帮助将大大AP preciated
我的code是
公共类的AppSettings扩展应用
{
私有静态最终DefaultHttpClient客户端= createClient（）; @覆盖
公共无效的onCreate（）
{
} 公共静态DefaultHttpClient getClient（）
{
返回客户端;
} 私有静态DefaultHttpClient createClient（）
{
BasicHttpParams PARAMS =新BasicHttpParams（）;
SchemeRegistry schemeRegistry =新SchemeRegistry（）;
schemeRegistry.register（新计划（HTTP，PlainSocketFactory.getSocketFactory（），80））;
最终的SSLSocketFactory的SSLSocketFactory = SSLSocketFactory.getSocketFactory（）;
schemeRegistry.register（新计划（https开头，SSLSocketFactory的，443））;
ClientConnectionManager厘米=新ThreadSafeClientConnManager（参数，可以schemeRegistry）;
DefaultHttpClient的HttpClient =新DefaultHttpClient（厘米，则params）;
httpclient.getCookieStore（）的getCookies（）。
返回HttpClient的;
}
}
虽然做的http请求我使用下面code
尝试
{ DefaultHttpClient mClient = AppSettings.getClient（）;
HttpPost httppost =新HttpPost（URL）; httppost.setEntity（新UrlEn codedFormEntity（的NameValuePair））; //httppost.setEntity(responseBody）; HTT presponse响应= mClient.execute（httppost）; 如果（响应！= NULL）
{
responseBody = EntityUtils.toString（response.getEntity（））; }
其他
{
CustomLogger.showLog（测试版，响应为空）;
} } 赶上（例外五）
{
CustomLogger.showLog（测试版，异常在发送数据）;
e.printStackTrace（）;
}
为了与web视图我使用下列共享code
webView.setWebViewClient（新WebViewClient（）
{ @覆盖
公共无效onPageStarted（的WebView视图，字符串URL，位图图标）
{
super.onPageStarted（查看，网址，NULL）;
CustomLogger.showLog（测试版，页当前已启动的网址为+网址）;
webView.setVisibility（View.GONE）;
progress_loader.setVisibility（View.VISIBLE）;
DefaultHttpClient mClient = AppSettings.getClient（）;
饼干sessionInfo;
清单＆LT; Cookie和GT;饼干= mClient.getCookieStore（）的getCookies（）。
如果（！cookies.isEmpty（））
{
CookieSyncManager.createInstance（getActivity（））;
CookieManager cookieManager = CookieManager.getInstance（）; 对于（饼干饼干：饼干）
{
sessionInfo =饼干;
串cookieString = sessionInfo.getName（）+=+ sessionInfo.getValue（）
+;域=+ sessionInfo.getDomain（）;
CustomLogger.showLog（测试版，cookie字符串为+ cookieString）;
cookieManager.setCookie（http://www.example.com，cookieString）;
CookieSyncManager.getInstance（）同步（）。
}
}
其他
{
CustomLogger.showLog（测试版，无曲奇）; }
}
}
解决方案
我已经解决了我的问题。 Web视图OnPageStarted事件获取调用两次，我被检索的cookie，请参阅本链接。随着简单的计数器，我仅限于第一次，现在它工作正常。
cookie的检索I sharing session between http client and web view it works fine for me in android 4.1 or earlier versions but its not working in 4.4 or above versions? i am not able to figure out the reason.any help will be greatly appreciated My code is
public class AppSettings extends Application
{
private static final DefaultHttpClient client = createClient();
@Override
public void onCreate()
{
}
public static DefaultHttpClient getClient()
{
return client;
}
private static DefaultHttpClient createClient()
{
BasicHttpParams params = new BasicHttpParams();
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
final SSLSocketFactory sslSocketFactory = SSLSocketFactory.getSocketFactory();
schemeRegistry.register(new Scheme("https", sslSocketFactory, 443));
ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry);
DefaultHttpClient httpclient = new DefaultHttpClient(cm, params);
httpclient.getCookieStore().getCookies();
return httpclient;
}
}
While making http request i am using below code
try
{
DefaultHttpClient mClient = AppSettings.getClient();
HttpPost httppost = new HttpPost(url);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePair));
//httppost.setEntity(responseBody);
HttpResponse response = mClient.execute(httppost);
if (response != null)
{
responseBody = EntityUtils.toString(response.getEntity());
}
else
{
CustomLogger.showLog("Beta", "Response is null");
}
}
catch (Exception e)
{
CustomLogger.showLog("Beta", "Exception in Sending data");
e.printStackTrace();
}
in order to share it with webView i am using following code
webView.setWebViewClient(new WebViewClient()
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
super.onPageStarted(view, url, null);
CustomLogger.showLog("Beta", "onPage Started url is" + url);
webView.setVisibility(View.GONE);
progress_loader.setVisibility(View.VISIBLE);
DefaultHttpClient mClient = AppSettings.getClient();
Cookie sessionInfo;
List<Cookie> cookies = mClient.getCookieStore().getCookies();
if (!cookies.isEmpty())
{
CookieSyncManager.createInstance(getActivity());
CookieManager cookieManager = CookieManager.getInstance();
for (Cookie cookie : cookies)
{
sessionInfo = cookie;
String cookieString = sessionInfo.getName() + "=" + sessionInfo.getValue()
+ "; domain=" + sessionInfo.getDomain();
CustomLogger.showLog("Beta", "cookie string is " + cookieString);
cookieManager.setCookie("http://www.example.com", cookieString);
CookieSyncManager.getInstance().sync();
}
}
else
{
CustomLogger.showLog("Beta", "No cookies");
}
}
}
解决方案
I have solved my problem. OnPageStarted event of web view was getting called twice in which i was retrieving cookies,refer this link.With simple counter ,i restricted the retrieval of cookie only on first occasion and now its working fine
