Problem Solved. in webview onCreate
i have to call url. like this web = callURL();
and to load url use loadDatawithBaseUrl. after that you have to make a public class callURL(){
. set the proxy in there. like this
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpHost proxy = new HttpHost("your host", your proxy); //proxy that i need
httpClient.getParams().setParameter(ConnRouteParams.DEFAULT_PROXY, proxy);
httpClient.getCredentialsProvider().setCredentials(
new AuthScope("your host", your proxy),
new UsernamePasswordCredentials(
"your username", "your password"));
and then in httpget. call your url too. thats it. good luck
