    setContentView(R.layout.activity_main);

    WebView webv = (WebView)findViewById(R.id.MainActivity_webview);         
    webv.setWebViewClient(newWebViewClient(){
            @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                returntrue;
            }
    });

    String postData = FIELD_NAME_LOGIN + "=" + LOGIN +
            "&" + FIELD_NAME_PASSWD + "=" + PASSWD;

    // this line logs you in and you stay logged in// I suppose it works this way because in this case WebView handles cookies itself
    webv.postUrl(URL, EncodingUtils.getBytes(postData, "utf-8"));
}
