Buggy source:
@Override public boolean shouldOverrideUrlLoading(WebView view,String stringUrl){
  try {
    final Uri url=Uri.parse(stringUrl);
    final String loadedHost=url.getHost();
    if (loadedHost == null) {
      return false;
    }
    final String loadedPath=url.getPath();
    final String currentSiteHost=Uri.parse(mSiteModel.getUrl()).getHost();
    if (loadedHost.equals(currentSiteHost) && loadedPath != null && loadedPath.contains(LOGIN_PATH) && stringUrl.contains(REDIRECT_PARAMETER)) {
      redirectPage=extractRedirect(stringUrl);
      loginToWPCom(view,mSiteModel);
      return true;
    }

    if (loadedHost.equals(currentSiteHost) && loadedPath != null && loadedPath.contains(LOGIN_PATH) && stringUrl.contains(REDIRECT_PARAMETER)) {
