如何在WebView中禁用本地存储和会话存储

Question

我想在Android的webView中禁用本地存储和会话存储。我已经尝试了下一个配置：

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setGeolocationEnabled(true);
    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    webSettings.setDomStorageEnabled(false);
    webSettings.setDatabasePath(null);
    webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
    webSettings.setAppCacheEnabled(false);
    webSettings.setAppCachePath(null);
    webSettings.setLoadWithOverviewMode(true);
    webSettings.setUseWideViewPort(true);
    webSettings.setBuiltInZoomControls(true);

    webSettings.setSaveFormData(false);
    webSettings.setSavePassword(false);
    webSettings.setDomStorageEnabled(false);

但是它仍在生成可能不安全的相关信息。有人遇到过这个问题吗？
