can also be used to indicate that an application should
not cache particular content.
Devices running platforms older than Android 4.4 (API level 19) +use a version of {@link android.webkit webkit} that has a number of security issues. +As a workaround, if your app is running on these devices, it +should confirm that {@link android.webkit.WebView} objects display only trusted +content. You should also use the updatable security {@link +java.security.Provider Provider} object to make sure your app isn’t exposed to +potential vulnerabilities in SSL, as described in Updating Your +Security Provider to Protect Against SSL Exploits. If your application must +render content from the open web, consider providing your own renderer so +you can keep it up to date with the latest security patches.
