Ignore a file url from android webview caching

I want to Android webview cache my website. But I don't want to cache a js file that maybe update every 5 minutes. Is it possible to ignore this file from android webview caching?

Solution

  • No, one can only set caching completely to false:

    mWebView.getSettings().setAppCacheEnabled(false);
mWebView.clearCache(true);

    You could ignore caching to that specific js file by using a timestamp as a request parameter when loading that file.

    For example, you could include your js file like this:

    <script src="js/my_script.js?ver=1626534617"></script>

    (where 1626534617 is the current Unix timestamp)

    Using a parameter like that, will result in always requesting for the file from the server, hence bypassing the webview cache.
