Fix WebView Update Issues in Android Apps

To address the issue of WebView not updating, you can try the following methods:

1. Clearing cache: When loading a webpage in WebView, some data may be cached which prevents the page from updating. You can try clearing WebView’s cache by using the following code:

webview.clearCache(true);
webview.clearHistory();

2. Set caching mode: You can configure the caching mode of the WebView to not use any cache by using the following code.

webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

3. Force refresh: You can try using the reload() method of WebView to force a refresh, you can call it with the following code:

webview.reload();

4. Update WebView version: If you are using an older version of WebView, there may be some bugs or problems. You can try updating the WebView version using the following code.

WebView myWebView = (WebView) findViewById(R.id.webview);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    myWebView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}

Sometimes simply restarting the application or device can solve the WebView update issue.

If the above methods still can’t solve the problem, it may be necessary to further investigate the specific reasons. This can be done by checking the error logs of the WebView, inspecting the network connection, and so on.
