How can the opening of installed apps by clicking on a link be prevented in Webview?

edit

One way to prevent the opening of installed apps by clicking on a link in Webview is to disable the deep linking feature. This can be done by implementing a custom WebViewClient and overriding the shouldOverrideUrlLoading method.

Here is an example code snippet to disable deep linking:

webView.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // Check if the URL is a deep link
        if (url.startsWith("intent://") || url.startsWith("market://")) {
            // Return true to prevent the app from opening the link
            return true;
        } else {
            // Return false to allow the link to be opened normally in the WebView
            return false;
        }
    }
});

In the above example, we check if the URL is a deep link (starting with "intent://" or "market://"). If it is, we return true to prevent the app from opening the link. If it's a regular link, we return false to allow it to be opened normally in the WebView.
