double colon in url is loading indefinitely in a Webview and is treated as valid URL

Issue

I have a android webview and when I load a url with double colon after http it is loading indefinitely.

url used

http:://example.com/

all my methods in WebViewClient is also not being called

• shouldOverrideUrlLoading
• onPageStarted
• onPageFinished
• onReceivedError

so I cannot determine if an error is encountered when loading.

I tried to check it the url is valid via this code but it is still treated as a valid URL

    public static boolean isValidUrl(String urlString) {
        boolean result = true;

        try {
            URL url = new URL(urlString);
            url.toURI();
        } catch (Exception e) {
            result = false;
        }

        return result;
    }

Is this expected in android webview?

Solution

Use the below code:

private boolean isURLCanBeLoadedToWebview(String urlString) {
   return Patterns.WEB_URL.matcher(urlString).matches();
}
