Shouldoverrideurlloading in Webview for Android Not Running

shouldOverrideUrlLoading in WebView for Android not running

After some research I conclude that despite what most of the tutorials out there say, shouldOverrideUrlLoading() does not get called when:

1. You load a URL like

   loadUrl("http://www.google.com");
   

2. The browser redirects the user automatically via an HTTP Redirect. (See the comment from @hmac below regarding redirects)

It does however, get called when you you click on a link inside a webpage inside the webview. IIRC the twitter authorization uses an HTTP Redirect.. Bummer, this would be helpful if it worked how all the tutorials say it does. I think this is from a very old version the Android API...

You might want to consider overriding the onProgressChanged method of a WebChromeClient like here: How to listen for a WebView finishing loading a URL? or the onPageFinished() method of the WebViewClient.

webview shouldOverrideUrlLoading not working

return true; instead

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);

    return true;
}

WebView shouldOverrideUrlLoading() not called for invalid links

You're probably using the KitKat WebView. This is a known issue (I think it's outlined in the migration guide) where URLs that can't be resolved against the base URL are dropped on the floor (you won't get any callbacks for them, neither shouldOverrideUrlLoading nor onPageStarted).

The problem is that your base URL is a data url, so you're trying to resolve '/q?type=short' against 'data:text/html,...' which doesn't make much sense and so the whole attempt to navigate to the URL gets ignored.

This was different for the pre-KK WebView which used KURL instead of GURL for URL processing. GURL is generally more strict (and more secure) than KURL, which is the cause for some incompatibility between the two WebView versions.
