You can use setWebViewClient method of webview and then implement a new webViewClient, then you can access full url by using onPageFinished method. see code below.

webView.setWebViewClient(new WebViewClient()
{

    @Override
    public void onPageFinished(WebView view, String url)
    {
        if (url.contains("#access_token=")) //I am looking for #access_token= hash, you can look for any parameter here
        {
            String accessToken = url.substring(url.indexOf("#access_token=") + 14, url.length()); //14 is my "#access_token=" length, yours will be different
            writeAccessTokenToFile(accessToken); //this method is your method
            loadApplication(); //then load you application logic, this is your method too
        }
    }
});
