How to fetch the values present in a url from a webview in android?

Question

I have a url where there are ids (such as order id, product id, etc) in a webview. How can I fetch these ids and put them into strings? Say for example, the url is

www.xyz.com/buy/thankyou/handlers/display.html?ie=UTF8&asins=B00F0G8K&orderId=404-35644-70307&purchaseId=404-2849-9658

I need the values present for &asins, &orderid, &purchase_id and pass them to another url. How can I fetch them? All of this is happening inside a webview.

Use `webView.getUrl()` and then a regex to extract the values. — Jonas Czech, Apr 11 '15 at 10:26

Get the URL from WebView, parse it as Uri and get individual query parameters from it.

Example:

Uri uri=Uri.parse(myWebView.getUrl());
String orderId = uri.getQueryParameter("orderid");

should i put this inside shouldOverrideUrlLoading()? – arv Apr 15 '15 at 14:17
No, use this anytime you want to read the current URL of WebView. Just make sure that the URL is loaded. – Rax Apr 15 '15 at 14:53
best answer, simple and direct. – Eman Mar 17 '22 at 21:02

Just saw the answer by @rax, it is probably better.

Try something like this:

String regex = "asins=(.*)&orderId=(.*)&purchaseId=(.*)";
String myString = "www.xyz.com/buy/thankyou/handlers/display.html?ie=UTF8&asins=B00F0G8K&orderId=404-35644-70307&purchaseId=404-2849-9658 ";
//use String myString = webView.getUrl(); in your case;
Pattern pattern = Pattern.compile(regex); 
Matcher matcher = pattern.matcher(myString);

while (matcher.find()) {
        System.out.println(matcher.group().replaceAll(regex, "$1"));
        System.out.println(matcher.group().replaceAll(regex, "$2"));
        System.out.println(matcher.group().replaceAll(regex, "$3"));
    }

Output:

B00F0G8K
404-35644-70307
404-2849-9658

Hope this helps, and do comment if you have any questions.

One more doubt Jonas, How to get multiple ids? ie, if there are multiple orderids, how to fetch it? Also, How to reload the ids to another URL? – arv Apr 14 '15 at 13:54
@arv, In that case, try the answer by rax, or update your question with an example of a URL string you want to get the order ids from, and I will update my answer. – Jonas Czech Apr 14 '15 at 13:56
Okay, Consider the url in the above question as 1st url. The 2nd url is : http://sndbx.abc.com/mob#?path=confirmOrder&oid= &pid= &asins= . Here the values of the orderid(multiple) from the first url should be filled here in the 2nd url ie, 2nd url should be http://sndbx.abc.com/mob#?path=confirmOrder&oid=404-35644-70307&pid=404-2849-9658 &asins=B00F0G8K – arv Apr 15 '15 at 05:55
@arv, I will have a look. – Jonas Czech Apr 15 '15 at 06:33
@arv, will probably be a few hours, as i have other stuff to do. – Jonas Czech Apr 15 '15 at 07:58
@arv, sorry for taking so long, as i'm _very_ busy today, did you try the answer by rax ? Otherwise, you can do it with a separate regex. If you want an answer faster, ask a new question, and tag it with "regex". – Jonas Czech Apr 15 '15 at 12:41
oh :( I tried it, but i'm not getting the ids. Its not working. I checked it with LogCat. – arv Apr 15 '15 at 13:08
@arv, Could you edit some example url's into your question, as the comment system seems to have mangled the one you posted. – Jonas Czech Apr 15 '15 at 18:13
@arv, you could also use `String.split()`, as per [here](http://stackoverflow.com/a/13691481/4428462). – Jonas Czech Apr 15 '15 at 21:23
Ya okay.. Got it Jonas. Thanks ! I used rax's answer. – arv Apr 16 '15 at 06:28
How to reload the 2nd url in the webview? – arv Apr 16 '15 at 06:43
@arv, you can use `webview.reload()` – Jonas Czech Apr 16 '15 at 06:59
