how to pass data from activity to webview with external website

I am making an app for tracking courier. the user will enter tracking no.in apps textview and click submit this will open couriers website tracking page i.e fedex in a webview inside the App.
Now i want a way to pass those tracking no from my app to webview's website input field and click the submit button on the website automatically

I don't think this the way you should do that, you should look for a url that takes the tracking location number as a query and return the proper page
something like that http://example.com/over/there?number=441222
Update
I've looked at the page you've mentioned in the comments and all I can get is that it submits a post request as a form input
POST url: https://www.myutiitsl.com/PAN_ONLINE/PANTrackerSearch.action
parameter names are
appNo
panNo
I wish I had more knowledge as a web developer but this the way that could work with you try to make sure the post url is correct and the parameters I mentioned also correct and it should work with you

Call HTML page with javascript content

I am stuck at an issue, I don't know if its possible or not.
I need to call a HTML page, but the page has some content being loaded via Javascript too and I need to get that also.
Is this some how possible ?
Currently I have used plain: new URL(url).openConnection() and it's not returning that.
Any Help ?
Thanks

To do that you'll need to host a WebView in your application. It can be hidden if you want. Call the webview loadUrl to load the content you want. Handle the WebViewClient onPageFinished so you know all of the content has loaded, and then use the javascript bridge interface (addJavascriptInterface) to pass the HTML back up to the application.

Android, YUI, Moodle

The problem I'm having is the following:
I have an app with two separate modes: A WebView for browsing and a custom Canvas. The custom Canvas captures handwriting samples for language placement exams. Here's how it works. A user logs in to Moodle via the WebView. After they log in, they navigate to a Quiz inside Moodle. They click a link on one of the Quiz's questions and this launches an Intent which hides the WebView and shows the Canvas. The user then writes (using a stylus) on the Canvas. When a user is finished writing their essay (or whatever), they press a button that uploads an image file to Moodle. I am able to upload images to a point, it's getting them to show up in the HTML page that the user clicked the link in originally (see above) and to get Moodle to commit them to permanent storage that is the problem. Normally this is all accomplished through AJAX (really AJAJ since it's JavaScript and JSON) and when the user drops a file on this one component, the component refreshes and uploads the file.
Here is the problem: I need the WebView so that students can log in to Moodle through Shibboleth. But because the underlying JavaScript in the browser makes AJAX calls to the Moodle server and since the Java side of Android doesn't have access to the DOM, I have use the Apache HTTP components library to make some of the connections below basically to preserve the state of the HTML page in WebView.
In a desktop browser on, say, Windows, I use WebScarab to monitor the browser's requests and this is what I see: the browser uploads a file to Moodle via five successive calls to the following scripts:
POST https://[moodle website]/repository/repository_ajax.php [posts multipart form data]
POST https://[moodle website]/repository/draftfiles_ajax.php [posts some params]
GET https://[moodle website]/draftfile.php/[some_id]/user/draft/[some_id]/[somefilename.png] [returns an icon of the image for a filepicker from YUI]
POST https://[moodle website]/mod/quiz/processattempt.php [returns HTML page]
GET https://[moodle website]/mod/quiz/summary.php [returns HTML page]
Some of these scripts return, as you'd expect, JSON data since they're AJAX and not HTML. The final two calls (4 & 5) return HTML. Now, I can make all of those calls in succession in either the WebView or the Apache HTTP library, but if I do so with WebView, only JSON data is returned to the WebView in calls 1-3 (WebView treats the JSON data as a page and displays it wiping out whatever HTML page was displayed in it). If I capture and process the JSON data using the Apache HTTP library in Java, then the JavaScript components internal to the page do not get updated. If I split the calls so that I send only calls 4 & 5 to the WebView, the HTML merely returns WebView to the first question of the exam and Moodle acts as if I haven't uploaded anything.
I can verify that files are uploading if I manually refresh (press a link) the JavaScript UI elements in the page. I can't expect students to do this, though, because the link to do so is very tiny and it's not obvious that it does a refresh. I need a way to programmatically refresh this one element (it's part of YUI) or to get Android and the Java side to play more nicely with the JavaScript/DOM side.
My question is: does anyone know a way to 1) fire off a drag and drop event using YUI to an element inside an HTML page or 2) a way to consume the JSON data and pass it to an element inside the HTML page.
I'm banging my head against a wall trying to figure this out.
OK, so I figured out that: javascript:document.getElementsByClassName(\"[name of link here]\")[0].click() works in Chrome on the desktop but doesn't work if I pass it to WebView.loadURL(). I just need to be able to simulate that click event reliably in WebView. It appears not to support click(). Anyone have any ideas?

The winning code is:
el = document.getElementsByClassName("[some element]")[0];
var event = document.createEvent("MouseEvents");
event.initEvent("click", true, true);
el.dispatchEvent(event);
This selects the link at [some element] and thereby fires an AJAX request that refreshes the FilePicker. For those working with Moodle, I had to add the above code to the same quiz question that handles so it is invoked by putting that code in its own function and calling it with WebView.loadURL("javascript:myRefreshFunction()").

autologging into a website

I want to login into a website. I need to identify the url to login. The view source shows post method as follows.
<form id="signIn" onsubmit="return false;" action="/f1/logon" method="post">
I see that there is no javascript that validates the url.
When i use the below url directly on a browser,
https://www.abc.com/f1/logon
I get a blank page. When I use below,
https://www.abc.com/logon
I dont see the repsonse of the loggedin page. It shows the response of the signin page though. How do i identify the correct url to autologin. downloaded soem toold like fiddler but no help. any inputs?

Invoking a URL in a browser sends a GET request. This form, however, is configured to send a POST request (look at the method attribute), so it makes sense that you are not seeing anything in your browser.
It's strange that the onsubmit attribute returns false. This prevents the form from being submitted at all. Take a look at the "login" button. There may be some Javascript code there which does the form submission.

Fidller is a good tool, you can start capture job and then you perform a login. Find which request contain your login and password.

changing URL via AJAX using wicket

Is there a way to make an AJAX call alter the current page URL without redirecting or reloading the page, in Apache Wicket?
For example, say we are in the url:
localhost:8080/someUrl
I'd like that when I click an ajax link, some action is performed, and the url changes to, say:
localhost:8080/otherUrl
without redirecting, just changing the url displayed in the browser.
Is this even possible?
Thanks!
Manuel

Actually you can !
But this is not related to Wicket at all.
This is what the new History API in HTML5 is about.
Just search for "html5 History API example" in Google and enjoy.

The only part of the url you can change with javascript is the hash
You could change localhost:8080/#/someUrl to localhost:8080/#/otherUrl
Do this with window.location.hash
Here's an example of a flash site which uses this concept to allow for deep-linking URL's: http://www.2advanced.com

Help make this feature happen, vote (or contribute!) for https://issues.apache.org/jira/browse/WICKET-5290

No, it isn't. If you change the location in the browser, a new request is made to that URL.
(You do that with window.location.href = newUrl, but the page reloads)
