monitor web browser programmatically in Android? -

i've got tricky question here. need users make payment bank (namely barclaycard) in uk. so, have https url , add parameters (such amount pay, order reference, etc) url, start http connection intent.actionview, redirect user browser can enter credit card details on bank's webpage , make payment our account successfully. far ?

the code use below (i changed values privacy reasons) problem is, need app when user has completed/failed/cancelled payment. barclaycardautomatically redirects particular url when payment has succeeded, 1 if failed. there no way of knowing when barclaycard payment has succeeded go android app somehow ?

button cardbutton = (button) findviewbyid(r.id.card_button); cardbutton.setonclicklistener(new view.onclicklistener() {     @override     public void onclick(view arg0)     {         string prehashstring = new string();         string prohashstring = new string();         string shapassphrase = new string();          shapassphrase = "gsvth£h70zkhdaq9b"; // test environment          prehashstring = prehashstring + "amount=" + string.valueof((int) (order.getpaymentamount() * 100.00)) + shapassphrase;         prehashstring = prehashstring + "bgcolor=cccccc" + shapassphrase;         prehashstring = prehashstring + "cn=" + user.getstring("name") + shapassphrase;         prehashstring = prehashstring + "currency=gbp" + shapassphrase;         prehashstring = prehashstring + "language=en_us" + shapassphrase;         prehashstring = prehashstring + "orderid=" + order.getorderid() + shapassphrase;          try         {             prohashstring = sha1(prehashstring);         }         catch (nosuchalgorithmexception e)         {             e.printstacktrace();         }         catch (unsupportedencodingexception e)         {             e.printstacktrace();         }          string redirecturl = "https://mdepayments.epdq.co.uk/ncol/test/orderstandard.asp";          redirecturl += "?amount=" + string.valueof((int) (order.getpaymentamount() * 100));         redirecturl += "&cn=" + user.getstring("name");         redirecturl += "&currency=gbp";         redirecturl += "&language=en_us";         redirecturl += "&orderid=" + order.getorderid();         redirecturl += "&shasign=" + prohashstring;          intent = new intent(intent.action_view, uri.parse(redirecturl));         startactivity(i);     } }); 

you can have own webview in place inside app, done / close button somewhere.. can track urls getting open in webview , stuff accordingly..user stay in app always..that solves purpose..

for tracking urls inside webview need register 1 webviewclient , ovveride below function

public boolean shouldoverrideurlloading (webview view, string url) 

have @ webview here , webviewclient here
