Hello Everyone,
I've cloned my website into a Xamarin webview app and i'm looking out to call UPI apps installed on my phone. Payment gateway provider is Razorpay. Listed below are the things i've tried.
- The local installed UPI app is accessible through the website directly (https://greycats.tech).
- Local UPI app is accessible through a react webview app.
- I've tried adding some intent filters by researching , but it seems that i'm going wrong with that minorly.
- I tried to identify the URL but there's no URL when the razorpay form generates.
Is there a way that i can allow my webview app to call the payment provider apps in my phone ?

You can try to use Xamarin.Essentials: Launcher to open another app. I'm not clear about your webview, what's your expected behavior to to call the payment provider apps? As noted in the Q&A FAQ: How to write a quality question

Thankyou for your reply.
My use case is. The webview all will actually be a multivendor store and the expected flow will be.A customer purchases a product --> goes to checkout --> selects an option to pay via UPI --> the UPI app opens up dynamically with the payment inputs like it does on normal chrome.
For a live use case, you can visit https://greycats.tech and select the payment as Google pay or phone pay upon checkout (DO NOT MAKE THE PAYMENT) try just for use case.
Note : have already tried Launcher as well as tried adding the manual URL which shouldn't be a case.

2022-08-25T05:31:56.283+00:00 You can pay the order by your website in any other browsers but not in the webview, right? Does this issue only occur in Android? You could check your payment URL to the third party provider and determine if the link target is
_blank. If so, you need to setwebView.Settings.SetSupportMultipleWindows(true)for Android Platform in a custom renderer. -

I've uploaded by code to Github, you can download the same via this link :
https://github.com/GreyCatsTech/YorderAppWould request you to download any UPI apps on your phone to check the redirection.

2022-08-30T03:14:18.137+00:00 Hi @Yasser Qureshi , I checked you sample, there is no customrenderer under Android platform. You can try to add the following code for the Android platform:
[assembly: ExportRenderer(typeof(WebView), typeof(CustomWebviewRenderer))] namespace YorderApp.Droid { public class CustomWebviewRenderer: WebViewRenderer { protected override void OnElementChanged(ElementChangedEventArgs<WebView> e) { base.OnElementChanged(e); Control.Settings.SetSupportMultipleWindows(true); } } }For more details, you can refer to Customizing a WebView - Xamarin | Microsoft Learn
I can go to the payment page, a customer purchases a product --> goes to checkout --> selects an option to pay via UPI ->enter UPI account, there is a page asking to valid VPA, is this your expected behavior? Please test and let me know the test result. And you said it didn't work before, could you please describe more?

This is a normal behaviour where the app asks to enter upi account.
What i need currently is. Instead of entering the upi account, the customer should be redirected to the UPI app installed on their phone directly. Like a callback action. -

I tried implementing this solution. Unfortunately, failed to work again, if possible, can you please add the code to the repository so I can check where exactly I'm going wrong?
