Redirecting to Web URL from mobile app through Xamarin.Forms.Essential

Prasanth Kumar 21

I'm currently facing an issue with the mobile application. While clicking the "sign-up" button on our mobile app, usually it will redirect the user to the sign-up page via browser. But what happens now is that, when the sign-up button is clicked, the browser opens as usual but instead of loading the sign-up page, "login" page gets loaded on the browser. What is to be noted here is that the URL when redirected by the application is for the sign-up page. Whereas in-between, it automatically changes to the URL of the login page. I've checked the code thoroughly and it clearly has the URL of the sign-up page.

Angular is used for Web application.

Hi, PrasanthKumar-9388. Do you use the Xamarin.Essentials.Browser api to perform the work in your project? I create a basic demo to test the function, it works fine. Try to add a breakpoint to debug to check the uri.

private async void Button_Clicked(object sender, EventArgs e) { try { await Browser.OpenAsync(new Uri("xxx"), BrowserLaunchMode.SystemPreferred); } catch (Exception ex) { // An unexpected error occured. No browser may be installed on the device. } }

Yes, I am using Xamarin.Essentials.Browser API.

While debugging, it shows the correct URL. But after redirected to browser, it shows different URL.

For instance, i have given URL as https://XXXX.net/#/**signup**", but it redirects to the https://XXXX.net/#/**login**"

Hi, try to load the signup url in a browser directly to check if it will work fine.

Yes, signup URL is working fine when hit directly. But while going through the mobile app it redirects to the login page.

Browser.OpenAsync is just to open the browser and load the url, it'll not change the url. Is the url you test a public url like https://www.google.com. Would you mind sharing the url for test to reproduce the issue?

And which platform did you face the problem?

revflexproductionsit.azurewebsites.net

This is the URL. But while redirecting from mobile, it is going to https://revflexproductionsit.azurewebsites.net/#/

On both iOS & Android, i am facing this issue.

Hi, I tested the url and faced the issue as you described. The link you posted is 'https://revflexproductionsit.azurewebsites.net/#/signup-tester', it will changes to 'https://revflexproductionsit.azurewebsites.net/#/login' when I load it in chorme broswer on the pc. There may be something wrong with the url.

To load the sign-up page, please use the 'https://revflexproductionsit.azurewebsites.net/#/signup-client' address instead. I've tested it in the project, it works fine.

private async void Button_Clicked(object sender, EventArgs e) { try { await Browser.OpenAsync(new Uri("https://revflexproductionsit.azurewebsites.net/#/signup-client"), BrowserLaunchMode.SystemPreferred); } catch (Exception ex) { // An unexpected error occured. No browser may be installed on the device. } }

Hi,

First of all, Thanks for your help.

There is no need to redirecting the user to Client signup page. Requirement is to redirect the user to Tester signup.

But the url seems to be not valid, you could click the following url to check that. It'll be changed automatically after the address is loaded.

Click the url: https://revflexproductionsit.azurewebsites.net/#/signup-tester
