ERR_UNKNOWN_URL_SCHEME when opening Google Maps links

I have an issue with Google Maps links in my app. My app is basically just a website that I turned into an social medie app using the Kodular WebViewer.

Users can add their own Google Maps links, and these links should open directly in the Google Maps app. In the builted APK I get the error “ERR_UNKNOWN_URL_SCHEME” and the link does not open.

I added a screenshot of my setup. Does anyone know how to fix this so the WebViewer can open Google Maps links properly?

Thanks!

Hi dear,

This issue has already been discussed several times.

What you’re asking for is the DeepLink function, which is included in this extension.

thank you,
but the extancion doest work for me. I have the same problem again.

Can you show us what you did?

Okay, so it finally worked now, which is nice, I guess. But there’s another problem: I still have my Login page and Logout page on different URLs then the rest of the App, and they also open in the external browser now. I don’t want that. How can I fix this? Thank you very much for your help

Very well :partying_face:

Since you didn’t specify how you solved it, I’d ask you to give us a recap of how your setup looks now.

I just downloaded the extension and pressed the follow deep links button. But now i have the problem what i mentioned ealier that i have the Login page and Logout page on different URLs then the rest of the App, and they also open in the external browser now. But I don’t want that. Can you help me please

My Setup (I tried this but i dont know if its right:

There’s no need to do that,
Enable deep links and follow this example

in GoToURL enter your site and it should work.

I dont understand what you mean. I dont have any buttons just the webviewer with an url. But i have the problem that my login page (website) has another url then the main part of my website and the only option is to put one url in the webviewer instead of two. So now it opens the login page (that has another url then the main website) in an external browser. I dont want that, how can i fix it?

Hi Tristan,

Forgive me, I didn’t specify that the button wasn’t needed.

The fact that it’s opening pages in an external browser makes me think you enabled UseExternalBrowser.

try this project by inserting your site.

Yea i tried it but when i disable UseExternalBrowser then the deeplink function doesnt work again. What should i do? Thank You very much for your help!!

hmm, in customWebViewer there is no UseExternalBrowser

no in the normal webviewer

:grin: In the regular browser, deep links don’t work.
Otherwise, I wouldn’t have insisted on using customWebViewer.

No i mean i have to turn the external Browser function from the normal Webviewer on to follow the deeplinks with the customWebViewer. When i turn the external browser on the normal Webviewer off then the custom webviewer with the deeplink function doesnt work

You don’t need any other webViewer besides CustomWebViewer.

But you cant put the home url to the custom webviewer or am I wrong?

By using the GoToURL function in ScreenInitialize, you can emulate the home function of the native webViewer.

I cant find the VA_CustomWebViewer

You have to create it yourself, it’s just an empty Vertical Arrangement.
