I have an Ionic app (Ionic 6, Capacitor 3, Angular 13) and for Okta authentication I am using the ionic-appauth library. Everything is working ok on my iOS device but when I login on Android I get the error:
Web page not available
The web page at com.oktapreview.myCompany:/callback?code=XXXXXX could not be loaded because:
I have no idea whether this is to do with the settings I have in my app on the Okta dashboard which are:
It seems like your scheme isn’t being registered in Capacitor. It also seems like you are following the instructions for configuring things. Maybe you can try creating a brand new app (with the Ionic CLI and OktaDev Schematics) and see if that works? If it does, use something like SmartSynchronize to compare the code.
I’ve tried comparing the two apps but we have so much more functionality and dependencies in our app I am not really sure what to do. I re-added the schematics to our app from scratch and tried the login and tabs pages but they failed with the same error.
If you can think of anything that might be causing my scheme error to occur in Android please let me know!
Our app still makes use of the cordova-plugin-inappbrowser plugin. If I add that to the package.json of the sample application I created with the OktaDev Schematics and then run npm install and re-build it, the app returns exactly the same error I have been getting when you log in.
Does that make any sense to you at all @mraible ? I thought the InAppBrowser plugin had no affect on an app at all unless you specifically use it but simply adding it as a dependency to the app results in the error occuring.
I’m wondering if adding it it affects the way usernames and passwords are stored and pre-filled or something because without the plugin added, when I get to the Okta screen my username is pre-filled ok and I always have to type the password in but when I add the plugin the username is blank (although there is an auto-fill option at the bottom of the screen) and there is an auto-fill for the password - does that make any sense?
That has had no effect - I get the original error as soon as I login to Okta. Is there anything else I need to do do you think? If I cannot get this to work my only other option is to remove the InAppBrowser plugin from our app but that will require a lot of additional re-work so my preference would be to try and get this working with it in.
What I don’t understand is that simply having the InAppBrowser installed in the app affects this OktaLogin callback. I’m not telling the app to use the InAppBrowser at this point - simply adding it as a dependency makes the callback fail. Why is that? Does that make sense?
In case I’m not being clear this is what generates the error:
Add the InAppBrowser dependency into package.json and run npm install and rebuild the app.
This results in the callback error on Okta Login i.e simply adding the InAppBrowser plugin and not making any reference to it anywhere in the code. This only affects Android. iOS works ok.
My problem is that our app does need to have the InAppBrowser plugin as a dependency (for use elsewhere in the app). I don’t understand why simply having the plugin installed in the app causes this issue?
I ran into this same issue today and tried to use the same solution as you. Unfortunately, I get the following error when trying to run with Pixel XL API 31.

Installing @capacitor/browser got me past this. I tried @capacitor-community/http and was able to get rid of Cordova plugins too. Works great on iOS, but not Android.
