Hi benmesza,

we had the same issue, but thanks to the Ionic_AppAuth demos we solved it. https://github.com/wi3land/ionic-appauth/tree/master/demos/angular-cordova

Just update cordova-plugin-inappbrowser with this command: ionic cordova plugin add https://github.com/Onegini/cordova-plugin-inappbrowser.git

Best regards, Heimo

We're having a similar issue. @Heimo001 - I'm not quite following why your suggested fix would address this custom url scheme issue. Can you explain how the fix addresses the problem?

[Heimo001]

I don't know what exactly is fixing this issue, because that repository is quite old, but it is due to an issue in the in app browser. You can test this with your system bwowser. When you type in your custom url scheme in chrome for example, you get refirected to your app.

So we compared our project with the ionic-appauth demos and that was the only difference and we adapted that to our project and it works now.

Just try it

I checked this out.

The old repo works because it's doing a 'cordova.getActivity().startActivity(intent)', whereas the modern one tries to do a callbackContext.sendPluginResult(result) with the custom URL scheme, if the AllowedSchemes platform preference is specified. But even doing that doesn't get my app around the issue.

I stumbled onto this issue\pull request for cordova-plugin-safariviewcontroller v2.0.1: https://github.com/EddyVerbruggen/cordova-plugin-safariviewcontroller/pull/180/files

Until that gets merged\released, adding this to my AndroidManifest.xml gets my app around the issue: `

This is still an issue for us as well. Using: cordova-android@11.0.0 on device with Android 11 targeting SDK 31 works with the fix from @Heimo001

works on 'Android 9' with InAppBrowser v5.0.0. Trying to implement Auth0 with cordova and angular. Regards, Ivan
