In Android I have a solution for using the native browser to perform an OAuth2 sign in.  There are some limititions however.

In general to use this you need an activity which has an intent filter to consume the redirect URL.  This works best if you use a custom URI scheme.  Google, Yahoo, and Facebook (as well as other I'm sure) only allow redirects to http or https.  This means that unless you are using a third party to redirect a custom schema the browser my preempt your application and consume the redirect.  Other services such as KeyCloak and Spotify allow custom schemas and these work perfectly with my solution.

If we document the limitations of the Intent and when using an Intent vs using a WebView is appropriate, is a solution with these limitations adequate? I think it is.



PS: a link to my poc :
PPS:  You can use this on the KeyCloakHelper in Shoot and Share by adding `setWithIntent(true)` to the configuration in that class.
