Deeplinking scheme conflict on Android

Issue

Related to #494

I've added a detailed comment about the issue here: #494 (comment)

While this might not be seen as a "bug", I feel the documentation and Example should be updated to show how to integrate this library on Android with existing deeplinking integration already in place.

It would be great if:

• The README was updated to mention how to handle auth redirect scheme, and existing deeplinking scheme on android
• The Example was updated to show how to support auth redirect sheme and existing deeplinking scheme on android (preferably using https://reactnavigation.org/)

Environment

• Your Identity Provider: Azure B2C
• Platform that you're experiencing the issue on: Android
• Are you using Expo? No

I am also currently having the problem that the app will show a choice for the user after successful login.
Any hint in the readme how to combine deep linking and OAuth2 flow would be appreciated.

@badsyntax thanks for the additional details! We've update the READMEs to reflect this change when implementing into a project that uses React Navigation deep linking.

I wasn't particularly happy with choosing a different scheme, so I found two different solutions:

1. If you have a defined list of hosts (ie scheme://host), you can filter them using pathPattern. Unfortunately there's no exclusion filter, so you can only filter specific paths.
2. You can create a custom deep link handler, I'm in the process of writing one myself. Most of the instructions are here: https://tech.justeattakeaway.com/2015/06/29/deep-linking-in-android-the-easy-way/, you also need to add app auth package to dependencies build.gradle (implementation 'net.openid:appauth:0.8.1', as of this comment), and import and call net.openid.appauth.RedirectUriReceiverActivity from the IntentHelper.java file.

Hopefully that's enough for anyone to figure out.
