Which SDK this is regarding: com.auth0.android:auth0:2.7.0 Running on Android phones version 29 and up I am having trouble with logging in using Auth0’s social login (Fitbit) inside a Chrome custom tab on Android. When the social login goes to redirect back to my app using my specified Auth0 callback URL, it goes to a page that says “Not found” in plain text with no other information. My specified callback URL is https://{my-tenant}.eu.auth0.com/android/{my-android-package}/callback. When I open the failing URL in Chrome proper, it looks like this: https://{my-tenant}.eu.auth0.com/android/{my-android-package}/callback?code=L…k&state=J…E (information redacted by the …s). I am using a CredentialsManager to hold the credentials that should be returned by the login process. I have tried the following to rectify the problem: - Clearing the browser cache (Chrome in my simulation, Firefox on my physical phone) - Clearing the CredentialsManager on Activity creation (which then triggers the login) - The problem also occurs when using the Auth0 standard login Any help in getting my app to login correctly is appreciated! ---

Hey there @lizfltn! Thanks for the detailed description of the issue you’re seeing 😃 > [@lizfltn](#): > > The problem also occurs when using the Auth0 standard login Considering this is happening without a social provider involved, I don’t think there’s an issue there - This is good news as that can get tricky! I believe this is related to the defining your app’s `auth0Scheme` as `https` like: ```auto manifestPlaceholders = [auth0Domain: "@string/com_auth0_domain", auth0Scheme: "https"] ``` Instead, you might try setting this to a custom one (In our sample apps we use `demo` for example).

In some devices it will prompt the user with a “Open application with…” and give you a list of apps that you can open it with. If you happen to select the browser, it will try to open ‘[https://subdomain.eu.auth0.com/android/com.{applicationId}/callback](https://subdomain.eu.auth0.com/android/com.%7BapplicationId%7D/callback)’ which will fail since what you want is really to return to the app. Changing the scheme will prevent the brow… > **[GitHub - auth0/Auth0.Android: Android toolkit for Auth0 API](https://github.com/auth0/Auth0.Android#a-note-about-app-deep-linking)** > > Android toolkit for Auth0 API.

Thank you! Using a custom scheme (in my case, “app”) seems to have fixed my problem! ---
