Android project won't redirect back to app

[kcorrea96]

I'm a bit new to Azure & Xamarin.Forms and am trying to build a simple login application. I've gone through this tutorial multiple times and can't help but feel like I'm missing something. My application successfully brings me to the login page & allows me to enter my credentials, but when I click login it brings me to a blank screen (as seen below).

My android manifest looks like:

<uses-sdk android:minSdkVersion="25" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application> <activity android:name="microsoft.identity.client.BrowserTabActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="msal{app-id-of-native-aad-application}" android:host="auth" /> </intent-filter> </activity> </application> </manifest>

The redirect URI of my native app is set to msal{app-id-of-native-aad-application}://auth and the reply URI of my api (though from what i've seen this doesn't really matter) is set to https://localhost:44316/

I've changed the variables in the PCL as follows:

public static readonly string Tenant = "qalog.onmicrosoft.com"; // Domain/resource name from AD B2C
        public static readonly string ClientID = "{app-id-of-native-aad-application}"; // Application ID from AD B2C
        public static string PolicySignUpSignIn = "B2C_1_LoginApp"; // Policy name from AD B2C
        public static string PolicyEditProfile = "B2C_1_EditProf";
        public static string PolicyResetPassword = "B2C_1_ResetPass";

        public static readonly string[] Scopes = { "https://qalog.onmicrosoft.com/api/read", "https://qalog.onmicrosoft.com/api/user_impersonation"}; // Leave blank unless additional scopes have been added to AD B2C
        public static string ApiEndpoint = "https://fabrikamb2chello.azurewebsites.net/hello";

        public static string AuthorityBase = $"https://login.microsoftonline.com/tfp/{Tenant}/"; // Doesn't require editing
        public static string Authority = $"{AuthorityBase}{PolicySignUpSignIn}"; // Doesn't require editing

Am I missing something/does anyone have suggestions?

@kcorrea96 were you able to get the sample running as-in, without changing any of the properties?

I have Firefox set as my default browser and get the same blank screen after login and redirect if I choose "Open in Firefox" in the internal browser. It works if I stay in the internal browser or set Chrome as default and then open in an external Chrome instance.

@Livven @kcorrea96 Right now, MSAL has to have Chrome or Chrome custom tabs installed on the device in order to show the UI. We have embedded webview support coming, and you can try it out here and give us feedback and suggestions.

Any update on this @Livven @kcorrea96 ?

We now have the option for embedded webview in MSAL (which does not require custom tabs)...please check out the MSALv2.0.1-preview release.

We would love your feedback as well. You can reach me directly or open an issue on the MSAL repo.
Thanks!

@jennyf19 Thanks for the follow-up! Think it should solve AzureAD/microsoft-authentication-library-for-dotnet#589 as well too. I'll let you know if it works out.

just pass true in UIParent that tells android to use embedded browser.

App.UiParent = new UIParent(this, true);

@kcorrea96 @Livven @raasmasood Closing as the issue is resolved.Thank you
