Platform Wiring

This section describes the minimal code necessary to handle Okta authentication related redirects when using the Okta Xamarin Sdk.

Android

To handle Okta authentication redirects on Android do the following:

Update your MainActivity to extend OktaMainActivity<App>.
```
public class MainActivity : OktaMainActivity<App>
```

Override the OnSignInCompleted and OnSignOutCompleted methods.

public override void OnSignInCompleted(object sender, SignInEventArgs signInEventArgs)
{
    // for demo purposes go to the profile page
    Shell.Current.GoToAsync("//ProfilePage", true);
}

public override void OnSignOutCompleted(object sender, SignOutEventArgs signOutEventArgs)
{
    // for demo purposes go to the profile page
    Shell.Current.GoToAsync("//ProfilePage", true);
}

Your completed MainActivity.cs should look similar to the following:

 [Activity(Label = "MyOktaApp", Icon = "@mipmap/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize)]
 public class MainActivity : OktaMainActivity<App>
 {
     public override void OnSignInCompleted(object sender, SignInEventArgs signInEventArgs)
     {
         // for demo purposes go to the profile page
         Shell.Current.GoToAsync("//ProfilePage", true);
     }

     public override void OnSignOutCompleted(object sender, SignOutEventArgs signOutEventArgs)
     {
         // for demo purposes go to the profile page
         Shell.Current.GoToAsync("//ProfilePage", true);
     }
 }

Create a new Activity to intercept Login redirects, this example uses LoginCallbackInterceptorActivity.

Replace the activity implementation with the following code:

[Activity(Label = "LoginCallbackInterceptorActivity", NoHistory = true, LaunchMode = LaunchMode.SingleInstance)]
[
	IntentFilter
	(
		actions: new[] { Intent.ActionView },
		Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
		DataSchemes = new[] { "my.app.login" },
		DataPath = "/callback"
	)
]
public class LoginCallbackInterceptorActivity : OktaLoginCallbackInterceptorActivity<MainActivity>
{
}

Note that the value specified for DataSchemes MUST match the prefix entered in step 6 of Register Redirects and the DataPath MUST match the suffix.

Create a new Activity to intercept Logout redirects, this example uses LogoutCallbackInterceptorActivity.

Replace the activity implementation with the following code:

[Activity(Label = "LogoutCallbackInterceptorActivity", NoHistory = true, LaunchMode = LaunchMode.SingleInstance)]
[
	IntentFilter
	(
		actions: new[] { Intent.ActionView },
		Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
		DataSchemes = new[] { "my.app.logout" },
		DataPath = "/callback"
	)
]
public class LogoutCallbackInterceptorActivity : OktaLogoutCallbackInterceptorActivity<MainActivity>
{
}

Note that the value specified for DataSchemes MUST match the prefix entered in step 8 of Register Redirects and the DataPath MUST match the suffix.

iOS

To handle Okta authentication redirects on iOS do the following:

Modify your AppDelegate class to extend OktaAppDelegate<App>.

In the FinishedLaunching method add event handlers for the SignInCompleted and SignOutCompleted events, this example navigates to the ProfilePage, you should provide logic appropriate for your application:

OktaContext.AddSignInCompletedListener(OnSignInCompleted);
OktaContext.AddSignOutCompletedListener(OnSignOutCompleted);

A complete AppDelegate example follows:

[Register("AppDelegate")]
public partial class AppDelegate : OktaAppDelegate<App>
{
    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
        bool result = base.FinishedLaunching(app, options);
        OktaContext.AddSignInCompletedListener(OnSignInCompleted);
        OktaContext.AddSignOutCompletedListener(OnSignOutCompleted);

        return result;
    }
    
    public void OnSignInCompleted(object sender, SignInEventArgs signInEventArgs)
    {
        // for demo purposes go to the profile page
        Shell.Current.GoToAsync("//ProfilePage", true);
    }
    
    public void OnSignOutCompleted(object sender, SignOutEventArgs signOutEventArgs)
    {
        // for demo purposes go to the profile page
        Shell.Current.GoToAsync("//ProfilePage", true);
    }
}

Refresh Tokens

To receive a refresh token along with id and access tokens do the following:

Ensure that Refresh Token is checked in the Allowed grant types section of your application.
- Sign in to the admin dashboard for your application.
- Click on Applications and go to General Settings > Application > Allowed grant types.
- Check the box next to Refresh Token.
Specify the offline_access scope along with the default scopes in your config file.
- Android:
  - Add the following element inside the Okta element of the file Assets/OktaConfig.xml.
```
<Scope>openid profile offline_access</Scope>
```
- iOS:
  - Add the Scope property to the OktaConfig.plist file.
    - Property = Scope
    - Type = String
    - Value = openid profile offline_access

Secure Storage

Okta Xamarin Sdk provides convenience methods to store authentication state in platform specific secure storage. To enable secure storage do the following:

Android:
- To use secure storage on Android no special setup is required.
iOS
- To use secure storage on iOS you must enable keychain:
  - Using Visual Studio open the file Entitlements.plist file found in the root of your Xamarin iOS project.
  - Select Keychain in the list of Entitlements
  - Check the box labeled Enable Keychain

    // ... additional custom logic  
}

// using AddGetUserCompletedListener
OktaContext.AddGetUserCompletedListener((sender, getUserEventArgs) => 
{
    object userInfo = getUserEventArgs.UserInfo; // object type varies depending on which variation of the GetUser method is used

    // ... additional custom logic  
})

IntrospectStarted event

The OktaContext.Current.IntrospectStarted event is raised before token introspection. To execute code when the IntrospectStarted event is raised, add an event handler to the OktaContext.Current.IntrospectStarted event.

// directly 
OktaContext.Current.IntrospectStarted += (sender, introspectEventArgs) =>
{
    string token = introspectEventArgs.Token;
    TokenKind tokenKind = introspectEventArgs.TokenKind;

    // ... additional custom logic
}

// using AddIntrospectStartedListener
OktaContext.AddIntrospectStartedListener((sender, introspectEventArgs) =>
{
    string token = introspectEventArgs.Token;
    TokenKind tokenKind = introspectEventArgs.TokenKind;

    // ... additional custom logic    
})

IntrospectCompleted event

The OktaContext.Current.IntrospectCompleted event is raised after token introspection. To execute code when the IntrospectCompleted event is raised, add an event handler to the OktaContext.Current.IntrospectCompleted event.

// directly 
OktaContext.Current.IntrospectCompleted += (sender, introspectEventArgs) =>
{
    string token = introspectEventArgs.Token;
    TokenKind tokenKind = introspectEventArgs.TokenKind;

    // ... additional custom logic
}

// using AddIntrospectCompletedListener
OktaContext.AddIntrospectCompletedListener((sender, introspectEventArgs) =>
{
    string token = introspectEventArgs.Token;
    TokenKind tokenKind = introspectEventArgs.TokenKind;

    // ... additional custom logic    
})

RenewStarted event

The OktaContext.Current.RenewStarted event is raised before token renewal begins. To execute code when the RenewStarted event is raised, add an event handler to the OktaContext.Current.RenewStarted event.

// directly
OktaContext.Current.RenewStarted += (sender, renewEventArgs) =>
{
    IOktaStateManager stateManager = renewEventArgs.StateManager;

    // ... additional custom logic
}

// using AddRenewStartedListener
OktaContext.AddRenewStartedListener((sender, renewEventArgs) =>
{
    IOktaStateManager stateManager = renewEventArgs.StateManager;

    // ... additional custom logic
})

RenewCompleted event

The OktaContext.Current.RenewCompleted event is raised after token renewal completes. To execute code when the RenewCompleted event is raised, add an event handler to the OktaContext.Current.RenewCompleted event.

// directly
OktaContext.Current.RenewCompleted += (sender, renewEventArgs) =>
{
    IOktaStateManager stateManager = renewEventArgs.StateManager;

    // ... additional custom logic
}

// using AddRenewCompletedListener
OktaContext.AddRenewCompletedListener((sender, renewEventArgs) =>
{
    IOktaStateManager stateManager = renewEventArgs.StateManager;

    // ... additional custom logic
})

RenewException event

The OktaContext.Current.RenewException event is raised when an exception occurs during token renewal. To execute code when the RenewException event is raised, add an event handler to the OktaContext.Current.RenewException event.

// directly
OktaContext.Current.RenewException += (sender, renewExceptionEventArgs) =>
{
    Exception exception = renewExceptionEventArgs.Exception;

    // ... additional custom logic
}

// using AddRenewExceptionListener
OktaContext.AddRenewExceptionListener((sender, renewExceptionEventArgs =>
{
    Exception exception = renewExceptionEventArgs.Exception;

    // ... additional custom logic
}))

Accessing Tokens Using OktaStateManager class

After authentication completes, use OktaContext.Current.StateManager to access tokens for the current authenticated Okta session.

// get access token
string accessToken = OktaContext.Current.StateManager.GetAccessToken();

// get refresh token
string refreshToken = OktaContext.Current.StateManager.GetRefreshToken();

// get Id token
string idToken = OktaContext.Current.StateManager.GetIdToken();

BearerToken and BearerTokenClaims classes

When the SignInCompleted event is raised the EventArgs parameter instance is of type SignInEventArgs which provides access to an instance of the OktaStateManager class. Use code similar to the following to read the authentication state and access the bearer token claims when sign in completes:

OktaContext.AddSignInCompletedListener((sender, args) =>
{
    SignInEventArgs signInEventArgs = (SignInEventArgs)args;
    IOktaStateManager oktaStateManager = signInEventArgs.StateManager; //
    BearerToken bearerToken = new BearerToken(oktaStateManager.AccessToken);
    BearerTokenClaims claims = BearerTokenClaims.FromBearerToken(bearerToken);

    // Access claims properties
    Console.WriteLine(claims.Issuer);
    Console.WriteLine(claims.Subject);
    Console.WriteLine(claims.Audience);
    Console.WriteLine(claims.ExpirationTime);
});
