About the Sample

The MSAL Android library gives your app the ability to begin using the Microsoft identity platform by supporting Azure Active Directory and Microsoft Accounts in a converged experience using industry standard OAuth2 and OpenID Connect protocols.

This sample walks you through the process of integrating authentication with Microsoft Identity Platform (formerly Azure Active Directory for developers) in your android application. In this sample we'll walk you through the code you need to write in the various lifecycle events of your app to achieve the following objectives.

• Sign-in a user
• Device-wide SSO and Conditional Access support through the Auth Broker
• Select between Single Account Mode and Multiple Account Mode
• Get a token for the Microsoft Graph
• Call the Microsoft Graph
• Sign out the user

Scenario

This sample app is a multi-tenant app, which means that it can sign-in users from any Azure AD tenant and Microsoft Accounts. It also demonstrates how a developer can build apps to connect with enterprise users and access their Azure + O365 data via Microsoft Graph. During the auth flow, the users will be required to sign-in first, if it's their first time signing-in to the app, the user would be asked to consent to the permissions required by the application.

The majority of the logic in this sample shows how to sign-in an end user and make a call to the Microsoft Graph to get basic information about the signed-in user.

Broker Authentication using MSAL

Microsoft provides applications for every mobile platform that allow for the bridging of credentials across applications from different vendors and for enhanced features that require a single secure place from where to validate credentials. These are called brokers. The brokers available for Android are Microsoft Authenticator and Company Portal. Learn more about Brokers here.

The MSAL for Android will automatically use the broker if they are present on the device.

If you have older versions of Microsoft Authenticator app or Company portal app installed in the device where this sample application will be run, then the user might not be able to test the scenarios presented here. Please make sure that you have installed the latest version of Microsoft Authenticator or Company Portal on your device.

Single Account Mode

In the Single Account Mode, only one user can sign into the application at a time. If the app wants to support just one signed-in user, it is recommended to use the Single Account Mode.

The following code snippet from SingleAccountModeFragment class shows how the application is set to the Single Account Mode in the code:

PublicClientApplication.createSingleAccountPublicClientApplication(
    getContext(),
    R.raw.auth_config_single_account);

In the auth_config_single_account.json file, the account_mode is set as following:

"account_mode" : "SINGLE",

Multiple Account Mode

In the Multiple Account Mode, the application supports multiple accounts and can switch between user accounts and get data from that user's account.

Code snippet from MultipleAccountModeFragment class shows how the application is set in the Multiple Account Mode in the code:

PublicClientApplication.createMultipleAccountPublicClientApplication(getContext(),
    R.raw.auth_config_multiple_account);

How to run this sample

To run this sample, you'll need:

• Android SDK
• An internet connection
• An Azure Active Directory (Azure AD) tenant. For more information on how to get an Azure AD tenant, see How to get an Azure AD tenant
• One or more user accounts in your Azure AD tenant.

Steps to Run the app

This sample ships with a default redirect_uri configured in the AndroidManifest.xml. In order for the default redirect_uri to work, this project must be built with the debug.keystore located in the gradle/ directory. To configure signing in Android Studio, see Sign Your App.

Step 1: Clone the code

From your shell or command line:

   git clone https://github.com/Azure-Samples/ms-identity-android-kotlin.git

The following steps have been carried out for android studio, but you can choose and work with any editor of your choice.

Open Android Studio, and select open an existing Android Studio project. Find the cloned project and open it.

Step 2: Run the sample

From menu, select Run > Run 'app'. Once the app launches,

1. Click on the hamburger icon

   • Single Account: Select this to explore Single Account Mode

   • Multiple Account: Select this to explore Multiple Account Mode.

2. Click on sign-in, it takes you to add account page.

3. Add one or more accounts as per the device mode, and sign in with your test account.

4. Once successfully signed-in, basic user details will be displayed.

To explore more about the application, follow on screen options.

This sample application is configured to run out-of-the-box. To register your own application and run the sample with those settings, follow below steps.

Register your Own Application (Optional)

To begin registering your app, start at the Azure portal

To create an app registration,

1. Click New Registration.

2. Name your app, select the audience you're targeting, and click Register.

3. In the Overview > Sign in users in 5 minutes > Android.

   • Click on Make this changes for me.
   • Enter the Package Name from your Android Manifest.
   • Generate a Signature Hash. Follow the instructions in the portal.

4. Hit the Make updates button. Note the MSAL Configuration as it is used later in AndroidManifest.xml and auth_config.json.

Configure the sample application with your app registration by replacing the sample code in auth_config.json and AndroidManifest.xml

1. Copy and paste the MSAL Configuration JSON from the Azure portal into auth_config.json.

2. Inside the AndroidManifest.xml, replace android:host and android:path with the same info saved in above step. - auth_config.json contains this information as a reference inside the redirect_uri field. - The Signature Hash should NOT be URL encoded in the AndroidManifest.xml. Refer Azure Active Directory Android Quickstart for more details

From menu, select Build > Clean Project and Run > Run 'app'.

About the code

The following code fragments walk through features that MSAL can implement.

SingleAccountModeFragment class

Contains code showing how the Single Account Mode is implemented. The includes authentication, obtaining the token, and making a Graph API call using the obtained token.

The following steps give you more details.

1. Create a SingleAccount PublicClientApplication:

   PublicClientApplication.createSingleAccountPublicClientApplication(
       context as Context,
       R.raw.auth_config_single_account,
       object : IPublicClientApplication.ISingleAccountApplicationCreatedListener {
           override fun onCreated(application: ISingleAccountPublicClientApplication) {
           }
   
           override fun onError(exception: MsalException) {
           }
       })

2. Signing in a user:

   mSingleAccountApp!!.signIn(activity as Activity, "", getScopes(), getAuthInteractiveCallback())

3. Acquiring token:

   • Interactive:

   mSingleAccountApp!!.acquireToken(activity!!, getScopes(), getAuthInteractiveCallback())

   • Silent:

   mSingleAccountApp!!.acquireTokenSilentAsync(getScopes(), AUTHORITY, getAuthSilentCallback())

4. Calling Graph API to get basic user details and displaying data:

   private fun callGraphAPI(authenticationResult: IAuthenticationResult) {
       MSGraphRequestWrapper.callGraphAPIWithVolley(
           context as Context,
           msgraph_url.text.toString(),
           authenticationResult.accessToken,
           Response.Listener<JSONObject> { response ->
               /* Successfully called graph, process data and send to UI */
               Log.d(TAG, "Response: $response")
               displayGraphResult(response)
           },
           Response.ErrorListener { error ->
               Log.d(TAG, "Error: $error")
               displayError(error)
           })
   }

5. Sign-out:

   mSingleAccountApp!!.signOut(object : ISingleAccountPublicClientApplication.SignOutCallback {
       override fun onSignOut() {
       }
   
       override fun onError(exception: MsalException) {
       }
   });

   When sign-out is performed it removes the signed-in account and cached tokens from this app.

MultipleAccountModeFragment class

Contains code showing how the Multiple Account Mode is implemented. The includes authentication, obtaining the token, and making a Graph API call using the obtained token.

1. Create a MultipleAccount PublicClientApplication:

   PublicClientApplication.createMultipleAccountPublicClientApplication(
       context as Context,
       R.raw.auth_config_multiple_account,
       object : IPublicClientApplication.IMultipleAccountApplicationCreatedListener {
           override fun onCreated(application: IMultipleAccountPublicClientApplication) {
               mMultipleAccountApp = application
           }
   
           override fun onError(error: MsalException){
           }
       });

2. Acquiring token:

   • Interactive:

   mMultipleAccountApp!!.acquireToken(activity as Activity, getScopes(), getAuthInteractiveCallback())

   • Silent:

   mMultipleAccountApp.acquireTokenSilentAsync(getScopes(),
       accountList.get(accountListSpinner.getSelectedItemPosition()),
           AUTHORITY,
           getAuthSilentCallback());

3. Get Accounts:

   mMultipleAccountApp!!.acquireTokenSilentAsync(
               getScopes(),
               accountList!![account_list.selectedItemPosition],
               AUTHORITY,
               getAuthSilentCallback()
           )

4. Remove account:

    mMultipleAccountApp!!.removeAccount(
       accountList!![account_list.selectedItemPosition],
       object : IMultipleAccountPublicClientApplication.RemoveAccountCallback {
           override fun onRemoved() {
   
           }
   
           override fun onError(exception: MsalException) {
   
           }
       })
