Quickstart: Add chat with UI Library

  • Bài viết

Get started with Azure Communication Services UI Library to quickly integrate communication experiences into your applications. In this quickstart, learn how to integrate UI Library chat composites into an application and set up the experience for your app users.

Azure Communication Services UI Library renders a full chat experience right in your application. It takes care of connecting to Azure Communication Services chat services and updates a participant's presence automatically. As a developer, you need to decide about where in your app's user experience you want the chat experience to start and create only the Azure Communication Services resources as required.

Note

For detailed documentation and quickstarts about the web UI Library, see the web UI Library storybook.

  5. Select Finish.

    Screenshot that shows new project options and the Finish button selected.

Install the packages

Complete the following sections to install the required application packages.

Add a dependency

In your app-level UILibraryQuickStart/app/build.gradle file (in the app folder), add the following dependency:

dependencies {
    ...
    implementation 'com.azure.android:azure-communication-ui-chat:+'
    ...
}

Add Maven repositories

The Azure package repository is required to integrate the library.

To add the repository:

  1. In your project Gradle scripts, ensure that the following repositories are added. For Android Studio (2020.*), repositories is in settings.gradle, under dependencyResolutionManagement(Gradle version 6.8 or greater). For earlier versions of Android Studio (4.*), repositories is in the project-level build.gradle, under allprojects{}.

    // dependencyResolutionManagement
repositories {
    ...
    maven {
        url "https://pkgs.dev.azure.com/MicrosoftDeviceSDK/DuoSDK-Public/_packaging/Duo-SDK-Feed/maven/v1"
    }
    ...
}

  2. Sync your project with the Gradle files. To sync the project, on the File menu, select Sync Project With Gradle Files.

Add a button to activity_main.xml

In the app/src/main/res/layout/activity_main.xml layout file, add the following code to create a button to start the composite:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/startButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Launch"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Initialize the composite

To initialize the composite:

  1. Go to MainActivity.

  2. Add the following code to initialize your composite components for calling. Replace the string values for properties (kotlin) or functions (java) for endpoint, acsIdentity, displayName, accessToken, and ThreadId. Replace endpoint with the URL for your resource as provided by Azure Communication Services. Replace acsIdentity and accessToken with the values provided by Azure Communication Services when you created the access token, and use a relevant displayName. Replace ThreadId with the value returned when you created the thread. Add the user to the thread via REST API call or the az command-line interface client before you try to run the quickstart sample. Otherwise, the client is denied access to join the thread.

Prerequisites

Set up the project

Complete the following sections to set up the quickstart project.

Create a new Xcode project

In Xcode, create a new project.

  1. On the File menu, select New > Project.

  2. On Choose a template for your new project, select the iOS platform and select the App application template. The quickstart uses the UIKit storyboards.

    Screenshot that shows the Xcode new project dialog, with iOS and the App template selected.

  3. On Choose options for your new project, for the product name, enter UILibraryQuickStart. For the interface, select Storyboard. The quickstart doesn't create tests, so you can clear the Include Tests checkbox.

    Screenshot that shows setting new project options in Xcode.

Install the package and dependencies

  1. (Optional) For MacBook with M1, install and enable Rosetta in Xcode.

  2. In your project root directory, run pod init to create a Podfile. If you encounter an error, update CocoaPods to the current version.

  3. Add the following code to your Podfile. Replace UILibraryQuickStart with your project name.

    platform :ios, '14.0'

target 'UILibraryQuickStart' do
    use_frameworks!
    pod 'AzureCommunicationUIChat', '1.0.0-beta.4'
end

  4. Run pod install --repo-update.

  5. In Xcode, open the generated xcworkspace file.

Turn off Bitcode

In the Xcode project, under Build Settings, set the Enable Bitcode option to No. To find the setting, change the filter from Basic to All or use the search bar.

Screenshot that shows the Build Settings option to turn off Bitcode.

Initialize the composite

To initialize the composite:

  1. Go to ViewController.

  2. Add the following code to initialize your composite components for a chat. Replace <USER_ID> with user identifier. Replace <USER_ACCESS_TOKEN> with your access token. Replace <ENDPOINT_URL> with your endpoint URL. Replace <THREAD_ID> with your chat thread ID. Replace <DISPLAY_NAME> with your name. (The string length limit for <DISPLAY_NAME> is 256 characters).

    import UIKit
import AzureCommunicationCommon
import AzureCommunicationUIChat

class ViewController: UIViewController {
    var chatAdapter: ChatAdapter?

    override func viewDidLoad() {
        super.viewDidLoad()

        let button = UIButton()
        button.contentEdgeInsets = UIEdgeInsets(top: 10.0, left: 20.0, bottom: 10.0, right: 20.0)
        button.layer.cornerRadius = 10
        button.backgroundColor = .systemBlue
        button.setTitle("Start Experience", for: .normal)
        button.addTarget(self, action: #selector(startChatComposite), for: .touchUpInside)

        button.translatesAutoresizingMaskIntoConstraints = false
        self.view.addSubview(button)
        button.widthAnchor.constraint(equalToConstant: 200).isActive = true
        button.heightAnchor.constraint(equalToConstant: 50).isActive = true
        button.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        button.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    }

    @objc private func startChatComposite() {
        let communicationIdentifier = CommunicationUserIdentifier("<USER_ID>")
        guard let communicationTokenCredential = try? CommunicationTokenCredential(
            token: "<USER_ACCESS_TOKEN>") else {
            return
        }

        self.chatAdapter = ChatAdapter(
            endpoint: "<ENDPOINT_URL>", identifier: communicationIdentifier,
            credential: communicationTokenCredential,
            threadId: "<THREAD_ID>",
            displayName: "<DISPLAY_NAME>")

        Task { @MainActor in
            guard let chatAdapter = self.chatAdapter else {
                return
            }
            try await chatAdapter.connect()
            let chatCompositeViewController = ChatCompositeViewController(
                with: chatAdapter)

            let closeItem = UIBarButtonItem(
                barButtonSystemItem: .close,
                target: nil,
                action: #selector(self.onBackBtnPressed))
            chatCompositeViewController.title = "Chat"
            chatCompositeViewController.navigationItem.leftBarButtonItem = closeItem

            let navController = UINavigationController(rootViewController: chatCompositeViewController)
            navController.modalPresentationStyle = .fullScreen

            self.present(navController, animated: true, completion: nil)
        }
    }

    @objc func onBackBtnPressed() {
        self.dismiss(animated: true, completion: nil)
        Task { @MainActor in
            self.chatAdapter?.disconnect(completionHandler: { [weak self] result in
                switch result {
                case .success:
                    self?.chatAdapter = nil
                case .failure(let error):
                    print("disconnect error \(error)")
                }
            })
        }
    }
}

  3. If you choose to put chat view in a frame that's smaller than the screen size, we recommend the minimum width of 250 and the minimum height of 300.

Run the code

To build and run your app on the iOS simulator, select Product > Run. You can also use the (⌘-R) keyboard shortcut. Then, try out the chat experience on the simulator.

  1. Select Start Experience.
  2. The chat client joins the chat thread, and you can start typing and sending messages.
  3. If the client can't join the thread and you see chatJoin failed errors, verify that your user's access token is valid and that the user was added to the chat thread by REST API call or by using the az command-line interface.

Clean up resources

If you want to clean up and remove an Azure Communication Services subscription, you can delete the resource or resource group.

Deleting the resource group also deletes any other resources associated with it.
