Azure Communication UI Mobile Library for Android

Azure Communication UI Mobile Library is an Azure Communication Services capability focused on providing UI components for common business-to-consumer and business-to-business calling interactions.

Getting Started

Get started with Azure Communication Services by using the UI Library to integrate communication experiences into your applications. For detailed instructions to quickly integrate the UI Library functionalities visit the Quick-start Documentation.

Prerequisites

• An Azure account with an active subscription. Create an account for free.
• An OS running Android Studio.
• A deployed Communication Services resource. Create a Communication Services resource.
• Azure Communication Services Token. See example

Install the packages

In your app level (app folder) build.gradle, add the following lines to the dependencies and android sections.

android {
    ...
    packagingOptions {
        pickFirst  'META-INF/*'
    }
    ...
}

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

In your project gradle scripts add following lines to repositories. For Android Studio (2020.*) the repositories are in settings.gradle dependencyResolutionManagement(Gradle version 6.8 or greater). If you are using old versions of Android Studio (4.*) then the repositories will be in project level build.gradle allprojects{}.

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

Sync project with gradle files. (Android Studio -> File -> Sync Project With Gradle Files)

Quick Sample

Create CallComposite and launch it. Replace <GROUP_CALL_ID> with your group ID for your call, <DISPLAY_NAME> with your name, and <USER_ACCESS_TOKEN> with your token. For full instructions check out our quickstart or get the completed sample.

Kotlin

val communicationTokenRefreshOptions = CommunicationTokenRefreshOptions({ "<USER_ACCESS_TOKEN>" }, true)
val communicationTokenCredential = CommunicationTokenCredential(communicationTokenRefreshOptions)

val locator: CallCompositeJoinLocator = CallCompositeGroupCallLocator(UUID.fromString("<GROUP_CALL_ID>"))
val remoteOptions = CallCompositeRemoteOptions(locator, communicationTokenCredential, "<DISPLAY_NAME>")
        
val callComposite: CallComposite = CallCompositeBuilder().build()
callComposite.launch(context, remoteOptions)

Java

CommunicationTokenRefreshOptions communicationTokenRefreshOptions =
        new CommunicationTokenRefreshOptions(() -> "<USER_ACCESS_TOKEN>", true);

CommunicationTokenCredential communicationTokenCredential = 
        new CommunicationTokenCredential(communicationTokenRefreshOptions);

final CallCompositeJoinLocator locator =  new CallCompositeGroupCallLocator(UUID.fromString("<GROUP_CALL_ID>"));
final CallCompositeRemoteOptions remoteOptions =
                new CallCompositeRemoteOptions(locator, communicationTokenCredential, "<DISPLAY_NAME>");

CallComposite callComposite = new CallCompositeBuilder().build();
callComposite.launch(context, remoteOptions);

Accessibility

Previous Android API devices could perform accessibility differently comparing to the latest version. We ran through accessibility testing on previous Android API (21, 24, 27, 28) devices to detect the possible differences on accessibility performance.

API 21

When focusing on buttons, screen reader will not announce "double tap to activate".
There is no initial focus on setup screen.
The state/selected change for audio device select menu and video/mic/switch camera buttons may not be announced.
The snackbar on setup screen with error message will not be focused and announced.

API 27/28

The state/selected change for audio device select menu and video/mic/switch camera buttons may not be announced.
The snackbar on setup screen with error message may take more time to show up.
