anchorGetting Started

If you are working with Android, Webex allows you to integrate secure and convenient Webex messaging and calling features in your Android apps.

The Webex Android SDK gives you the ability to customize your app and to seamlessly access powerful Webex collaboration features without ever having to leave your mobile app. Use the Android SDK to apply your own UI for customization and still use client-side API calls to embed Webex voice and video calling directly into your application. With the Webex Android SDK, you can also connect end users from your app to any Webex app/device and SIP device.

In this guide, we'll show you how to create Webex spaces, post messages, and make and receive audio/video calls.

Step 1: Integrate the Webex Android SDK

First, you need to add the following repository to your top-level build.gradle file of your project module in Android Studio.

To do this, open the Project Structure view and then open your build.gradle (Project: Your Application Name) file. Then, add mavenCentral() underneath the allprojects -> repositories code blocks, as shown below:

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://devhub.cisco.com/artifactory/webexsdk/'
        }
    }
}

Step 2: Add the Webex Android SDK Library

Now you need to include the Webex Android SDK library module as a dependency for your app.

To do this, add the following code and configuration to the dependencies block of the build.gradle (Module: app) file, as shown below:

dependencies {
   implementation('com.ciscowebex:androidsdk:2.8.0@aar', {
        transitive = true
    })
}

Step 3: Enable Multidex Support and Update Packaging Options

In order for your app code to compile correctly after integration, you will need to enable multidex support for your app.

To do this, add multiDexEnabled true to the build.gradle (Module: app) file, under defaultConfig, as shown below:

android {
    defaultConfig {
        multiDexEnabled true
    }
}

You will also need to exclude the rxjava.properties file. To do this, add these packagingOptions to the build.gradle (Module: app) file, as shown below:

packagingOptions {
    exclude 'META-INF/rxjava.properties'
}

Configure the project to use ABI Filters and APK split, as shown below:

splits {
    abi {
        enable true
        reset()
        include 'armeabi-v7a'
        universalApk false
    }
}

Now, just sync the gradle dependencies to ensure that everything integrates properly.

Keep reading for details about how to use the Webex Android SDK with your application, starting with authenticating the user, and then moving on to creating spaces and sending messages.

Step 4: App Integration and Authentication

Before your app can use Webex on behalf of another user, you will need to register a Webex Integration. Your app will either need to authenticate users via an OAuth grant flow for existing Webex users, or via a Guest Issuer token for guest users that do not have a Webex account.

Once registration is complete, you will get a Client ID and Client Secret for use with the app. These can be used to generate a token with the proper scopes.

See the examples below for creating new Webex instances for existing Webex users or for guest users who do not have a Webex account.

Example #1 - Create a new Webex instance using Webex authentication (OAuth-based):

String clientId = "YOUR_CLIENT_ID";
String clientSecret = "YOUR_CLIENT_SECRET";
String scope = "spark:all";
String redirectUri = "https://webexdemoapp.com";

OAuthWebViewAuthenticator authenticator = new OAuthWebViewAuthenticator(clientId, clientSecret, scope, redirectUri);
Webex webex = new Webex(activity.getApplication(), authenticator)
if (!authenticator.isAuthorized()) {
    authenticator.authorize(webView, new CompletionHandler<Void>() {
        @Override
        public void onComplete(Result<Void> result) {
            if (!result.isSuccessful()) {
                System.out.println("User not authorized");
            }
        }
    });
}

Example #2 - Create a new Webex instance using Guest Issuer authentication (JWT-based):

JWTAuthenticator authenticator = new JWTAuthenticator();
Webex webex = new Webex(activity.getApplication(), authenticator);
if (!authenticator.isAuthorized()) {
    authenticator.authorize(myJwt);
}

Using Webex with your App

Now that you're authenticated, you can use Webex. You can create a space, add users, and post messages using the SDK.

Create a space:

webex.spaces().create("Hello World", null, new CompletionHandler<Space>() {
    @Override
    public void onComplete(Result<Space> result) {
        if (result.isSuccessful()) {
            Space space = result.getData();
            String spaceId = space.getId();
        }
        else {
            WebexError error = result.getError();
        }
    }
});

Add users to the space:

webex.memberships().create(spaceId, null, "person@example.com", true, new CompletionHandler<Membership>() {
    @Override
    public void onComplete(Result<Membership> result) {
        if (result.isSuccessful()) {
            Membership membership = result.getData();
        }
        else {
            WebexError error = result.getError();
        }
    }
});

Post messages to the space:

webex.messages().post(spaceId, null, null, "Hello there", null, null, new CompletionHandler<Message>() {
    @Override
    public void onComplete(Result<Message> result) {
        if (result.isSuccessful()) {
            Message message = result.getData();
        }
        else {
            WebexError error = result.getError();
        }
    }
});

Webex Audio/Video Calling

This is the most significant SDK feature which enables users to make and receive audio/video calls via Webex. Calling in the SDK is very easy to use.

First, you need to register the device in order to send and receive calls:

webex.phone().register(new CompletionHandler<Void>() {
    @Override
    public void onComplete(Result<Void> result) {
        if (result.isSuccessful()) {
            // Device registered
        }
        else {
            // Device not registered, and calls will not be sent or received
        }
    }
});

Once registration is complete, you can make an outgoing call, as shown below:

webex.phone().dial("person@example.com", MediaOption.audioVideo(local, remote), new CompletionHandler<Call>() {
    @Override
    public void onComplete(Result<Call> result) {
        Call call = result.getData();
        if (call != null) {
            call.setObserver(new CallObserver() {
                @Override
                public void onRinging(Call call) {

                }

                @Override
                public void onConnected(Call call) {

                }

                @Override
                public void onDisconnected(CallDisconnectedEvent callDisconnectedEvent) {

                }

                @Override
                public void onMediaChanged(MediaChangedEvent mediaChangedEvent) {

                }
            });
        }
        else {
            WebexError error = result.getError();
        }
    }
});

These calls can be made to Webex users/devices, Telepresence systems, SIP devices, and regular telephones. If the user calls a telephone system such as an IVR, the SDK also supports DTMF transport so users can navigate IVR menus.

To send DTMF, simply invoke call.send(dtmf, completionHandler):

// Send DTMF
Call.sendDTMF(dtmfEvent, new CompletionHandler<Void>() {
    @Override
    public void onComplete(Result<Void> result){

    }
});

To receive a call:

webex.phone().setIncomingCallListener(new Phone.IncomingCallListener() {
    @Override
    public void onIncomingCall(Call call) {
        call.answer(MediaOption.audioVideo(local, remote), new CompletionHandler<Void>() {
            @Override
            public void onComplete(Result<Void> result) {
                if (result.isSuccessful()) {
                    // success
                }
                else {
                    WebexError error = result.getError();
                }
            }
        });
    }
});

anchorMigrating from the Cisco Spark Android SDK

If your project uses the Cisco Spark Android SDK, you will need to make a few changes when upgrading to the new Webex Android SDK.

1. In your project's build.gradle file, change the repository URL:

   allprojects {
       repositories {
           jcenter()
           maven {
               // url 'https://devhub.cisco.com/artifactory/sparksdk/'
               url 'https://devhub.cisco.com/artifactory/webexsdk/'
           }
       }
   }
   

2. Update the library dependency for your app:

   dependencies { 
       // compile('com.ciscospark:androidsdk:1.4.0@aar', {
       //     transitive = true
       // })
       implementation('com.ciscowebex:androidsdk:2.8.0@aar', {
           transitive = true
       })
   }
   

SDK Usage Changes

We recommend that you replace any variables names containing "spark" with "webex" in your project's code.
