Initializing the SDK

This document explains how to integrate the Dolby.io Communications Client SDK into your application. If you use UI components, please refer to the UXKit.

Add the Android SDK into your application

Add the public-sdk in the dependencies block of your app's build.gradle

implementation "com.voxeet.sdk:sdk:${version}"

Where version is the latest version of the SDK.

Initialize the SDK

The Android Client SDK provides the initialize method to authenticate against the service using an access token. For more information, see the section titled Initialize the SDK with secure authentication.

When the application has received the access token from the customer’s server, it can initialize the SDK with:

String url = serverURL + "/api/token";

JsonObjectRequest fetchRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
 @Override
 public void onResponse(JSONObject response) {
 VoxeetSDK.initialize(token, (refreshClosure) -> {
 // VoxeetSDK calls this closure when the token needs to be refreshed. See the next section for details.
 })
 }
 }, new Response.ErrorListener() {

 @Override
 public void onErrorResponse(VolleyError error) {
 // TODO: Handle error

 }
 }
);

// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(fetchRequest);

Refresh authentication

An access token has a limited period of validity and needs periodic refreshing. In the application, the Dolby.io Communications Client SDK invokes the callback provided to the initialize call when the access token needs to be refreshed. This callback contacts the customer’s server, which in turn calls the oauth2/token API again and returns the refreshed token, which is passed back to the Client SDK by the application.

When the application has received the refreshed access token from the customer’s server, it can pass this to the SDK with this change:

JsonObjectRequest fetchRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
 @Override
 public void onResponse(JSONObject response) {
 VoxeetSDK.initialize(token, (refreshClosure) -> {
 // VoxeetSDK calls this closure when the token needs to be refreshed.
 // Call the SDK’s refresh closure with the new token
 refreshClosure(token);
 })
 }
 }, new Response.ErrorListener() {

 @Override
 public void onErrorResponse(VolleyError error) {
 // TODO: Handle error

 }
 }
);

Open a session

// You can use cascading promises

ParticipantInfo participantInfo = new UserInfo("a name", "optional id", "optional https avatar url");

VoxeetSDK.session().open(participantInfo).then(new PromiseExec<Boolean, Object>() {
 @Override
 public void onCall(@Nullable Boolean result, @NonNull Solver<Object> solver) {
 //insert your logic
 }
}).error(error());

Close a session

VoxeetSDK.session().close().then(new PromiseExec<Boolean, Object>() {
 @Override
 public void onCall(@Nullable Boolean result, @NonNull Solver<Object> solver) {
 //insert your logic
 }
}).error(error())

Result

The Dolby.io Communications Client SDK is integrated with your application, so you have access to all SDK functionalities.

Now you can easily configure your SDK. Tutorials available in the left-side navigation panel and reference documentation guides how to do it.
