This is a developers' guide for setting up a LiveLike SDK configuration for native Android apps. We will take you through the basic technical steps for configuration and show you how to send your first widgets and chat messages. We will also provide detailed samples and instructions for a complete LiveLike integration.


This feature enables you to publish spoiler-free content with the Engagement SDK. When enabled, all published content from the CMS and chat messages will be synced with the live video (we don't currently support VOD). To enable Sync you will need to provide a value that represents the date/time of your media player's current playback position.

To enable sync include a method to the createSession that returns the current live timecode.

val session = sdk.createContentSession("", object :EngagementSDK.TimecodeGetter{
            override fun getTimecode(): EpochTime {
                return EpochTime(player.bufferedPosition)
LiveLikeContentSession session = engagementSDK.createContentSession("< program-id>", new EngagementSDK.TimecodeGetter() {
      public EpochTime getTimecode() {
        return new EpochTime(player.getEpochTime());

How to use the plugin for easy video-sync


  • HLS Streams
  • Include the Program-Date-Time information in the manifest
  • Have access to the Exoplayer instance in code

Add the following to your build.gradle to install the EngagementSDK Exoplayer plugin

implementation 'org.bitbucket.livelike.livelike-android-sdk:pluginexoplayer:master-SNAPSHOT'

When the Session is initialized you can now pass your Exoplayer instance directly and get your HLS stream synchronized with widgets and chat. The plugin will get the timecode from the Program-date-time tags included in your manifest.

val session = sdk.createExoplayerSession(
            object : PlayerProvider {
                override fun get(): SimpleExoPlayer? {
                    return getPlayer()
            "< program-id>"
import static com.livelike.livelikepreintegrators.ExoplayerPreintegratorKt.createExoplayerSession;

ContentSession session = createExoplayerSession(engagementSDK, () -> getPlayerInstance(), "< program-id>");

Pausing Content Sessions

Content Sessions can be paused to temporarily ignore all incoming Widgets and Chat messages until resumed. This can be useful if you need to display an advertisement without overlay from the Engagement SDK, as an example.




Customize Your Theme

Our Engagement SDK allows you to customize fonts, colors, corner radii, padding, margins and spacing to conform to your style guide. The snippets below show chat corner radii and chat background colors, as well as widget corner radii and widget background colors as sample customizations.

To get started, create a theme object, adjust the relevant properties, and apply that object to your WidgetViewController and ChatViewController. For the full list of customizable properties see the API Reference.

The same widget with different themes:


On Android, you can override the default values of colors, fonts and dimensions in the values folder of the sdk. The customizable variables and their functions are listed below:

Colors Customization:

You can override the color values by setting your own. The default values for the SDK are listed in the colors.xml resource file.

These control the gradient colors of the title. You can set them to be the same to get a single solid color title background.
  • livelike_default_title_gradient_left
  • livelike_default_title_gradient_right

Image Option: These control the image option background gradient colors.

Just like the widgets, chat component is also customizable through overriding the default values provided in the dimens/colors/attrs xml files with values in xml files in the integrating application. The variables available for customization are listed below:

The chat view is designed to fill the parent view. So its height and width can be controlled directly by the integrator by controlling the height and width of the view provided by them.
