This is a guide on building a custom Social Embed Widget. For an overview of the Custom Widget UI system see Custom Widget UI.

Social Embed Widget Model

Social Embed Data(object of LiveLikeWidget class)
The Social Embed Data provides data about the Social Embed Widget such as the oembed provider url, provider name, html and many more.

The model also provides metadata about the widget such as the Date that it was created or the timeout duration set by the Producer.

Sample Social Embed Widget

class CustomSocialEmbed: ConstraintLayout {
    var socialEmbedWidgetModel: SocialEmbedWidgetModel? = null
    private lateinit var binding: CustomSocialEmbedBinding

    constructor(context: Context) : super(context) {
        init()
    }

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
        init()
    }

    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(
        context,
        attrs,
        defStyle
    ) {
        init()
    }

    private fun init() {
        binding = CustomSocialEmbedBinding.inflate(LayoutInflater.from(context), this@CustomSocialEmbed, true)
    }

    override fun onAttachedToWindow() {
        super.onAttachedToWindow()
        socialEmbedWidgetModel?.widgetData?.let { liveLikeWidget ->
            liveLikeWidget.socialEmbedItems?.get(0)?.let { oembed ->
                binding.webView.settings.javaScriptEnabled = true
                binding.webView.settings.domStorageEnabled = true


                binding.webView.loadDataWithBaseURL(
                    oembed.oEmbed.providerUrl,
                    oembed.oEmbed.html, "text/html", "utf-8", ""
