Processing of interest expression point of the users

User Interest Listener

When using GfpAdLoader, link the callback that informs when the user expressed interest (1-second exposure with 100% of the ad section by SDK definition) and when the interest disappeared (exposure of 0% or less of the ad section by SDK definition). The usage method is as follows.

Kotlin

val adLoader = GfpAdLoader.Builder(context, adParam)
    .withUserShowInterestListener { showInterest ->
        if (showInterest) {
            // ad view exposed 100% and 1 sec duration.
            // ex) change a cta button color
        } else {
            // ad view exposed 0% (hide)
            // ex) restore a cta button color
        }
    }
    .build()

Java

GfpAdLoader adLoader = new GfpAdLoader.Builder(context, adParam)
        .withUserShowInterestListener(showInterest -> {
            if (showInterest) {
                // ad view exposed 100% and 1 sec duration.
            // ex) change a cta button color
            } else {
                // ad view exposed 0% (hide)
            // ex) restore a cta button color
            }
        })
        .build();
