# Customization

# Support Items

Support items define the ways in which your users will be prompted to contact you on the Support screen. By default, the SDK uses the following item:

private val DEFAULT_SUPPORT_ITEM = SNSSupportItem(
    "Support Email Title", // item title
    "Support Email Description", // item subtitle
    SNSSupportItem.Type.Email, // item type
    "[email protected]", // your support email from the dashboard
    null, // or provide your custom drawable
    SNSIconHandler.SNSCommonIcons.MAIL.imageName // resolve drawable using icon handler
SNSSupportItem defaultItem = new SNSSupportItem(
    "Support Email Title",
    "Support Email Description",
    "[email protected]",

if you want to change the support items you should create a new list:

val snsSdkBuilder = SNSMobileSDK.Builder(this, apiUrl).withSupportItems(listOf(DEFAULT_SUPPORT_ITEM))
SNSMobileSDK.Builder builder = new SNSMobileSDK.Builder(this)

Each item must have a mandatory title, icon, subtitle, type and value. onClick listener is optional. By default, the SDK handles clicks if a support item were an email or a url, but if you want to change this behavior you can implement your own onClick listener and handle it by yourself. For example:

val supportItems = listOf(SNSSupportItem(
    "Google item title",
    "Google item description",
    "[email protected]",
    onClick = { item ->
        // to do something

val snsSdkBuilder = SNSMobileSDK.Builder(this, apiUrl).withSupportItems(supportItems)
SNSSupportItem defaultItem = new SNSSupportItem(
    "Support Email Title",
    "Support Email Description",
    "[email protected]",
    snsSupportItem -> {
        return null;

The support item can be one of three types:

enum class Type {

If, for some reason, you wish to use Type.Custom, please make sure that you have implemented the onClick listener.
