# 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.

# Theme

# Using Sumsub SDK Theme API

Starting from SDK version 1.26 it is possible to use the SDK Theme API.

// create a theme using builder SNSTheme
val customTheme = SNSTheme {
    // customize theme parameters
    colors.backgroundCommon = SNSThemeColor(resources.getColor(R.color.owl_yellow_200))
    fonts.headline1 = SNSThemeFont(Typeface.MONOSPACE, 40)
    metrics.activityIndicatorStyle = SNSThemeMetric.Size.LARGE
    // ... other parameters

    // or like so
    colors {
        backgroundNeutral = SNSThemeColor(Color.RED)
        // ... other parameters
    fonts {
        headline1 = SNSThemeFont(Typeface.MONOSPACE, 40)
        subtitle2 = SNSThemeFont(Typeface.MONOSPACE, 10)
        // ... other parameters here
    metrics {
        screenHorizontalMargin = resources.getDimension(R.dimen.sns_margin_large)
        screenHeaderAlignment = SNSThemeMetric.TextAlignment.RIGHT
        bottomSheetHandleSize = SizeF(20f, 20f)
        // ... other parameters

// provide the theme to the SDK builder
val snsSdkBuilder = SNSMobileSDK.Builder(this, apiUrl).withTheme(customTheme)
// create a theme using SNSThemeKt.newSNSTheme() method
SNSThemeHolder theme = SNSThemeKt.newSNSTheme();

// get parameter scopes
ColorsScope colorsScope = theme.getColorsScope();
MetricsScope metricsScope = theme.getMetricsScope();
FontsScope fontsScope = theme.getFontsScope();

// customize theme parameters
colorsScope.setBackgroundCommon(new SNSThemeColor(Color.RED, Color.GREEN));
fontsScope.setHeadline2(new SNSThemeFont(Typeface.SERIF, 15));
// ... other parameters

// provide the theme to the SDK builder
SNSMobileSDK.Builder builder = new SNSMobileSDK.Builder(this).withTheme(theme);

# Using Android theme

The SDK uses a material components theme for widgets. Using the SDK builder's .withTheme() method, provide a theme with the following attributes:

  • Color attributes:

    • colorPrimary: A primary color for the app, often used for the app bar and other prominent UI elements.

    • colorOnBackground: The color used for text and other content placed on top of the background color.
    • colorOnSurface: The color used for text and other content placed on top of the surface color.
