Getting Started

Follow these instructions to add the Kindred Browser Plugin SDK to an existing application.

For any questions or support with your integration, or to receive your API details, please email [email protected]


The Android Mobile Browser SDK functions seamlessly across a variety of Android browsers that are supported. Below is the current list of compatible browsers. Additionally, we are committed to continually expanding compatibility by adding support for additional browsers.

  • Google Chrome
  • Microsoft Edge
  • Mozilla Firefox
  • Opera Browser
  • Duck Duck Go
  • Brave

  • Instructions contained by "[]" need to be adapted for each application.
  • Instructions contained by "{}" might change on each SDK revision.

Maven Implementation

  1. Edit the app’s module build.gradle file, and add dependencies with the latest version.
// app/build.gradle
  1. Add the file in the root of your project. This will include authentication for Maven repositories and authentication for the Kindred SDK.
    ext {

Service Configuraiton

  1. Add the Auth Settings to the defaultConfig in the module build.gradle. This is later passed down to the Kindred SDK during configuration. Make sure you apply the "":
// app/build.gradle
apply from: "../"
android {
      defaultConfig {
        buildConfigField("String", "AUTH_CLIENT_ID", "\"" + AUTH_CLIENT_ID + "\"")
        buildConfigField("String", "AUTH_CLIENT_SECRET", "\"" + AUTH_CLIENT_SECRET + "\"")
        buildConfigField("String", "AUTH_SHARED_KEY", "\"" + AUTH_SHARED_KEY + "\"")
  1. Create the Deals Accessibility service class in the app module

Note: find out more about the configuration flags below, in the section Kindred feature configuration

Note: KindredUserConfiguration is deprecated and will be removed in future versions. We suggest the use of the new functions "setUserCountry" & "setUserCurrency" from KidnredFramework.

// DealAccessibilityService.kt

import com.kindred.browser_sdk.KindredAbstractAccessibilityService
import com.kindred.browser_sdk.configuration.*

class DealsAccessibilityService : KindredAbstractAccessibilityService() {

    companion object {
        val kindredApiConfiguration = KindredApiConfiguration(
            clientID = BuildConfig.AUTH_CLIENT_ID,
            clientSecret = BuildConfig.AUTH_CLIENT_SECRET,
            sharedKey = BuildConfig.AUTH_SHARED_KEY

    override fun configureService() = KindredAccessibilityServiceConfiguration(
        api = kindredApiConfiguration,
        user = KindredUserConfiguration(
            userCurrency = "CURRENCY_CODE",
            userCountry = "COUNTRY_CODE"
        features = KindredFeaturesConfiguration(
          showEarningsConfirmationMessage = true,
        	earthMarkScoring = true,
          showCashbackLabel = true
        charity = KindredCharityConfiguration(
            charityId = "CHARITY_ID",
            charityShare = CHARITY_SHARE

    override fun onCreate() {

  1. Setting the user ID (optional)

The default configuration gives each user a unique user ID. If you wish to provide your own user ID or a unique identifier for the user for analytic purposes, you can provide the SDK with you own unique ID as follows:

// DealAccessibilityService.kt
    override fun onCreate() {

  1. Setting a custom icon (optional)

By default, the service will use a Kindred logo but it's possible to set a custom icon by providing the drawable Int in this function:

// DealAccessibilityService.kt
    override fun onCreate() {
  1. Setting an activity to return to after service activation (optional) (Min Android 7)

You can use this function to set a comeback intent. After the service is activated by the user, they will get returned to the activity if the set intent automatically:

// DealAccessibilityService.kt
    override fun onCreate() {
  1. Add the accessibility service XML file in the res/xml folder.
// accessibilityservice.xml
<accessibility-service xmlns:android=""
  1. Add permissions to the AndroidManifest.xml file
// AndroidManifest.xml
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
  1. Add accessibility service to the AndroidManifest.xml file
// AndroidManifest.xml
                <action android:name="android.accessibilityservice.AccessibilityService" />
                android:resource="@xml/accessibilityservice" />
  1. Add string values to the res/values/strings.xml (Note, you can change these values as applicable)
// strings.xml
    <string name="accessibility_service_description">By allowing the Accessibility Permission, you permit “App Name” to access data about your URLs. We do this to enable you to save money when you are shopping on your favourite brands, coupon codes will pop up at checkout, helping you to save!</string>
    <string name="accessibility_service_label">Kindred</string>
  1. Setting a custom Log prefix (optional)

By default the log message tag in the Logcat will be "kk", you can change this by providing your own custom prefix:

// DealAccessibilityService.kt
    override fun onCreate() {

Kindred Framework

KindredFramework is an object class we expose to facilitate some functionalities related to the service.


This function will return the current status of the service, a boolean indicating if the service is currently running or not.

val serviceStatus = KindredFramework.isAccessibilityServiceEnabled(context)


This function will open the accessibility settings of the service for its activation and will display a toast message with the received text.

KindredFramework.openAccessibilityServiceSettings(context, "INCLUDE YOUR TEXT HERE")

This toast message is a tiny popup at the bottom of the screen and it's centered. It will disappear after a fraction of a second.


This function will receive the context, the kindredApiConfiguration companion object that was created in the service, and a callback. It will open the wallet sign-in web page in the default browser.
The callback will receive one of three states: _SUCCEED, NO_AUTH (No authentication was detected during the process), ERROR (Something else went wrong)

 KindredFramework.openKindredWallet(this, DealsAccessibilityService.kindredApiConfiguration) {
	Log.d("kk", "$it")


This function allows you to override the country code of the initial service configuration or add one if none was specified at the service start.

KindredFramework.setUserCountry("COUNTRY_CODE", context)


This function allows you to override the currency code of the initial service configuration or add one if none was specified at the service start.

KindredFramework.setUserCurrency("CURRENCY_CODE", context)

Helper Functions


This function allows you to set a prefix for log messages, defaults to "kk"



This function allows you to control the log message output, you can also completely disable the log messages using this method. the level is set to NONE by default, meaning no log messages would be displayed.



The kindred framework automatically sends the device-id as part of the request header when making network calls, you can disable this by calling the method below.



TRANSLATIONS is an object class we expose to facilitate the customization of the strings of the popups shown by the service.
The translations can be customized from anywhere but we suggest to do it in the onCreate of the AccessibilityService class to ensure the new strings set will be used when needed.

How to use it?

class DealsAccessibilityService : KindredAbstractAccessibilityService() {
  override fun onCreate() {
    val stringMap = mapOf<String, String>(
    TRANSLATIONS.setCustomTranslations(context, stringMap)

Customizable strings

Kindred feature configuration

What is "Show Earnings" feature flag?

If you would like us to popup to the user whenever they've made any cash back or donated to a cause, you can set this feature flag on when setting up the configuration on the DealsAccessibilityService.

What is "EarthMark" feature flag?

Earthmark have developed a rating system to show how "green" retailers really are. Earthmark's rating system will now be highlighted within the Kindred technology so partners can help their users make more informed choices to shop sustainably.

Kindred Popup Customisation

you can modify the look and feel of our popups to suit your brand needs

Button Customisations

to change the color and radius of buttons

            popupAsset = PopupAsset(
                primaryColor = R.color."[color_name]",
                buttonRadius = 25

Image Resource

you can provide your own image resource to the framework for certain popups

Coupons Found
        val popupAsset = PopupAsset(
            couponFoundImage = R.drawable."[image]"

Applying Coupons

  val popupAsset = PopupAsset(
                couponFoundImage = R.drawable."[iamge]",
                applyingCouponsImage = R.drawable."[iamge]"

Best Price

val popupAsset = PopupAsset(
                couponFoundImage = R.drawable."[iamge]",
                applyingCouponsImage = R.drawable."[iamge]",
                bestPricesImage = R.drawable."[iamge]"

finally, you pass your custom image(s) to the setPopupImplementation method

            val popupAsset = PopupAsset(
                couponFoundImage = R.drawable."[iamge]",
                applyingCouponsImage = R.drawable."[iamge]",
                bestPricesImage = R.drawable."[iamge]"

            setPopupImplementation(popupAsset = popupAsset)

Alternatively, You can set custom images using web URLs, similar to the way you set image assets, call the settPopupImplementation method and then pass in a PopupAsset. Example below.

            popupAsset = PopupAsset(
                couponFoundImageUrl = "",
                bestPricesImageUrl = "[your-image-url]",
                applyingCouponsImageUrl = "[your-image-url]"

Custom popup implementation

if the customization options above doesn't satisfy your needs, you can provide a different implementation for each popup. you can do this by extending the popup class for each popup you'd like to customize and then pass your implementation to the setPopupImplementation method.

class CustomDealFoundPopup(private val context: Context) :
    DealFoundPopup(context) {
       override fun getView(
        coreSettings: CoreSettings,
        id: String?,
        cashbackMessage: String?,
        onActivate: () -> Unit,
        onActivateAll: () -> Unit,
        showEarthMarkScore: Boolean,
        earthmarkScore: Float?,
        onClose: () -> Unit
    ): View {
         //initialize your custom view
				val layoutInflater =
            context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
				val mCustomView: View = layoutInflater.inflate(R.layout."[layout_name]", null)

				return mCustomView

         override fun getWindowConfig(): WindowManager.LayoutParams {
        val windowParam = WindowManager.LayoutParams(

        windowParam.gravity = Gravity.CENTER
        windowParam.y = windowYAxisPosition

        return windowParam


to configure your own layout parameter for the WindowManager, override the getWindowConfig method and then return an instance of WindowManager.LayoutParams as done above.

Finally pass the custom implementation as a map to the setPopupImplementation method.

val customPopups = mapOf(PopupType.DEAL_FOUND to CustomDealFoundPopup(this))

 val popupAsset = PopupAsset(
                couponFoundImage = R.drawable."[iamge]",
                applyingCouponsImage = R.drawable."[iamge]",
                bestPricesImage = R.drawable."[iamge]"

setPopupImplementation(customPopups, popupAsset = popupAsset)

below is the list of customizable popups, each implementation must be passed with a valid map key and a popup class that extends the default kindred implementation.
