Android SDK - Technical Guide


This document helps developers to integrate the Cardknox Payments SDK with an Android app project using the gradle build system.

Technical Overview

  • The SDK is distributed as an .aar

  • SDK expects to be provided the androidx.cardview package externally, such as via the gradle rule implementation 'androidx.cardview:cardview:1.0.0'

  • App launch specifics:

    • AndroidManifest.xml file registers a mono.MonoRuntimeProvider ContentProvider, responsible for loading the Mono runtime on app launch

  • Supported architectures:

    • arm64-v8a

  • Package name is cardknox.payments.sdk

Getting started

To start:

  1. Add the obtained aar file to your Android Studio project, for example into the app module libs folder; and register the .aar in the app's build.gradle

  2. Provide the androidx.cardview dependency either explicitly or as a transitive dependency of some other package, such as

CardknoxPaymentsSDK aar registration
dependencies {
  implementation fileTree(dir: 'libs', include: ['Cardknox.Payments.SDK.aar'])
  // Option 1: explicitly provide the androidx.cardview dependency for the SDK
  implementation 'androidx.cardview:cardview:1.0.0'
  // Option 2: implicitly provide the androidx.cardview dependency via the google.material package
  implementation ''
