#### Requirements * Android 6.0 (API level 23) and above * [Android Gradle Plugin](https://developer.android.com/studio/releases/gradle-plugin) 8.5+ * [Gradle](https://gradle.org/releases/) 8.8+ * [AndroidX](https://developer.android.com/jetpack/androidx/) #### 1. Setup the server ```js $ npm install @juspay-tech/hyperswitch-node ``` Follow the Server Setup section. #### 2. Build checkout page on your app **2.1 Add the Buildscript Classpath** To start integrating the Juspay Hyperswitch SDK, add the following classpath to the `buildscript` block of your project-level `build.gradle` file: 
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "io.hyperswitch:hyperswitch-gradle-plugin:$latest_version"
    }
}
**2.2 Apply the Plugin** Add the following plugin to the `plugins` block of your app-level `build.gradle` file: ```gradle plugins { // Apply Hyperswitch Plugin id 'io.hyperswitch.plugin' } ``` **2.3 Implement the HyperInterface** Next, implement the `HyperInterface` in your Activity. This involves extending `FragmentActivity` and implementing the `HyperInterface`: ```kotlin class WidgetActivity : AppCompatActivity(), HyperInterface { // ... } ``` **2.4 Initialize Payment Configuration** Set up the SDK using your publishable key: ```kotlin private fun initialiseSDK() { // Initialize Payment Configuration PaymentConfiguration.init(applicationContext, publishKey) } ``` #### 3. Implementation Choose from list of available widgets to integrate: 1. Card Element 2. Google Pay 3. PayPal 4. Express Checkout **Final Step** Congratulations! You have successfully integrated Juspay Hyperswitch widgets into your app. This approach gives you granular control over each payment method and allows for custom UI/UX design while leveraging Juspay Hyperswitch's payment processing capabilities. #### Next step: [^1]: [Get Latest Version](https://central.sonatype.com/artifact/io.hyperswitch/hyperswitch-gradle-plugin/versions) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.hyperswitch.io/integration-guide/payment-experience/pay-then-vault/mobile/android/widgets.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
