Flow for Mobile Android SDK

📱 Sample Android App – Flow SDK Integration Demo

As part of the live coding demo, this sample Android project demonstrates how to integrate the Flow SDK into your application. It showcases the basic setup, initialisation, and usage of key features provided by the SDK.

---

🚀 Features Demonstrated

• SDK initialisation
• Basic usage of core SDK components
• Minimal UI integration example

---

📦 Requirements

• Android Studio Ladybug or newer
• Gradle 8.x
• Android SDK minSdk 21+, targetSdk 35
• Kotlin 2.2.+

---

⚙️ Getting Started

1. Clone the repo

 git clone https://github.com/checkout/checkout-android-components-google-pay-live-stream-demo-app.git

2. Sync Gradle & Build the Project

3. Add you configuration in the local.properties file

We set up the project in order to look for the following keys in you local.properties
Please use our Dashboard to create those values and add them as per the following

sandbox.components.processing_channel= {YOUR_PROCESSING_CHANNEL}
sandbox.components.secret_key= {YOUR_SECRET_KEY}
sandbox.components.public_key= {YOUR_PUBLIC_KEY}

The values will be then available as Build.Config across the project

📘 SDK Integration Walkthrough

The integration is broken down into clearly marked steps in the codebase — just look for comments like // STEP 1, // STEP 2, etc.

Here’s a quick overview of what each step does and where to find it:

Step	Description	File / Location
// STEP 1	Create the payment session	SampleViewModel.kt
// STEP 2	Create the CheckoutComponent	SampleViewModel.kt
// STEP 3	Create the configuration needed for the factory	SampleViewModel.kt
// STEP 4	Create the component factory	SampleViewModel.kt
// STEP 5	Create the component	SampleViewModel.kt
// STEP 6	Use the component in your UI	SampleViewModel.kt,SampleScreen.kt
// STEP 7	Create a GooglePayFlowCoordinator	SampleViewModel.kt,SampleActivity.kt

Each step includes inline comments explaining what’s happening and why.

💡 Pro tip: Search the codebase for STEP to jump between sections quickly.
