Android, Android Apps

Are you planning to sell products or services through your Android app? If yes, then it’s time to integrate a payment gateway into your app. A payment gateway is a service that allows you to securely accept payments from customers using credit cards, debit cards, or other electronic payment methods.

Here’s how you can use a payment gateway in an Android app:

Step 1: Choose the Payment Gateway

The first step is to choose a reliable and secure payment gateway that suits your business needs. Some popular payment gateways for Android apps include PayPal, Stripe, and Braintree. Research the features and pricing of each one before making a decision.

Step 2: Set up the Payment Gateway Account

Once you have selected a payment gateway, create an account with them. Follow their instructions to set up your account and provide all necessary information such as business name, bank details, and tax information.

Step 3: Integrate the Payment Gateway SDK

Most payment gateways provide SDKs (Software Development Kits) that enable easy integration with Android apps. Download the relevant SDK and follow the instructions provided by the payment gateway to integrate it into your app.

Step 3.1: Add Permissions in Manifest File

Before integrating the SDK into your app, make sure to add necessary permissions in the manifest file such as internet permission.

<uses-permission android:name=”android.permission.INTERNET” />

Step 3.2: Add Dependencies in Build.Gradle File

Add dependencies for the payment gateway SDK in your build.gradle file.

      implementation ‘com.PayPal.sdk:paypal-android-sdk:X.Y.Z’
      implementation ‘com.stripe:stripe-android:X.braintreepayments.api:braintree:X.Z’

Step 3.3: Initialize Payment Gateway

Initialize the payment gateway in your app by calling the relevant methods provided by the SDK. For example, to initialize PayPal, call:

PayPalConfiguration config = new PayPalConfiguration()

Intent intent = new Intent(this, PayPalService.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);

Step 4: Create Payment UI

Now that your payment gateway is integrated into your app, it’s time to create a UI for customers to make payments. You can use various UI elements such as buttons, text fields, and images to create an intuitive and user-friendly payment screen.

Step 5: Process Payment

When a customer makes a payment on your app, the payment gateway processes the transaction and sends you the payment amount minus any fees charged by the gateway. Make sure to handle errors and exceptions that may occur during this process.


In conclusion, integrating a payment gateway into an Android app is essential for any business that wants to sell products or services online. By following these steps and using a reliable payment gateway provider, you can provide a safe and secure payment experience for your customers.
