Top Android Credit Card Libraries.

Introduction:​

In the modern era, digital payment methods have become increasingly popular, and credit card payments are one of the most common forms of online transactions. To integrate credit card processing into your Android application, you can rely on various libraries that provide robust features and simplify the implementation process. In this tutorial, we will explore some of the top Android credit card libraries, discuss their features, and provide step-by-step instructions for installation. We will also include code usage examples using Kotlin or Java where applicable.

1. Stripe:​

Stripe is a widely used payment processing platform that offers a comprehensive set of features for handling credit card payments. It provides support for various payment methods and has an extensive set of APIs. Follow these steps to integrate Stripe into your Android application:

Step 1: Add the Stripe dependency to your project's build.gradle file:

dependencies {
    implementation 'com.stripe:stripe-android:14.1.0'
}

Step 2: Initialize the Stripe instance in your application's initialization code:

import com.stripe.android.PaymentConfiguration

PaymentConfiguration.init(context, "YOUR_PUBLISHABLE_KEY")

Step 3: Create a PaymentIntent on your server and retrieve the client secret.

Step 4: Collect payment details from the user and create a PaymentMethod:

import com.stripe.android.model.Card
import com.stripe.android.model.PaymentMethodCreateParams

val card = Card.create("4242424242424242", 12, 2025, "123")
val paymentMethodParams = PaymentMethodCreateParams.create(card.toPaymentMethodParamsCard())

Step 5: Confirm the PaymentIntent using the PaymentMethod:

import com.stripe.android.Stripe
import com.stripe.android.model.ConfirmPaymentIntentParams

val stripe = Stripe(context, "YOUR_PUBLISHABLE_KEY")
val confirmParams = ConfirmPaymentIntentParams.createWithPaymentMethod(paymentMethodParams, "CLIENT_SECRET")
stripe.confirmPayment(this, confirmParams)

2. Braintree:​

Braintree is a popular payment gateway that offers a secure and simple way to process credit card payments. It supports multiple payment methods and provides customizable UI components. Here's how you can integrate Braintree into your Android application:

Step 1: Add the Braintree dependency to your project's build.gradle file:

dependencies {
    implementation 'com.braintreepayments.api:drop-in:5.11.0'
}

Step 2: Initialize the Braintree client in your application's initialization code:

import com.braintreepayments.api.BraintreeClient

val braintreeClient = BraintreeClient.newInstance(context, "YOUR_TOKENIZATION_KEY")

Step 3: Create a Drop-In UI for collecting payment details:

import com.braintreepayments.api.dropin.DropInRequest

val dropInRequest = DropInRequest()
    .clientToken("CLIENT_TOKEN")
startActivityForResult(dropInRequest.getIntent(context), DROP_IN_REQUEST_CODE)

Step 4: Handle the result in your activity's onActivityResult method:

import com.braintreepayments.api.dropin.DropInResult

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == DROP_IN_REQUEST_CODE) {
        val result = data?.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT)
        // Handle the payment result
    }
}

3. PayU:​

PayU is a popular payment gateway in India that allows you to process credit card payments seamlessly. It provides various payment options and supports multiple currencies. Follow these steps to integrate PayU into your Android application:

Step 1: Add the PayU dependency to your project's build.gradle file:

dependencies {
    implementation 'com.payu.custombrowser:payu-custom-browser:8.3.3'
}

Step 2: Set up the PayU environment and initialize the payment process:

import com.payu.india.Payu.Payu
import com.payu.india.Interfaces.PaymentRelatedDetailsListener
import com.payu.india.Model.PaymentParams

Payu.setInstance(context)
val paymentParams = PaymentParams()
paymentParams.amount = "10.0"
// Set other payment parameters

Step 3: Start the payment process by calling the PayU API:

Payu.startPaymentProcess(context, paymentParams, object : PaymentRelatedDetailsListener {
    override fun onPaymentSuccess(payuResponse: PayuResponse) {
        // Handle successful payment
    }

    override fun onPaymentFailure(payuResponse: PayuResponse) {
        // Handle payment failure
    }
})
