About

Adyen Checkout is a native client for accepting payments in-app.

By using the token generated by Adyen, you don't have to deal with PCI compliance.

You can integrate with Adyen library by either:

• Importing our UI library and allowing us to take care of the token generation and data encryption.
• Integrating Adyen library SDK to have the freedom of creating your own UI model and make calls to our library.

UI implementation

Include the payment form to make your first payment.

Importing the binaries

1. In your build.gradle of the root directory add the following line:

   buildscript {
       repositories {
           ...
       }
       dependencies {
           ...
           classpath 'de.undercouch:gradle-download-task:2.1.0'
       }
   }

   This plugin will allow Gradle to download the Adyen library.

2. In your build.gradle of the app module add the following task:

   import de.undercouch.gradle.tasks.download.Download
   
   ...
   
   task downloadAdyenLibrary(type: Download) {
       src 'https://raw.githubusercontent.com/Adyen/AdyenCheckout-android/master/adyenpaysdk/adyenpaysdk-1.0.0.aar'
       src 'https://raw.githubusercontent.com/Adyen/AdyenCheckout-android/master/adyenuisdk/adyenuisdk-1.0.0.aar'
       dest('libs');
   }

   Once you run this task using ./gradlew downloadAdyenLibrary command, the adyenuisdk and adyenpaysdk .aar files will be downloaded in you libs folder.

3. Next add the following snippet in your build.gradle of the app module:

   repositories {
       flatDir {
           dirs 'libs'
       }
   }

Importing the sources

Follow these steps to edit your build.gradle and start using Adyen checkout for your Android application:

1. Run git pull https://github.com/Adyen/AdyenCheckout-android.git.

2. Copy adyenpaysdk and adyenuisdk in your application folder.

3. Add ':adyenuisdk', ':adyenpaysdk' in your settings.gradle file.

4. Copy volley-release.aar from one of the modules added above lib folder into your app lib folder.

5. Add the following code snippet to your android module insinde build.gradle"

   repositories {
       flatDir {
           dirs 'libs'
       }
   }

6. Add the following code snippet to your dependencies module insinde build.gradle:

   compile project(':adyenpaysdk')
   compile project(':adyenuisdk')

Code implementation

Add the PaymentActivity in your AndroidManifest.xml:

<activity
    android:name="adyen.com.adyenuisdk.PaymentActivity"
    android:screenOrientation="locked"/>

Next, in order to lauch PaymentActivity add the code snippet bellow on the click event on your checkout button:

CheckoutRequest checkoutRequest = new CheckoutRequest();
try {
    checkoutRequest.setBrandColor(your_brand_color);
    checkoutRequest.setBrandLogo(your_brand_logo);
    checkoutRequest.setCheckoutAmount(checkout_amount);
    checkoutRequest.setCurrency(Currency.EUR);
    checkoutRequest.setToken(your_token);
    checkoutRequest.setTestBackend(true);//default is set to false. Set it to true if you want to use Adyen's test back-end.

    Intent intent = new PaymentActivity.PaymentActivityBuilder(checkoutRequest).build(this, context);
    startActivity(intent);
} catch (CheckoutRequestException e) {
    Log.e("tag", e.getMessage(), e);
}

Make sure your Activity or Fragment implements AdyenCheckoutListener. By doing this you will also implement checkoutAuthorizedPayment(String paymentData, float amount) as well as checkoutFailedWithError(String errorMessage). The parameter paymentData of checkoutAuthorizedPayment represents the encrypted payment data that needs to be sent to the merchant server.

Check adyen.com.pay.MainActivity.java for a complete code example of a UI library implementation.

Credit Card Form UI implementation

This is a combination of the Adyen checkout UI library and the Adyen checkout SDK implementation. This type of implementation offers the merchant the option to implement our UI for the credit card form and design their own screen around the credit card form. Follow these steps to edit your build.gradle and start using Adyen checkout for your Android application:

1. Run git pull https://github.com/Adyen/AdyenCheckout-android.git.

2. Copy adyenpaysdk and adyenuisdk in your application folder.

3. Add the following code snippet to your dependencies module insinde build.gradle:

   compile project(':adyenpaysdk')
   compile project(':adyenuisdk')

Now that both the UI library and the SDK are part of your project you need to add the credit card form inside your activity or fragment xml:

<com.adyen.adyencheckout.ui.CreditCardForm
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

As you are implementing your own payment button, you need to call the following API calls to retrieve the encrypted card data, and send it to the your server.

public void initCreditCardPayment(final CardPaymentData cardPaymentData) {
    Adyen.getInstance().fetchPublickKey(new CompletionCallback() {
        @Override
        public void onSuccess(String result) {
            String ecryptedData = cardPaymentData.serialize();
            
            //Send ecryptedData to your merchant server
        }
        
        @Override
        public void onError(String message) {

        }
    });
}

Check our adyen.com.adyenuisdk.PaymentFragment.java for a complete code example of a UI library implementation.

Library implementation

Follow these steps to edit your build.gradle and start using Adyen checkout for your Android application:

1. Run git pull https://github.com/Adyen/AdyenCheckout-android.git.

2. Copy adyenpaysdk in your application folder.

3. Add the following code snippet to your dependencies module insinde build.gradle:

   compile project(':adyenpaysdk')

After including the library SDK in your Android application, implement the following API calls to retrieve the encrypted card data, and send it to your server.

public void initCreditCardPayment(final CardPaymentData cardPaymentData) {
    Adyen.getInstance().fetchPublickKey(new CompletionCallback() {
        @Override
        public void onSuccess(String result) {
            String ecryptedData = cardPaymentData.serialize();
            
            //Send ecryptedData to your merchant server
        }
        
        @Override
        public void onError(String message) {

        }
    });
}

Check our adyen.com.adyenpaysdk.Adyen.java for a complete code example of a library SDK implementation.

Merchant server
