Setup

Before you can add PayPal, you will need to:

1. Create, verify, and link your PayPal account in the Braintree Control Panel
2. Set up your Android SDK and obtain your client token
3. Declare a URL scheme in your AndroidManifest

Using our Drop-in UI

When using the Drop-in UI, a PayPal payment option will be shown alongside any other payment methods you've enabled.

For more details, see the Drop-in UI guide.

Using a Custom UI

You can optionally implement a custom button to start a PayPal flow.

Get the SDK

Add the following in your app-level build.gradle:

dependencies {
    implementation("com.braintreepayments.api:paypal:4.49.1")
}

Initialization

Create a BraintreeClient with a ClientTokenProvider or Tokenization Key. Construct a PayPalClient, and add a click listener to your button to initiate the PayPal flow. For a complete integration example, see the Vault or Checkout pages.

class MyActivity : AppCompatActivity() {

  private lateinit var braintreeClient: BraintreeClient
  private lateinit var payPalClient: PayPalClient

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    braintreeClient = BraintreeClient(this, ExampleClientTokenProvider())
    payPalClient = PayPalClient(this, braintreeClient)
  }

  private fun onPayPalButtonClick(view: View) {
    // The PayPalRequest type will be based on integration type (Checkout vs. Vault)  
    payPalClient.tokenizePayPalAccount(this, payPalRequest) 
  }
}

Collecting additional data

There is additional data you can gather about your customers as they complete the payment process.

Next: Choose your integration

The rest of your configuration will be determined by how you'd like to use PayPal.

• Want a checkout from your cart or product page? Use One-Time Payments.
• Need a combination of features and Pay Later offers? Use Vaulted Payments.
• Want one-click payments for repeat customers? Have a subscription model? Use Recurring Payments.
