Android PayPal Java and XML Script Code

To integrate PayPal Checkout in an Android app, you’ll need:

1. A PayPal Developer account.
2. A server/backend to create and capture orders (recommended by PayPal).
3. The PayPal Android SDK or Checkout SDK.

1. Add PayPal Dependency

In your app-level build.gradle:

dependencies {
    implementation 'com.paypal.checkout:android-sdk:1.3.0'
}

Add Maven Central if needed:

repositories {
    mavenCentral()
}

2. XML Layout

activity_payment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Pay with PayPal"
        android:textSize="24sp" />

    <Button
        android:id="@+id/btnPayPal"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:text="Pay with PayPal"
        android:layout_marginTop="20dp"/>
</LinearLayout>

3. Java Activity

PaymentActivity.java

package com.example.paypalapp;

import android.os.Bundle;
import android.widget.Button;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

import com.paypal.checkout.PayPalCheckout;
import com.paypal.checkout.config.CheckoutConfig;
import com.paypal.checkout.config.Environment;
import com.paypal.checkout.createorder.CreateOrder;
import com.paypal.checkout.createorder.CreateOrderActions;
import com.paypal.checkout.createorder.CurrencyCode;
import com.paypal.checkout.createorder.OrderIntent;
import com.paypal.checkout.order.Amount;
import com.paypal.checkout.order.AppContext;
import com.paypal.checkout.order.Order;
import com.paypal.checkout.order.PurchaseUnit;
import com.paypal.checkout.order.CaptureOrderResult;
import com.paypal.checkout.approve.OnApprove;
import com.paypal.checkout.approve.Approval;

import java.util.Collections;

public class PaymentActivity extends AppCompatActivity {

    private static final String CLIENT_ID =
            "YOUR_PAYPAL_CLIENT_ID";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_payment);

        CheckoutConfig config = new CheckoutConfig(
                getApplication(),
                CLIENT_ID,
                Environment.SANDBOX,
                "com.example.paypalapp://paypalpay"
        );

        PayPalCheckout.setConfig(config);

        Button btnPayPal = findViewById(R.id.btnPayPal);

        btnPayPal.setOnClickListener(v -> {

            PayPalCheckout.startCheckout(
                createOrderActions -> {

                    Order order = new Order(
                            OrderIntent.CAPTURE,
                            new AppContext.Builder()
                                    .userAction(AppContext.UserAction.PAY_NOW)
                                    .build(),
                            Collections.singletonList(
                                    new PurchaseUnit.Builder()
                                            .amount(
                                                    new Amount.Builder()
                                                            .currencyCode(CurrencyCode.USD)
                                                            .value("10.00")
                                                            .build()
                                            )
                                            .build()
                            )
                    );

                    createOrderActions.create(order, orderId -> {});
                }
            );
        });
    }
}

AndroidManifest.xml

<application
    ...>

    <activity android:name=".PaymentActivity"/>

</application>

Quick Android Studio Setup

7. Run the app on a device or emulator.
8. Tap Pay with PayPal and log in using a PayPal Sandbox test account.

Important

PayPal’s Android integration changes over time, and current production integrations typically require a backend server to securely create and capture orders. Before deploying, consult the latest official documentation:
