This repository contains various sample applications for the PayPal Checkout SDK for Android. If you have questions, comments, or ideas related to the Android Checkout SDK or the sample apps please create a new issue if one related to your question does not already exist.

Android Version Requirement

The SDK will work with apps that have a minimum version of 21. However, to launch the PayPal flow, a check for Android 23 or higher must be done.

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        PayPalCheckout.setConfig(...)
    } else {
        Toast.makeText(this, "Checkout SDK only available for API 23+", Toast.LENGTH_SHORT).show()
    }

    ...

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        PayPalCheckout.startCheckout(...)
    } else {
        Toast.makeText(this, "Checkout SDK only available for API 23+", Toast.LENGTH_SHORT).show()
    }

Sample App Preparation

The sample project is intended to be as hands off as possible. With that in mind, there are only two values which are required to this sample app and they include:

1. An app client ID. This is used by the CheckoutConfig and ensures your application can authorize customers to place orders.
2. A corresponding app secret. This is required for generating payment tokens. This is not required for your own implementation of the PayPal Checkout SDK and is only used to illustrate how you could generate tokens for customer orders with a backend system.
3. Setting a return URL.

Please reference our developer documentation overview to learn about how to create a new PayPal application as well as how to find those details. At this time, the SDK is in limited release so please be sure to follow all of the steps outlined. Once you have the credentials available you will want to add them to QuickStartConstants.kt.

// QuickStartConstants.kt
const val PAYPAL_CLIENT_ID = "YOUR-CLIENT-ID-HERE"
const val PAYPAL_SECRET = "ONLY-FOR-QUICKSTART-DO-NOT-INCLUDE-SECRET-IN-CLIENT-SIDE-APPLICATIONS"

Setting a Return URL

A return URL is required for redirecting users back to the sample app after authenticating. For more details on setting a return URL please see our developer documentation, however instead of setting the Live App Settings you want to ensure you are setting your Sandbox App Settings. The return URL you should use is com.paypal.checkoutsamples://paypalpay.
