According to paypal's documentation you can pay orders and something like that but I don't know if it's possible to send this kind of request using Android SDK (link below):
curl -v -X POST https://api.sandbox.paypal.com/v1/checkout/orders \
-H "Content-Type: application/json" \
-H "Authorization: Bearer Access-Token" \
-H "PayPal-Partner-Attribution-Id: EXAMPLE_MP" \
-d '{

}
],

}'
Ps. It seems like getStuffToBuy() (line 83) could make this request but I'm not really sure if it's possible to make it
purchase_units: [
{
reference_id: another field,
description: 'Hello World',
amount: {
currency_code: 'MXN',
value: "100.00"
}
}

Android SDK:
PayPal's Documentation:
https://developer.paypal.com/docs/api/orders/v1/
Thanks a lot!
That Android SDK is deprecated and will be end of life [December 2020]
If you want a native SDK for processing PayPal payments, use Express Checkout via the Braintree SDK
For authentication, use a sandbox access token from the bottom of https://www.paypal.com/signin?intent=developer&returnUri=https%3A%2F%2Fdeveloper.paypal.com%2Fdeveloper%2Fapplications on your server, and return a client token to your client. (production access token, https://www.paypal.com/api )
Do not create a Braintree gateway account, nor use gateway credentials from braintreegateway.com . Do not use a tokenization key.
Native Checkout is now available in some countries, notably US and Europe: https://developer.paypal.com/docs/business/native-checkout/
For non-native payments, the orders v1 documentation you linked to should also not be used. Use orders v2, https://developer.paypal.com/docs/checkout/reference/server-integration/
