Mobile Payments Library Developer Guide and Reference – Android OS Edition July 2011 5
Preface
The PayPal Mobile Payments library provides secure, extensible, and scalable PayPal payment
functionality to the Android platform.
Purpose
The PayPal Mobile Payments Library provides an easy way for you to integrate payments into
your Android applications. You can download the library from X.com and include it in your
application. With the library, you need only a few lines of code to integrate the payments library
with your application.
When a buyer makes a payment, the library controls the checkout experience – logging in,
reviewing, and completing the payment. After buyers complete their payments, the library returns
the buyer to your application.
Scope
This document describes how to integrate the PayPal Mobile Payments Library with your
application. You must create and provide your build to PayPal so PayPal can review your
application before it is approved to accept payments via the library. The approval process is
described later in the document.
OS and Hardware Support
The PayPal Mobile Payments Library supports Android OS 1.5 and higher. All Android devices
are supported.
