This package offers Java bindings for the Shopify API to allow Shopify users to access the admin functionality of their accounts within 3rd party Android applications. This library was not officially created by Shopify, and though it works it is currently not being actively maintained. Developers may use the package to integrate admin functionality across articles, assets, customers, events, and more. The Shopify API uses a RESTful interface and responses are formatted in XML and JSON.
Payleven, the Square equivalent for the world outside of the US, has launched an API to complement its mobile payment device. Prior to the API, use of Payleven's mobile payment device required downloading the Payleven app (similar to Square's current model). However, the API allows developers to integrate Payleven's functionality within third party apps.
