Square has launched the Register API for Android only a couple of months after releasing the API for iOS. The API allows developers to build end to end point-of-sale solutions that utilize Square's entire payment platform, or that integrate with third party infrastructure and applications.
Google has released a new version of the Android SDK, which contains the final set of APIs for Android N. Developers can now add N behaviors to their apps. Along with the APIs and SDK, Google also pushed out a fourth Android N Developer Preview. The beta operating system is ready for download.
