Gluon Attach

Gluon Attach is the component that addresses the integration with low-level platform APIs in an end-to-end Java Mobile solution.

Attach provides an uniform, platform-independent API to access device and hardware features. At runtime, the appropriate implementation (attach:desktop, attach:android, attach:ios) makes sure the platform specific code is used to deliver the functionality.

Attach is open source, and it is freely licensed under the GPL license. Gluon can provide custom consultancy and training, commercial licenses, and open source commercial support, including daily and monthly releases.

Getting started

The best way to get started with Gluon Attach is using the Gluon Client Maven archetype from your IDE and creating a Gluon Mobile project.

The Gluon Client samples are a good way to find out how Attach is used.

See the documentation on how to add Attach with the Client Plugin.
