Gluon Charm Down
Gluon Charm Down is the component that addresses the integration with low-level platform APIs in an end-to-end Java Mobile solution.
Using Charm Down, you write code that access device and hardware features using a uniform, platform-independent API. At runtime, the appropriate implementation (charm-down-desktop, charm-down-android, charm-down-ios) makes sure the platform specific code is used to deliver the functionality.
Charm Down 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.
The Gluon samples are a good way to find out how Charm Down is used.
