This demo application also contains instructions on how to set up Beagle and how to implement the various features that are being showcased. You should definitely consider giving it a try if you're interested in using the library in your projects.

The app, just like the library itself is 100% free and open-source. Check it out on GitHub: https://github.com/pandulapeter/beagle
