Features

• Simplified threading model: annotate your methods to ensure they'll be executed on the UI thread or on a background thread.
• Event binding: annotate methods to handle events on views, no more ugly anonymous listener classes!
• Dependency injection: inject views, extras, system services, resources, and even custom objects and let AndroidAnnotations take care of the details.
• Rest client: define a client interface with a few annotations, and AndroidAnnotations takes care of the implementation details.
• AndroidAnnotations provides those good things and even more for less than 50kb, without any runtime perf impact!
