Proteus is meant to be a drop-in replacement for Android’s LayoutInflater; but unlike the compiled XML layouts bundled in the APK, Proteus inflates layouts at runtime. With Proteus, you can control your Apps layout from the backend (no WebViews). Forget the boilerplate code to findViewById, cast it to a TextView, and then setText(). Proteus has runtime data bindings and formatters. Plugin in your own custom views and attributes and functions to flavour proteus to your requirements. Instead of writing layouts in XML, in proteus layouts are described in JSON, which can be used to inflate native Android UI at runtime. The JSON layouts can be hosted anywhere (on the device, on servers, etc.).
