• Add setBundle() to R in order to manually set the ResourceBundle
• Update R.get() to handle MissingResourceException by using printing "key:param1:...:paramN"

Thanks! This doesn't yet catch the case when the ResourceBundle isn't set manually and cannot be loaded automatically, the fallback is only effective if the key is actually not available.
Without testing it, I'd even assume that the attempt to call setBundle would crash on Android.
