Let's say I want to build a mobile App which others can include/integrate in their app as a separtate module. The goal is that the customers can add the functinality of my app into theirs. Since the customers have different OS/plattforms it should be plattform independent. Could i write a html5 hybrid app which is then integratable through a plugin into every existing app?
Given the fact that you want to use native features and want developers to actually integrate your plugin you likely do best by programming it natively.
