Handling user interaction, refreshing the widget on external or inner (to the HTML content) events, handling the resizing and other events of the widget or managing more dynamic content for it and many other things are not the focus of this article, or it would become a book. The solution presented here is called introductory because to be honest there is really a lot that can be said, extended and further developed starting from the initial steps that follows in this article. Well, this article presents an introductory solution to accomplish exactly that: build an Android App Widget in HTML. ![]() One of this is surely the building of an Android App Widget which for its specific nature is particularly tricky to develop in HTML especially because the Android WebView cannot be used in an App Widget layout as by the Android specifications, and so cannot be used (at least not directly) to accomplish the task. Still, while it is possible nowaday to build apps with web technologies that with a single code base can be run at least on Android and iOS and with little additional effort also on Windows, Mac and Linux desktops thanks to the wonderful Progressive Web Application (PWA) specifications now widely adopted by almost every browser, the same cannot be said for some specific tasks that remain elusive to web technologies. Web technologies are spreading all over the world at increasing speed, feeding once again one of the oldest and all time greatest dream of all programmers of any age and places, the "write once, run anywhere" promise, many times flaunted but never completely accomplished by any tool, framework, company or tecnology so far. ![]() Checkout Cedilla on GitHub (Apache 2.0 license).
