How to Build Android Widgets with .NET MAUI
Android widgets can live “inside” your MAUI app, but they still have their own rules: RemoteViews, AppWidgetProvider, intent-based interactions, and OEM quirks.
This guest post from Toine de Boer is a great reference if you want to build a widget that starts simple (static) and grows into something interactive and configurable.
Bonus: the post links to a working sample repo (Maui.WidgetExample) so you can copy/paste from something real.
