In an activity it's (usually) easy to get the Context.
What if I am working with a home widget class? These are classes that extends AppWidgetProvider, which don't contain a Context!

Common Issues with Android App Widgets There are cases when errors appear when using widgets: they often disappear from your home screen, freeze, or simply don't load. If you could not add a widget, most likely there is not enough space on your home screen.
– Context is a link to the location of a widget in the tree structure of widgets. – Context can belong to only one widget. – If a widget has child widgets, then the context of the parent widget becomes the parent context for the contexts of direct child elements.
There are, in general, four types of widgets: information widgets, collection widgets, control widgets, and hybrid widgets.
An instance of Context is passed to all the methods in AppWidgetProvider for you to use.
