Android 15 Beta 2: Improvements to widget previews in the widget list.

Before Android 15, the only way to provide widget picker previews was to specify a static image or layout resource. These previews often differ significantly from the look of the actual widget when it is placed on the home screen.

Also, static resources can't be created with Jetpack Glance, so a Glance developer had to screenshot their widget or create an XML layout to have a widget preview.

Android 15 adds support for generated previews. This means that app widget providers can generate RemoteViews to use as the picker preview, instead of a static resource.
