Thank you all, I have gotten this to work. Mark, I apologize, I didn't
quite understand what you were saying, but now I do. I was able to get
it working easily once I understood this.
You can also update the app widget from any class in your application,
like so:
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance
(context);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.main);
// Perform updates on the view
appWidgetManager.updateAppWidget(new ComponentName(context,
TheWidgetProvider.class), views);
This was probably obvious, but I didn't understand it right away. You
can call this from anywhere, assuming you have a context. Thank you
all for helping me better understand something so simple.
