If you are talking about home screen AppWidgets, then yes it is possible. The place to get started is:
http://developer.android.com/guide/topics/appwidgets/index.html Then have a look at some examples: http://www.helloandroid.com/tutorials/days-xmas-widget-tutorial http://nm-blog.sanid.com/2009/07/android-hellowidget-tutorial/ Basically as long as your AppWidgetProvider is part of the same package and also declared in same Manifest of your main appilication, then it has access to the same classes and can share its data. I dont know if you can check whether an AppWidget is currently visible, i.e. on the current pane of your Home Screen (e.g. because you have 3 on vanilla android, 7 on HTC Sense, but it can certainly know whether you have your AppWidget(s) active on at least one of your panes. Your widget can be updated directly by your application or via a custom timer, or via the frameworks automatically scheduled updates. And your widget can send info to your main application, e.g. process a click to start the application, or access its data. It's an interesting topic, good luck!
