You can use any hostId you'd like, and only need to be unique inside of your package name. (The system keys them on both the package name and the hostId combined.) > 2) It seems the only way to obtain an AppWidgetProviderInfo object for > an AppWidget is to throw the APPWIDGET_PICKER intent.

You could walk the PackageManager information yourself and figure out everyone who provides widgets, but you'll still need to launch the PICK intent explicitly. The PICK intent is special because the system is the only one we trust to bind appWidgetIds to a specific widget that the user has picked. We could totally add something like filtering or categories to the list that PICK exposes to users, but that's a topic for future releases. > 3) Also, can I pass extra data to the AppWidget's creation activity > for use when figuring out what to display? Sure, you can add any extras to the CONFIGURE intent, such as positioning information. Most widgets will probably just ignore extras, but some could take advantage of them. -- Jeff Sharkey [email protected] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
