Make sure that ComponentName you use to get AppWidgetManager matches the widget provider in the manifest. If it doesn't, you'll get an empty list (ids.length = 0, the loop won't execute).
Not sure what you mean by "which widget coming". -- Kostya Vasilyev -- http://kmansoft.wordpress.com 21.09.2010 11:56 пользователь "Jerome Deng" <deng.jer...@gmail.com> написал: Hi guys, I have searched many topics about AppWidgetManager.getAppWidgetIds(). But I don't get any compellent answers. In my code, I first get all widget ids by AppWidgetManager.getAppWidgetIds(provider), and then do a for loop as below: for (int id : ids) {...} However, I see the for loop never executed. And if I call ids.length, the sentence never executed yet. Some people said getAppWidgetIds() can not return the right id set, that is because the some widgets were deleted but their ids are still there. My target is to know how many widgets are created by the specified widget provider, so I think getAppWidgetIds() can meet this. But it fails now. I think getAppWidgetIds() has something wrong, and the widget framework should fix this. Also, in widget provider, if it can distinguish which widget instance is coming, that means the current widget id can be passed in, then all things will be better. Why not do this in widget framework? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
