问题 Hallo, I am writing a widget, but am unsure what size bitmap to use as a background for each screen resolution/density.

It does not update the first time I tell it to, but it does update the second and third and every time afterwards. I'll really really appreciate if someone would take a look at my code Thank you very much Config class: public class WidgetConfig extends

问题 I have a problem very similar to those that have been asked before, but not exactly the same. References: 1, 2, 3, 4 I have coded up a minimal Android widget, and the APPWIDGET_DELETED and APPWIDGET_DISABLED are never being received. In references 1 and 2 above, the solution presented is to implement onReceive and explicitly look for those intents. However, I inserted a log call in onReceive , and can confirm that neither of those intents are ever appearing, though APPWIDGET_UPDATE and
