What you do, is make sure that every time your code pushes a RemoteViews object into the home application for your widget, it's complete in all respects: - Has image resource ids; - Has text stings; - Has pending intents. Don't do "incremental" widget updates, like you would do with a regular activity - don't set the intents first, then the images, then the text reflecting current information. The home app runs as a separate process, and its state can get out-of-step with your widget receiver. When it does, the only thing it has for re-creating your widget is your most recent RemoteViews object. If it's complete, and has all the parts, everything will work just fine. If it only has the most recent text or image change, the earlier updates which had the intents will be lost. http://kmansoft.wordpress.com/2010/05/23/widgets-and-orientation-changes/ -- Kostya > Thanks > > On Jan 14, 1:28 am, Kostya Vasilyev <kmans...@gmail.com> wrote: > > Each and every update you push to the wigdget with RemoteViews has to > have > > complete widget state, including all images, text, and pending intents. > > > > There is no onUpdate on configuration changes.
