Henrik, SCREEN_OFF is usually followed by the device entering sleep mode, so that issue pretty much takes care of itself.
Checking for the current virtual home screen, and currently active home app among several possibly installed doesn't really fit the widget programming model - it's more a push rather than pull (as it is with regular views, that are drawn on demand). I hope that home screen apps have some smarts for that (and maybe they really do). I found it very useful to implement checks for "stale" widget ids in my apps, so my code doesn't waste time updating 5-10-88 (yes, I've seen that number) widgets when there is only one on the screen. http://kmansoft.wordpress.com/2010/06/22/per-widget-options-stale-widgets Some causes of this are fixed in 2.2, but I'm keeping that code just in case. -- Kostya 2011/1/17 Henrik Lindqvist <[email protected]> > My AppWidgets are updated by a Service at user-defined intervals or > when certain intents occur.
