Hi James, thanks for sharing your discoveries about this. Indeed, that was an strange decision from the Android team to provide ranges. I wonder why the launcher couldn't report *actual* width and height occupied by a widget.
By the way, I was going to answer your question before with this SO link (perhaps it helps a bit more): http://stackoverflow.com/questions/17138191/android-widget-resizing/19670267#19670267 El martes, 30 de diciembre de 2014 23:14:11 UTC-3, Dusk Jockeys Android Apps escribió: > > Ok, answering my own question. :) > > The anomaly is due to landscape.
