I am having the same problems of white screen before it loads. Come on ST2 team PLEASE see to this fix asap. Spent the last day looking for solutions cant show my client and our rent depends on it.
Found a hack using override technique..but its not prety the white screen still shows but not for as long http://davehiren.blogspot.com/2012/0...or-sencha.html
Out of curiosity can this be solved using HTML5 localstorage?
Did some extra research:
Seems like the startupimage is also not working when packaging the app with PhoneGap. Also the standard command line rendered project that has default startupimages set, doesn't work. In all cases no startup image is loaded.
Thank you for the input. I will have a look at it and hope we can use something of it. We do not use Phonegap for packaging, but use sencha touch for packaging.
The startupImage property is only used when an app is bookmarked to the home screen on an iOS device through a website(docs here). It does not set the startup image if you are packaging the app using the command line tools, Architect, or other third party software such as Phonegap.
