What is the best way to show a dialog or a busy cursor for an AIR application before displaying anything pre-processing? Otherwise, the user might think that this app has crashed in 15-25 seconds, which takes it ...
I can not talk specifically for AIR, but I have written on all Flash pages, apps and widgets, I always include a preloader.
It actually loads external material.
But if you are only doing heavy calculations and are not loading any external data:
- Set the total number of "units of work", which Need to complete (Example: if you have data to process 100 rows, which are the total units of your work)
- Display an animated "Loading ..." movie clip
- Begin computing and calculating variables each time
in your loading movie clip in a TextField:
Percent = (Count / Total)% 100
