I need to load some information on Android devices and showing a progress bar immediately came to my mind. Now here's the problem:
The time it takes to get the content ready(download/decode/buffer) is not short, but not long enough to make the user navigate away. I would say around between 8~15 seconds.
Is it good practice to also show a line of text telling the user what's going on? Do the user care? Would it confuse the user? Does it make the user feel more positive while the loading commences?
What I mean by a line(single line, nothing more):
See the "Checking operating system version..." above the progress bar
As a developer, seeing the details make me happy, but I'm not sure about regular users.
TL;DR: I see this pattern used a lot with enterprise software and software installers, I'm not sure if using this pattern on a mobile app would be a good choice
EDIT: This is my first question on UX and it has more upvotes than my highest voted question on stackoverflow 2.5 years ago. Maybe I'm more suited for UX related stuff :)
