/storage/emulator/0

[Rusty]

I am running my app on an Asus 10" tablet.
I've been using the values of

File.DirRootExternal (which, until now always return /mnt/sdcard

All of a sudden, it now returns

/storage/emulated/0

This is not an emulator, it is a real device that used to return the former results until today.
Has anyone experienced this? If so, what caused it and how did you fix it?
Thanks,
Rusty

Has you device been upgraded to JellyBean?, that's how it's been reported now.

 

[Rusty]

Yes, it has, I believe it has been for a while, though I might be wrong on that.
Is this a new file structure under Jellybean or how does one handle this?
I'm expecting /mnt/sdcard ...
Thanks,
Rusty

 

[NJDude]

That's how it is now.

 

[Rusty]

Nice of them to change it...nothing like a rogue operating system, eh?
Reminds me of the old MS/DOS frontier.

Thanks for your very fast responses

It shouldn't really matter what its called as long as you access it via File.DirRootExternal'!
Although its annoying - I've experienced the same issue!

You are right.
I do access it via the file.dirrootexternal, but the OS seems like it is still in fairly early development. This is the third time they've changed this in the past 2 years...
Not a problem.

Things change from version to version.

Sorry, I do not quite get the WAY AROUND to this problem....anyone can properly say it clearly?

NOTE: I've got the same problem (as Rusty) on Asus 7" tablet.

When you are trying to use the device "root directory" as long as you:

'Do this
If File.Exists(File.DirRootExternal , ...filename) then...
'Instead of this
If File.Exists("mnt/sdcard", ...filename) then...

you will be fine, it's when you hard code it like example 2 above, you get into trouble when "they" change the name/location of the data root structure.

Hi Rusty,

I found the way to it.... first, I copied (from inserted MicroSD card) the folder of my interest (in this case, an Images) into the built in SDCARD storage. Hence, I am having a folder called "Images" in it (the SDCARD). Then, I used the following code (in bold):

imageFolder = "/mnt/sdcard/Images/"
If File.Exists(imageFolder, "") = False Then
....

(code modified from ScrollView example)


Once running the modified ScrollView code example....bingo, the images pop up into my Asus tablet screen!

Long live B4A!!!!

I would do it this way so if there are OS changes, they don't affect me:

if File.exists(file.DirRootExternal, "") = False then

This should give you the same results.
Look here for a discussion of these items.
