DirDefaulExternal error

[laviniut]

I use some code to save the files. All is ok on my Galaxy S2 phone, also on AVD with android 4.1.2
But when i test it on AVD with android 2.3.3 and 3.1, give me an error.
The code i use:

Dim PadDir As String                            : PadDir = File.DirDefaultExternal & "/DictationFiles"
Dim PadFileName As String
...
If FirstTime AND File.Exists(PadDir, "*.*") = False Then
        File.MakeDir(File.DirDefaultExternal, "DictationFiles")
       
    End If
...
File.WriteString(PadDir, PadFileName, EditPad.text)

So, is File.DirDefaultExternal functional only after android 4 ?
And how can i save the files in android 2 and 3 ?

It should still work.
Where do you set PadFileName?
What error do you get?

 

[laviniut]

I set PadFileName after a dialog, like this:

PadFileName=fd.ChosenName & ".txt"

But everything is ok and all application works fine in my Galaxy S2 phone with android 4.1.2
and now i need to test application in other devices.
the error i get in android 2.3.3 and 3.1 in AVD is:

Are you sure you created an sdcard when configuring the emulator?

Also try this code instead:

If File.IsDirectory(File.DirDefaultExternal, "DictationFiles") = False Then
     File.MakeDir(File.DirDefaultExternal, "DictationFiles")
End If

I search in AVD 2.3.3 and there is no such a path: /mnt/sdcard/Android/data
only /mnt/sdcard
so there is the problem. with path created by
File.DirDefaultExternal
But how can i solve the problem with different android version ?

 

[thedesolatesoul]

did you try my code?

 

[laviniut]

Yes and same error.

File.DirDefaultExternal works with all versions.

On the emulator you should make sure that it is configured with a sd card.

Can you post the full code? I don't see how is FileDialog related to the code in the first post.

You should also replace this line:

Dim PadDir AsString : PadDir = File.DirDefaultExternal & "/DictationFiles"

With:

Dim PadDir As PadDir = File.Combine(File.DirDefaultExternal, "DictationFiles")

My mistake. Because i was in a hurry to test my first final application on different devices, i omitted to set sdcard in AVD.
Now I created a new AVD and is working. Thank you.
