Unable to create directory

johnb4a · Nov 22, 2012

Hi,

I am trying to make a directory and copy a file. but it is giving me an error.

java.io.filenotfoundexception:/storage/sdcard0/appfiles/Share.txt: open failed: ENOENT (NO SUCH FILE OR DIRECTORY).

I have added the Share.txt file inside files folder.

below is my sample code.

Any one please help me.

'Activity module
Sub Process_Globals
Dim Dir As String : Dir = File.DirRootExternal & "/appfiles"
End Sub

Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
If FirstTime AND File.Exists(Dir, "*.*") = False Then
File.MakeDir(File.DirRootExternal, "appfiles")
If File.Exists(Dir, "Share.txt") = False Then
File.Copy(File.DirAssets, "Share.txt", Dir, "Share.txt")
End If
End If

File.WriteString(File.DirRootExternal, "Share.txt", "Some text")

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Shouldn't this line

B4X:

File.WriteString(File.DirRootExternal, "Share.txt", "Some text")

be

B4X:

File.WriteString(Dir, "Share.txt", "Some text")

Best regards.

Hi Klaus,

You should add the file in the IDE Files Tab in the lower right corner with Add File.

Best regards.

Hi,

I did add the file in the IDE Files Tab. Still the same error.

In what line do you get the error ?
I tested your code on my Nexus One and it works.

Are you sure that your File.DirRootExternal is writable File.ExternalWritable ?

Best regards.

Hi,

How can i check that if File.DirRootExternal is writable?

i tried in both samsung S3 and AVD. Both giving error. i dont know what is the problem.

klaus · Nov 22, 2012

Example :

B4X:

If File.ExternalWritable = True Then TargetDir = File.DirDefaultExternal Else TargetDir = File.DirInternal

Best regards.

hi,

it is possible the /storage/sdcard0 to be write lock and you can read only the files.
Download from google play the Fx explorer and then goto to /storage/sdcard0 to make a folder
If it make the folder then you have read/write permissions
if you see the message that no permission to write then from Fx goto down to options and add the fx root (it is free addon) with this you will change the permissions to sdcard0 >> w/r

If your device have an internal sdcard then the external is locked for write by the google android and must change the permissions to w/r
