Android Question No such file or directory. File.DirDefaultExternal not exists.

[netsistemas]

I change manifest, from sdk 4 to 5 and targetsdk 14 to 26


and now the file.dirdefaultexternal is not create automatic.

File.ExternalWritable return TRUE.

Import: This effect ONLY suceded on some phones

I can not write (or read) files in this directory because is not present (not exist).
If i create this directory manual, all is ok
In this link say that this directory are create automatic, but no.

File.DirDefaultExternal
The default folder for your application in the SD card.
The folder is: <storage card>/Android/data/<package>/files/
It will be created if required.

But no.

This is my manifest:
'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="26"/>

AddManifestText( <permission

Did you try runtime permission like this:

Private rp As RuntimePermissions
Private FilePath as string
    If File.ExternalWritable Then FilePath = rp.GetSafeDirDefaultExternal("") Else FilePath = File.DirInternal

 

[netsistemas]

thanks. Perfect.


In old version (i think previous to 4.4) you can use this:
File.DirDefaultExternal and ADD permision in manifest
but,
in new versión is not necessary add permision and use rp.GetSafeDirDefaultExternal("")

and use you code (rp.GetSafeDirDefaultExternal instead of file.DirDefaultExternal)

in new versión is not necessary add permision and use rp.GetSafeDirDefaultExternal("")

Not exactly true. You should see the runtime permissions tutorial.
