Hi everybody,
I'm struggling with creating a directory on SD.
B4X: 
Dim lista As List=File.ListFiles("/storage/sdcard1")
For Each e In lista
    Log(e)
Next   
File.makedir("/storage/sdcard1/Android","")

lista shows correctly the content of SD card on a Android 5. I try to create the structure:
"Android/data/it.logicdata.cncfiler/files" but I didn't succede(no error, simply directory is not created)
Also creating "Android" only obtains same results.
On 4.2 is OK.
Here is the relevant code for manifest
B4X: 
AddManifestText(
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
)

Does somebody knows why?

Thank you!

I can get it also if it was not created?
I have just tested that in case I create the "supposed allowed" folder every successive creation inside of it run fine. I have also created files for sql lite and a folder in it.
Thank you...

Strange things happen here. The RuntimePermissions.GetAllSafeDirsExternal returns only one element(the SD emulated in internal memory) not the SD.
B4X: 
Dim aa As RuntimePermissions
Dim paths() As String=aa.GetallSafeDirsExternal("")
/storage/emulated/0
Dunno if the issue is in my LG X150, but using my app I'm not able to create the structure to write permanent data on SD

Ciao

Yes, Erel seems to be my case. At least I have found this problem before release. The problem is: How can I create the structure Android/data/"app id". I'm not able to create also a single level of folders. I'm testing other ways...
Thank you again!

Hi Erel, seems to be impossible to create (mkdir) the structure "/storage/sdcard1/Android/data/it.logicdata.cncfiler/files" after creation I'm able to create anything inside of it, both dirs and files. Definitly a bug or something that seems to be. I have tested QuickEdit which asks the permission to write to sd and then it can create a file on root. My app has full permissions for external storage.
