Hello Erel,
the part of the code where i find the path to the correct directorie is here. It uses the code you put somewhere on this forum.
'when we arrive at this point, the card is not found => start searching
#If Debug
Log("Watchdog => SD-card not found: start searching")
#End If
Try
'If it works, a higher version of android is used and the access to the external SD-card is limited to special folders.
'Paths will contain a list of the names of those folders
Dim ExternalFilesDirs() As Object = pGetContext.RunMethod("getExternalFilesDirs", Array(Null))
#If Debug
Log("Watchdog => method getExternalFilesDirs works: use this method to find path to files OTP")
#End If
For Each item As Object In ExternalFilesDirs
#If Debug
Log("Watchdog => test path " & item)
#End If
Try
If File.Exists(item, "CONFIG") = True Then
'card found at this location
CodeModule.RootOTP= item
CodeModule.ReadySdCard= True
LogColor("Root OTP= " & CodeModule.RootOTP, Colors.Red)
Return True
End If
Catch
CodeModule.avoidcompilerwarning_EmptyCatchBlock= 0
End Try
Next
Catch
'ignore this error because the lower versions of android do not support those methods
CodeModule.avoidcompilerwarning_EmptyCatchBlock= 0
#If Debug
Log("Watchdog => error ignored while searching SD-card: " & LastException.Message)
#End If
End Try
it produces a path as follows:
Watchdog => SD-card not found: start searching
Watchdog => method getExternalFilesDirs works: use this method to find path to files OTP
Watchdog => test path /storage/emulated/0/Android/data/otp.gcm/files
Watchdog => test path /storage/extSdCard/Android/data/otp.gcm/files
>>>>>>>> RootOTP= /storage/extSdCard/Android/data/otp.gcm/files
When i use the path for reading files, all files are there so the path as such must be correct.
When i want to write to a file on this path, it is then that the error pops up:
Private Sub WriteBlock(FileName As String, BlockNumber As Int, Block() As Byte)
'write the block
Dim Position As Int = BlockNumber * 256
Dim raf As RandomAccessFile
>>>> raf.Initialize(RootOTP, FileName, False) 'ReadOnly set to False
raf.WriteBytes(Block, 0, 256, Position)
raf.Flush
raf.Close()
End Sub
and this is what the logfile says:

One remark: a pc is used to create the folder structure and write the files on the SD-card.
It might be that android can see that and regards the folder/files as owned by another app
The problem is on a Samsung model number GT-I9505 with the software updated by Samsung (so not rooted, flashed etc.) to Android version 5.0.1
Thanks for your fast reply,
