[WM24 android 8] permission denied write external storage

Hi,

when I try write to external storage , I keep having permission denied . internal storage no problem

IF SysStatusExternalStorage(2) = sseAvailable THEN
IF fCreate( CompleteDir(SysDirExternalStorage(2,ssePublicPhoto)) + "myFile.txt") = -1 THEN
error(ErrorInfo(errFullDetails))
END
END


I have added write external storage permission and on runtime I also allow it but it's not working.

am I missing something ?

Never mind I found why. change ssePublicPhoto to sseAppPhoto then work.

SysRemovableExternalStorage (Function)
From Android 4.4 (KitKat), if the external storage space corresponds to moveable memory (SDCard), the applications can create, modify or delete files in their own directory only (directories corresponding to the sseAppXXX constants). The other files found in the external storage space are accessible in read-only.

Look Like USB thumb drive also same
