Hello,

i know path of my photos ("/storage/emulated/0/DCIM/Camera/") and i want to have list of all images in this folder. I tried with this ->

B4X: 
Dim mylist As List
    mylist.Initialize
    mylist = File.ListFiles("/storage/emulated/0/Camera/")
    Log(mylist)

but I always get in logs -> (list) not initialized

any ideas?

Click to expand...

Then you call ..
B4X: 
    mylist = File.ListFiles("/storage/emulated/0/Camera/")

Notice anything strange ?


Also .. You do realize this path will be different on other devices.

As well as mangojack have told you, I think probably you should have in mind runtime permissions too, to access an external folder.

File. ListFiles (Dir As String) As List
Returns a read only list with all the files and directories which are stored in the specified path.
An uninitialized list will be returned if the folder is not accessible.

Yes i know and I use this code ( written by Erel)

B4X: 
Sub GetExternalStoragePublicDirectory (name As String) As String
    Dim jo As JavaObject
    jo.InitializeStatic("android.os.Environment")
    Dim path As Object = jo.RunMethod("getExternalStoragePublicDirectory", Array(name))
    If path = Null Or File.Exists(path, "") = False Then
        Log("No such folder.")
        Return ""
    End If
    Return path
End Sub

B4X: 
GetExternalStoragePublicDirectory("DCIM")
