Android Question ExternalWritable under Android 6

[peacemaker]

Under Android 6 without removable SD-card - ExternalWritable = True, but SQLite db file cannot be copied by

Sub CopyDBFromAssets (FileName As String) As String
    Dim TargetDir As String
    If File.ExternalWritable Then
        TargetDir = File.DirDefaultExternal
    Else
        TargetDir = File.DirInternal
    End If
    If File.Exists(TargetDir, FileName) = False Then
            File.Copy(File.DirAssets, FileName, TargetDir, FileName)
    End If
    Return TargetDir
End Sub

and TargetDir = File.DirDefaultExternal

In the line with File.Copy - there is the error:

Error occurred on line: 531 (inetsrv)
java.io.FileNotFoundException: /storage/emulated/0/Android/data/peacemaker.energeniepowermanager/files/db.sqlite: open failed: ENOENT (No such file or directory)

And mostly on Samsungs.
How to be sure ?

1. It will only happen if you set the targetSdkVersion to 23.
2. I've updated DBUtils to use RuntimePermissions.GetSafeDirDefaultExternal: https://www.b4x.com/android/forum/threads/dbutils-android-databases-are-now-simple.8475/#post-47359
