Android Code Snippet File GetCreationTime alternative

This function is working great in recent android versions.
But in older ones not working, I googling and find this working in all android versions:

Public Sub GetCreationTime (Dir As String, FileName As String) As Long
    DateTime.DateFormat="yyyy-MM-dd"
    DateTime.TimeFormat="HH:mm:ss"
    Dim jo As JavaObject
    'jo.InitializeContext
    jo.InitializeStatic(Application.PackageName & ".currentmodulename")
    Dim a As String = jo.RunMethod("filecreate",Array As String(File.Combine(Dir,FileName)))
    Dim aa() As String=Regex.Split(" ",a)
    Return DateTime.DateTimeParse(aa(0),aa(1))
End Sub

#If Java
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;


public String filecreate(String f) {
           File file = new File(f);
        long creationTime = file.lastModified();
        Date date = new Date(creationTime);
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.getDefault());
        String formattedDate = sdf.format(date);
        return formattedDate;
}

#End If
