Android Version: 9;
Language used: C# in XAMARIN
i use this code:
string fileName = Path.Combine(Android.OS.Environment.ExternalStorageDirectory.AbsolutePath, "Test.txt"); //Pass the filepath and filename to the StreamWriter Constructor StreamWriter sw = new StreamWriter(fileName); //Write a line of text sw.WriteLine("Hello World!!"); //Write a second line of text sw.WriteLine("From the StreamWriter class"); //Close the file sw.Close();
And get this error:
Android does not contain a definition for 'OS'
