c# - Cannot create files on Android with Xamarin

Question

I have a Xamarin-Studio App for Android and I simply want to download files and save them locally. But when I try to create a file in the files folder I get an exception:

File.Create("data/data/com.company.app/files/newFile.png");

gives me:

System.UnauthorizedAccessException
Access to the path 'data/data/com.company.app/files/newFile.png' is denied.

What am I doing wrong?

You should use Environment or IsolatedStorage. For example:

var path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
var filename = Path.Combine(path, "newFile.png");
