问题 I've been messing around with Mono for Android for a little while now. I am wondering how (or if it's possible) to access network files located on my NAS. I was really hoping it was going to be as easy as var files = System.IO.Directory.GetFiles("\\NAS-NAME\SomeDirectory\", "*"); Unfortunately, I'm getting this error message, so I'm guessing it's not quite as straight forward as a standard .NET application: Unhandled Exception: System.IO.DirectoryNotFoundException: Directory '\\NAS-NAME

问题 The Android device I am using does not have any touchscreen. All it has is a touch pad that can generate KEYCODE_DPAD_UP, KEYCODE_DPAD_DOWN, etc. However, I am not sure if my Xamarin app is responding to these events. Is there any setting that one can enable to identify current selection among a group of controls. When I go the device's home screen and use the DPad keys to move around, I see a thin square around the icon that is currently selected. I am hoping there is a similar setting

问题 I am trying to use popup balloons over custom overlay items in Mono for Android. I found this project https://github.com/jgilfelt/android-mapviewballoons, however it's written in Java. I've started manually converting it to C#, but it's a bit over my head. I've read that you can import java files to Mono, but I'm not sure which path is easier at this point.
