Problem running a MonoDevelop App

问题

This is a continuation of my Problem in creating a MonoDevelop App question,

The problem is solved, I am able to create an App, but now I'm having problems running it,

When I run the application I get an error saying,

C:\Users\tarun\Documents\Projects\myAndroidApp\myAndroidApp\aresgen:

Error 1: Could not find SDK platform directory 'C:\Program Files (x86)\Android\android-sdk\platforms\android-4'.

Ensure you have installed support for this Android platform version in the Android SDK Manager. (1) (myAndroidApp)

Also have the following problem,

when I hit tools > options > other > Mono For Android SDKs, I get the following error,

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Mono.Posix, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756' or one of its dependencies. The system cannot find the file specified.

Also, I get this same error (the one mentioned above), when I right-click project > options > Build > Mono For android build/Mono for android applications

My MonoDevelop version is 2.6(2.5.90)

Help appreciated !

Believe it or not, I read about a problem with the SDK where it can't parse the spaces in the path. Try reinstalling the Android SDK to a path without spaces. In my case, I installed it to C:\Android\android-sdk.
