Creating a MonoDevelop application

I'm trying to create a Mono-for-Android application in MonoDevelop. I'm on Windows 7 64-bit, and my MonoDevelop version is 2.6 Beta 3.

When I enter an application name and hit the forward button, it gives me the following errors,

File Activity1.cs could not be written.
File Resources could not be written.
File Properties could not be written.
File Assets could not be written.

What's the problem?

Error details for error 1

Get similar details for other errors.

This is what I get when I install the AddIn:

Also when I hit Tools>Options>Other>Mono for Android SDK's, I get the following error(and error details) in a pop-up

回答1:

I ran into the same error and found a solution by seeing Daniel Soto's answer to Error creating Android app. Basically, install the 2.5.90.3 trunk build of MonoDevelop here.

I was able to continue.

Somehow you have a version of the Mono for Android addin that doesn't match your MonoDevelop version. Try updating MD to 2.6 b2 and then update the addin through the addin manager.
