xamarin - Failed to use Android Support Library v4

Question

I'm trying to use the DrawerLayout from android.support.v4 library. I have added Xamarin.Android.Support.v4 package using Nuget but I'm still not able to compile the application and I face the following errors:

It seems to me that I should add a jar or something like that to the Xamarin project, Please tell me how and where could I do this if I'm right at this point. Thanks for any help

Answer 1

For me this was caused by killing VS during the initial build of my first Xamarin project after a reinstall.

It looked as though the process had hung, but apparently it was downloading from google at a slow rate.

Quit Visual studio

Delete / rename c:UsersusernameAppDataLocalXamarin

Open the solution again

Clean the solution

Compile, wait until it finishes completely.

On Windows, use Resource Monitor to determine if a download is in progress.

MSBuild will be downloading from something.1e100.net.
