(Using VS2015 on Windows 8.1)
I created a new Xamarin Forms PCL project. The Xamarin forms version was 1.3.3.... I decided to get this upgraded to the latest-and-greatest. That process in itself went fine. However in the .droid nuget collection somehow it was decided that 4 packages Xamarin.Android.Support.Design/.v7.AppCompat/.v7.CardView/.v7.MediaRouter needed to be added to the packages.config. The version of all these four packages is 220.127.116.11 and nuget immediately shows that they need to be upgraded to 18.104.22.168 (Why didn't they just get installed?)
At this point I'm already having doubts about the quality of the upgrade proces. Anyway, I decided to see what happens when I build the Android project.
I then get this error:
C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(290,2): error XA5209: Unzipping failed. Please download https://dl-ssl.google.com/android/repository/android_m2repository_r20.zip and extract it to the C:\Users\marti_000\AppData\Local\Xamarin\Android.Support.v7.CardView\23.0.1\content directory.
3>C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(290,2): error XA5209: Reason: C:\Users\marti_000\AppData\Local\Xamarin\Android.Support.v7.CardView\23.0.1\android_m2repository_r20.zip is not a valid zip file
Ok, time to upgrade those four new packages: a world of hurt is the expression. Uninstalled the Android SDK and re-installed it etc.
Am I the only one experiencing these difficulties and if so, what is it that I am doing wrong? At this moment I'm on 1.3.3.. This functions but not being able to upgrade makes me unsure whether or not I'll experience problems when deploying etc.
