Error when compiling app with Xamarin Facebook API

SimonCahill

Hey there,

I've only just recently started using Xamarin, so please excuse my ignorance.

I have an application which uses Facebook to log users in, and might (depending on the customer) post achievements, etc. to Facebook.

So far, so good, the UI is in tact, a bit laggy, mind you, but it works nonetheless. I now wanted to add the Facebook API, as I've done a few times before, with pure Java.
I added everything I needed to the manifest.xml, I added the v4 and v7 support libraries, and of course set everything up with Facebook.

Now, when I go ahead to compile the app, I get two compiler errors:

1) /Users/profile/Projects/xxx/Droid/obj/Debug/library_projects/Xamarin.Facebook/library_project_imports/res/layout/com_facebook_device_auth_dialog_fragment.xml(0,0): Error APT0000: No resource identifier found for attribute 'cardBackgroundColor' in package 'de.nwt.xxx' (APT0000) (xxx.Droid)

2) /Users/profile/Projects/xxx/Droid/obj/Debug/library_projects/Xamarin.Facebook/library_project_imports/res/layout/com_facebook_device_auth_dialog_fragment.xml(0,0): Error APT0000: No resource identifier found for attribute 'cardElevation' in package 'de.nwt.xxx' (APT0000) (xxx.Droid)

I've tried adding a colour named "transparent" to my colours.xml (transparent is the name the API is looking for), but to no avail. I've updated all the packages in hopes of fixing it that way, but nothing has helped.

Any ides or solutions would be very much appreciated!

No resource identifier found for attribute 'cardElevation' in package 'de.nwt.xxx' (APT0000) 

your error complaining about atribute cardElevation and cardBackgroundColor.
Make sure you added Xamarin.Android.Support.v7.CardView package into your Solution.

I added everything I needed to the manifest.xml, I added the v4 and v7 support libraries, and of course set everything up with Facebook.

I've added this library to the solution.
However, it still does not work. I've also cleaned and rebuilt the solution, also to no avail.

Ok, so after rebooting the machine, and restarting Xamarin Studio, the error mentioned above has gone. Maybe a caching problem or something of the sorts?

Anyways, now I get a different error:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Bolts.Tasks, Version=1.0.0.0, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?

Any ideas on this?

it means Xamarin Studio can't find your Bolts.Tasks.dll.
is it from nuget package?
try to rebuild your solution.
