Description Mikael Nensén 2014-11-10 02:08:05 UTC
Description of Problem:
When I build our Xamarin.Forms Android client against API 16 (Compile, Minimum and Target set to API Level 16) I get a linker error; trying API 15 also yields a linker error, which I'm reporting separately.

Steps to reproduce the problem:
1. Create a Blank App (Xamarin.Forms Shared)
2. Update nuget packages to:
Xamarin Support Library v13 -
Xamarin Support Library v4 -
Xamarin.Forms -
3. Select Release build configuration (Activates the linker, not activated during Debug build configuration)
4. Set Compile, Minimum and Target Android version to API Level 16
5. Build

Actual Results:
The "LinkAssemblies" task failed unexpectedly.
Xamarin.Android.XamarinAndroidException: error XA2006: Reference to metadata item 'System.Void Android.Views.View::set_TextAlignment(Android.Views.TextAlignment)' (defined in 'Xamarin.Forms.Platform.Android, Version=, Culture=neutral, PublicKeyToken=null') from 'Xamarin.Forms.Platform.Android, Version=, Culture=neutral, PublicKeyToken=null' could not be resolved. ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void Android.Views.View::set_TextAlignment(Android.Views.TextAlignment)

Expected Results:
Everything builds without any errors.
