Why Empty Xamarin Form App use soo big cache memory on android?


I try to create very basic Blank App Xaml (Xamarin.Forms shared) with Xamarin for Visual Studio 4.2 and deploy It to my android device.
My empty xamarin app use about 60MB of cache after I check on app settings on my phone,

I tried deploy with Release configuration, but error appears:

Error The "LinkAssemblies" task failed unexpectedly.
Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Reference to metadata item 'System.Void Android.Widget.TextView::SetTextAppearance(System.Int32)' (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.Widget.TextView::SetTextAppearance(System.Int32)

    I just create a new app with (Blank App Xaml (Xamarin.Forms shared))-Template and deployed it to my phone. It needs only ~7MB.
    Measured with Android Device Monitor
