i have no idea why happens, ideas helpful, please!

while xamarin supports api levels of android, xamarin.forms support api level 15+ should set minimum sdk 15. here our documentation:

http://developer.xamarin.com/guides/cross-platform/xamarin-forms/introduction-to-xamarin-forms/#requirements

this means xamarin.forms supports 94% of android devices: https://developer.android.com/about/dashboards/index.html?utm_source=suzunone
