java - Trying to bind glide in Xamarin -

i want bind library glide in xamarin, getting stuck oncom.bumptech.glide.bitmapoptions.

as interface, binds ibitmapoptions, can't find name in namespace. have tried looking in output folder, interface seems have disappeared.

i looked @ other errors getting , binding project can't find 2 other interfaces. looked in java code, , see uses <?, ?, ?, ?> generic syntax.

is there problem syntax makes cannot bound? if so, how solve this?
