Hiding the application from the launcher

Hi guys!
I want to check my application's licence with an another app. In Poweramp, there is a way in "Poweramp Full Version Unlocker" to hide the "license app" from the app drawer, so it won't "disturb" the user after that. Do you know any Xamarin.Android implementation for this case? I want to hide it only from the launcher.
Thank you!
