APK file size

Hi experts,

I created a simple Android application using xamarin and vs 2010, everything works fine. I checked "Bundle Assemblies into Navtive Code" option from "Mono Androd Options". After that, when I looked at the apk file size it is around 20 MB.

I want to compile the code into native and is there anyway where you can reduce the apk file size?

Thanks Murali
