Hello,
We are trying to integrate a MapView in our application, unfortunately we
can't construct a solution we can build successfully. We've tried to build
the sample from
https://github.com/xamarin/monodroid-samples/tree/master/MapsAndLocationDemo_v2
in Xamarin Studio, but only managed to build the GooglePlaySerives project
(with 3 warnings:
/JARTOXML : warning J2X9001: Couldn't load class
com/google/android/gms/maps/SupportMapFragment :
java.lang.NoClassDefFoundError: android/support/v4/app/Fragment
JARTOXML : warning J2XA006: missing class error was raised while reflecting
com.google.android.gms.maps.SupportMapFragment$a :
android/support/v4/app/Fragment
JARTOXML : warning J2XA006: missing class error was raised while reflecting
com.google.android.gms.maps.SupportMapFragment$b :
android/support/v4/app/Fragment/
)
The SimpleMapDemo fails with "MSBuild operation failed".
Anyway, I won't go into details with this experience, since we need a
solution for Visual Studio.
I've tried to reconstruct the solution in Visual Studio, but the building of
GooglePlaySerives seems to create a very small (empty?) dll, so the
SimpleMapDemo does not see the namespace Android.Gms.
I've tried to add to the references the dll generated by Xamarin Studio
(which has a 9.21 MB size), with this I get -The
"ResolveLibraryProjectImports" task failed unexpectedly.- error.

We are using Mono for Android 4.4.55 (an update to 4.6.x is not possible due
to very big build+packaging times, as mentioned here:
http://mono-for-android.1047100.n5.nabble.com/Slow-Build-und-Packaging-Process-amp-few-other-things-after-update-td5713139i20.html)
Could you provide us a working sample for Visual Studio, or help us solve
the above issues?
Thank you and regards.
