Nuget: Using Xamarin Forms and Google GCM packages together

votes

I'm implementing push notifications on my Xamarin Forms Android app and currently installing required NuGet packages.

However, I've come across a package conflict issue: Xamarin Google Play Services (GCM) version 42.1001.0 and Xamarin Forms version 25.1.0 can't be installed on the same project, which seems to be due to the dependencies.

I read from the Xamarin forums https://forums.xamarin.com/discussion/57283/unable-to-find-a-version-of-xf-compatible-with, the packages require the exact version for their dependencies, which is unfortunate because there are some overlapping dependency packages.

Is there a way around this?

The installation log when installing Xamarin Forms then Google Play Services:

I just added Xamarin.GooglePlayServices.Gcm v42.1001.0 to a monoandroid71 targeted w/ the latest Xamarin.Forms(v2.3.4.231) and ended up with a package.config of:

<?xml version="1.0" encoding="utf-8"?>

For anyone that's having this same issue, try updating all your packages from the project level. If you get errors, try manually updating each package, run Visual Studio as admin and retrying several times (believe it or not, there was a pesky package that updated after trying to do so 4 times!).
