Xamarin.Android Conflict between assemblies

Question

I'am facing a ridiculous issue on Xamarin.Android. I'am replacing the basic Actionbar by a Toolbar in my App. I want to support from Android 4.0.4 to newer Android versions. So i installed with Nuget packages (Visual studio) this package:

Xamarin.Android.Support.v7.AppCompat which install this package too: Xamarin.Android.Support.Fragment

Well it's ok but i use this package in order to scan Qrcodes and Barcodes: ZXing.Net.Mobile

Error:

FragmentStatePagerAdapter exists in 'Xamarin.Android.Support.Fragment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' and 'Xamarin.Android.Support.v4, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

So i decided to remove one of them but ZXing.Net.Mobile use Xamarin.Android.Support.v4 and Xamarin.Android.Support.v7.AppCompat use Xamarin.Android.Support.Fragment .

Is there a solution for this kind of issue ?

Thank you !

Solution:

Install Xamarin.Android.Support.v7.AppCompat 23.4.0.1 and upgrade when Zxing retarget packages. 2.4.0.1 = July 2016 < September 2016 (Package split, explained in first answer)

Answer 1

The answer is that ZXing.Net.Mobile will need to retarget and use the Xamarin.Android.Support.Fragment package as the v4 package has been split into multiple packages:

With this release, the v4 Support Library has been split into several smaller modules:

• support-compat
• support-core-utils
• support-core-ui
• support-media-compat
• support-fragment
