Could not resolve reference to 'Android.Support.V7.App.NotificationCompat/MediaStyle'...

Hi,
I’ve been using your plugin for a new project and it worked really well (I do really owe you my compliments, a really clean and fast solution for medias) until I switched from Debug to Release.

When in release, trying to build the solution, I got an unresolvable error

Severity Code Description Project File Line Suppression State Error The "LinkAssemblies" task failed unexpectedly. Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could not resolve reference to 'Android.Support.V7.App.NotificationCompat/MediaStyle' (defined in assembly 'Plugin.MediaManager, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null') with scope 'Xamarin.Android.Support.v7.AppCompat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

The project has latest Xamarin.Forms tools and latest Xamarin.Android tools, here details:

• NETStandard.Library, installed in: PCL v2.0.3
• Xamarin.Android.Support.Design, installed in: Project.Android v27.0.2.1
• Xamarin.Android.Support.v4, installed in: Project.Android v27.0.2.1
• Xamarin.Android.Support.v7.AppCompat, installed in: Project.Android v27.0.2.1
• Xamarin.Android.Support.v7.CardView, installed in: Project.Android v27.0.2.1
• Xamarin.Android.Support.v7.MediaRouter, installed in: Project.Android v27.0.2.1
• Xamarin.Forms, installed in each project (PCL, Android, iOS), v3.1.0.697
• Plugin.MediaManager, installed in each proj(PCL, Android, iOS), v0.4.5

This packages (exception made for Plugin.MediaManager obviously) are the default, generated by the system within the solution.

Steps to reproduce 📜

1. Create new Xamarin.Forms PCL solution

2. Install Plugin.MediaManager

3. Switch build to Release

4. Rebuild project

Things I tried

1. Install Plugin.MediaManager.Forms in each project in the solution with and without Plugin.MediaManager installed

2. Install Plugin.MediaManger only in Droid proj and installing Plugin.MediaManager.Forms in each project.

3. Tried a lot of combinations, also tried to download latest stable branch and generate .dlls.

4. To check if it was just my solution I tried to create a new, empty, PCL project, including both Android and iOS, when installing the NuGet it still gave me the same error.

Still couldn’t manage to solve the situation.

Expected behavior 🤔

Build in Release without errors

Actual behavior 🐛

Can’t build in Release

As also said in a lot of other issues. This project is a lot of work, and it would help a lot if your company starts paying for what they use. I can provide an updated version a lot sooner when that happens, otherwise you got to wait until it is finished.
