'Xamarin Android Archive error. Invalid Android Archive (no .APK files)

I am trying to publish an APK for a PCL Xamarin project. I am following these steps: Publishing An Application and at the 'Archive for Publishing' step I get the following error after a small wait:

"Failed to create App archive 'MyProject_Test.Droid' Invalid Android Archive (no .APK files)"

I have rebuild my Solution and tried running Visual Studio with Administration Privileges. If you need any log files or details from me, I will provide those you request (not sure which log files will help with this)

I am using Visual Studio 2017 Enterprise.

Solution 1:[1]

For anyone that happens onto this the way I managed to get it working:

  1. Close VS
  2. Go to your project folder
  3. Open the bin folder and delete everything
  4. Re-open VS and build your solution and then try the archive option
