You can try the following

1. Add this to your app.gradle located in the App_Resources/android

   android {
   defaultConfig {
      multiDexEnabled true
   }
   }

Or

2. Add this to your app.gradle located in the App_Resources/android

   configurations.all {
   resolutionStrategy.eachDependency { DependencyResolveDetails details ->
   def requested = details.requested
   if (requested.group == 'com.android.support') {
       if (!requested.name.startsWith("multidex")) {
           details.useVersion '27.1.1'
       }
    }
   
   }
   }

@triniwiz

The 1st option gave me a new error about duplicate Zip entry. The 2nd one appears to work.

@triniwiz If i'm using NS 4.2.0, and your 1st option, what version should be in the details.useVersion? Does it matter if it's 27.1.1? Is there a way to match it with what i've been using until now? It's just, I got this error just today after months of working on the same project
