Android build Fails with - D8: Program type already present

[unstableair]

Cordova build for Android fails with:

> Task :app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED
D8: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: 
  Program type already present: android.support.v4.os.ResultReceiver$1

This is easy to recreate:

cordova create test com.test test
cd test
cordova platform add android@latest
cordova plugin add cordova-facebook-audnet-sdk
cordova build

Cordova 9.0.0
Android 8.0.0

Installing cordova-plugin-androidx allows the build to complete but app crashes immediately on open. Environment works fine if cordova-facebook-audnet-sdk is not installed.
