.NET for Android warning XA4306
d8/r8 does not support using custom multidex.keep
files
if minSdkVersion
>= 21, e.g. devices where native multidex is
supported. In theses cases, d8/r8 calculates the contents of the main
classes.dex
without rules specified by developers.
This change in d8/r8 appeared in version 1.4.93.
Verify you are not declaring any MultiDexMainDexList
build items.
Consider submitting a bug if your application does not function
after removing any MultiDexMainDexList
items.
