Descrizione

type: feature request

From the Readme, I am following Setup Instructions, then Android. Here it says "pay special attention to the Android instructions for ProGuard." but the referenced Proguard section does not exist.
I have been using this library with R8 successfully in the past, but recently tried out full mode, and got following exception:
