Hello, I'm trying to compile Don Manfred's example from the Firebase Ui library and I get the following error.
Version B4A: 9.01.2 Java version: 11 Analysis code. (0.03s) Structure of construction folders. (0.06s) Compilation code. (0.05s) Compiling design code. (0.00s) Organization of libraries.

Regards Thanks for your help

Did you added DesignSupport and AppCompat library to your app?
Are you using android.jar from platform 28?
You are using the provided res folder inside your app?
