Thanks for the previous info in this thread, it's been useful!
Adding to the questions: how does one include external resource files now? To be specific, my app has the following in the descriptor:
<application android:hardwareAccelerated="true" android:windowSoftInputMode="adjustResize" android:enabled="true" android:allowClearUserData="true" android:allowBackup="true" android:roundIcon="@mipmap/icon_round">
For the android:roundIcon="@mipmap/icon_round", previously I would include the assets needed inside of the air33.1.1.633\lib\android\lib\resources\app_entry\res folders. However now when trying to build aab I get the error:
aapt2 tool failed in linking:C:\Users\KD\AppData\Local\Temp\f81ba8bb-356c-43bd-a0bf-a4e1ee066a9b\AndroidManifest.xml:8: error: resource mipmap/icon_round (aka air.com.trainnovation.trainnovation:mipmap/icon_round) not found
What's the proper way now?
