Try to add the jar files (make aar into jar) into Fast >> lib>> appinventor

Then in shell use fast sync and try build

Prem_Gupta · June 11, 2025, 12:32pm

i already add (as per my knowledge)

can U guide me via screenshot or video🙄

mahmoud_hooda · June 11, 2025, 12:46pm

First you need to add the libraries names to fast.yml as you did but under of dependencies

Secondly just run fast sync
