My android build fails after build and this is the error log i get Total time: 1 mins 16.631 secs Stopped 0 compiler daemon(s).

This is probably related to this: https://www.codenameone.com/blog/video-new-defaults-barcode-qrcode-changes.html
You can workaround this by using android.gradle=false in the build hints. However, I'm guessing its related to some cn1lib or build hint you added. But it seems the build error log you provided is partial so I don't see any issue there.
