I have managed to get B4JPackager11 working but find I have a problem. Each .exe package generated by B4JPackager11 is roughly 55MB I run 16 B4J modules on AWS EC2 instances => 880MB total I also run 7 B4J modules on small headless/legless field PCs => 380MB total The disk space is not so much the problem (although it offends my sense of efficiency) however all these PCs are remote and periodically require updating - meaning upload times are a bit of a problem. I have tried merging...

Hi everyone, today I updated all the packages with the SDK Manager. After that, the app was crashing on a line about the QrCode reader made using the CameraEx class (there is a tutorial in the forum).
