Glad to be back on these forums. I used to be AppmobiTyler and had awesome badges but I couldn't change the username and figured a new account was needed. I now also have more of a drive to re-grab those badges!
Warning: I didn't work on the creation of Crosswalk, but this is my understanding of the technology.
Crosswalk adds 20-25MB when compiled on the local machine or in the cloud since to my understanding it is packaging up chromium, enabling WebRTC, WebGL and others goodies though code. We realize this is sub-optimal but this is the initial release and we're working on streamlining now.
Thanks for bringing this testing friction issue up. Our team is always looking for what users want and I'll bring this issue up in our next meeting.
Most importantly on this thread:
We think we fixed the Crosswalk build issue
We noticed not just construct 2 people were having issues and found a bug in the build system. Anyone who has tried and failed please retry and see if you're still getting errors. If so then just message me so we can continue to track down the issue :D
