Last compiled this project successfully about a year ago and now it won't compile. Nothing has changed as far as the code is concerned. In fact I wanted to use a new library (dgUID) to use some of it's functions and now have this issue. I've updated my SDK to latest release and unfortunately this has not fixed the problem. A bit puzzled what broke seeing I haven't changed it for almost a year. Any ideas?

Thanks

Update B4A to 10.5. https://www.b4x.com/b4a.html

Follow ALL steps exactly as for a first time install, and both Android SDK Command line tools and required resources
Be sure to use 7-Zip to extract downloaded archives. (Windoes extract can/does corrupt folder structures)
