I have some strange problem, we are using Gauge Library (see attachment) in one project it works fine but gives error in another project. Both projects are exactly same... below is error dump...

I am attaching two projects, demo-gauge-not-working.zip contains library files, demo-gauge-working has only B4a project but uses same library.
