Main_btnLogin - it's a Login button on the Main screen. This app works on hunders other phones without any problems - I have never seen this error before.
This morning it was Ok, I didn't chnange anything - what does this error means?
I agree, that is a mystery, and I don't understand too.
But it seemed odd that Java would be off looking in libraries for something with name false - I would have thought that the boolean False value would be baked-in to the compiler, rather than be an optional extra.
