I would like to know, if is it possible to use b4xpages library with no need to have .bal file in The compiled project. If I remove .bal file and The reference to it from .B4a file, app crashes. Android system UI report error, that app has stopped. I do not know how to remove The default generated button with its text Click from .bal file by using GUI designer. Simply pressing Del key do not remove it when I open The project and if I run The designer from The menu.
