AndroidVisionMaster enviroment setup problem. I seem to be running in circles trying to get a B4A sample project to compile and install. I have written several other applications but the bar code scanner seems to have very specific requirements for the environment. I am now getting an error on compile that I do not understand. Can anyone help please?
