I have received this error message whilst trying to compile under 1.48:
The line that stops the compilation is:
This hasn't changed since my first version of my app.
Interestingly, I reverted back to the 1.41 release and it compiled OK, but when I then go back to 1.48, it stops at this line again.
B4X:
Compiling code. Error
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
B4X:
File.MakeDir(File.DirDefaultExternal,"/images")
This hasn't changed since my first version of my app.
