Using B4A v2.0 with two GLObject Types (agraham's OpenGL v1.7), one each in two Activities.
The compiler complains Error parsing program: "item with the same key already exists".
When I bypass one Activity so that just one GLObject is in the project, then the code can
be compiled.
B4A v1.9 compiled without error, irrespective of how many GLObject Types are in use.
