I tried this already but then there is this error:
B4A Version: 7.80
Parsing code. (0.01s)
Compiling code. Error
The object reference was not set to an object instance. [Translated from German: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.]
But there is no hint in the logs (there are no logs) where this error comes from, so I guessed the library can't be used with 7.8 and because of this, this post ^^
