No it wasnt a wrong version, you simply dont ship the binaries (dll) for Android, or iOS, or linux or mac 
So i had to rebuild the solution, and compile to the targets (android, ios, etc.) in shipping mode.
Now it works.
Thanks.
Btw : why dont you include stuff like a node for remove playercontroller, or spawning actors from construction script? I can give you my bp library if you want.
