Hello, here I have the definitive solution for those apk export problems of our projects, it has happened to me.
1) If the apk project fails and if you have another cyberix project that I installed before it is important to uninstall it and in this way you can install the current one if not here the 2 step.
2) Before exporting your project as apk, rename the file.
Any of those steps can work !! And remember, if the platform blocks the file, contact the administrator
