Thank you for providing the archive.
Do you have source code for all of these versions? As far as I know, these are all licensed under GPLv3. Under GPLv3, I believe that if you are distributing the binary of a program, you have to be willing to provide the source code to a user upon request. So it would be nice if you included source code with the apks by default.
edit- actually tbh I do not know enough about copyleft / gpl to know if you need to provide source code. Maybe it is just the developer of the fork that needs to provide the source code, not you. idk.
