Sorry for the title of the thread. Managed to post accidentally before re-writing it. If a mod is free could they please amend it to something like this: "Looking for the best way to share a unique id/QR code that one user would share online or via WhatsApp/Messenger so that other users could load it"
For an update to an existing app I want to be able to allow a user to set up something on one device in the app and share it so that other users can load the same settings. The app already uses an online database so that would be the way to carry the data between two users but I'm not sure the best way to share it. I want to avoid text boxes at all costs as they just don't work well in AppGameKit so there's no chance of sharing a text string that a user can type in or copy and paste as AppGameKit doesn't have copy and paste on mobile devices.
One way I'm thinking is to create the settings on the device that would generate a unique id, store that id in the database (which I can do) and then create a QRCode image from that unique id that can hopefully be shared with the ShareImage function (haven't tried it on a device yet). I'm guessing the other user would either scan the QRCode if it was shared online by the first user or they would load the image if they were sent it and I'd use QRDecode to return the string and then find the match in the database to load the original settings.
I've written a few lines of code to QREncode a string, save the image, load the image, and QRDecode the image but I haven't been able to test it until later as my desktop at work doesn't have WiFi so I can't test it on the device or see if ShareImage works etc.
Is this the best way in AppGameKit? Are there other methods that I just haven't thought of?
