Heres my plan. Two people have my app and I need to get a bunch of data from one to the other.
The person receiving the data doesn't know that they might be sent something, they two people could be in completely different places in the world, so it can't be transferred locally.
So, our of maybe thousands of people who use the app, I could have it, host a bunch of data and then only my specified receivers could then get that data from me and have it in their app.
I am VERY new to server/network stuff, so as much detail in your responses would be hugely helpful.
Any help or tips on how to do this would be much appreciated, thanks.
Sounds like a classic client server.
Setup a server. Have app from user A send data to server. Send push notification to us B he has new data. When user B open the app have him poll the server for his new information.
