Shared data between apps

Solar2D General Questions/Discussion
#1

Hi, 

I’ve been playing with writing data to files in the hopes that i can test if a user has installed (and logged in) another app made by our company.

Is there any way that i can share data between 2 application when an open application can check the user data of the second application?  

Ideally I would like to be able to automatically great a user by their logged in name from another application and prompt them to login in app that need it or to be able to read progress made in the other app.

Does anyone know of a secure way i can save and read or pass this data between corona applications?

Thanks!

I’m fairly sure the data is sandboxed so you can’t reach it from another app.

I think you would have to upload some user data (id of the app, device ID etc) to a server, and then retrieve this when any of your apps start.

There are ways to check to see if you have another app installed. It involves using system.canOpenURL() to check to see if the app is there. You may have to define a URL scheme on iOS an setup some intent filters on Android (google or search the forums for previous discussions on it).

As far as sharing data, at least for iOS, I believe multiple apps from the same provider can share some level of data through the iCloud Plugin. Probably something similar can be done with GPGS as you can setup multiple apps to access a  single GPGS setup.
